Abstract:

ABSTRACT The Calaveras Dam Replacement Project, a major construction project completed in 2019, involved hundreds of workers using heavy earth-moving equipment and mining operations, including blasting, drilling, rock crushing, and other operations designed to move millions of cubic yards of earth. Much of the material was composed of serpentinite, blueschist, and other rocks that contain chrysotile and a variety of amphibole minerals, including glaucophane, winchite, actinolite, tremolite, and other asbestos-related amphiboles. This article explores the unique characteristics of the blueschist that required extensive protective measures to be undertaken by the contractor to protect workers and surrounding sensitive receptors. This article will provide an overall summary of the dimensional characteristics of the airborne blueschist elongate mineral particles encountered during construction activities to compare and contrast current understanding of cleavage fragments versus asbestiform mineral fibers.

Abstract:

The introduction into service of the Westland manufactured Apache AH Mk1 has coincided with a thrust within the UK armed services for a greater emphasis on amphibious operations within the littoral environment. From this background has emerged a requirement for an embarked, attack helicopter capability, for which the Apache AH Mk1 has been earmarked. However, this helicopter being, by design, optimized for the battlefield environment, cannot be presumed to adapt to the naval environment without presenting certain challenges. This article describes how Westland Helicopters Ltd has sought to determine the feasibility of conducting embarked operations with Apache AH Mk1 by deriving limits to be respected during Ship Helicopter Operating Limits (SHOL) trials using a variety of analytical methods. Aspects of operation considered include aircraft lashing, landing, stability on deck with rotors running or stationary and when being towed, rotor engagement and disengagement, ground resonance, and main rotor spreading and folding. The article considers further aspects of importance to embarked operations and summarizes the trials process that results in an operational envelope for service use. It concludes that a practical operating envelope can be achieved, anticipates a successful outcome for the SHOL trials, and includes a projection for future activities to enhance the aircraft's maritime operational capabilities.

Abstract:

This article argues that American naval force packages built around aircraft carriers and amphibious assault ships no longer serve maritime security interests as effectively as in the past. It further claims that the current commitment in the published maritime strategy of the United States to the twin shibboleths of “carriers and amphibs” comes from a variety of attitudes held by senior decision makers and military leaders. This commitment betrays both cultural misunderstanding or even ignorance of seapower—“sea blindness”—as well as less than rational attachments to two operational capabilities that served the United States well in the past, but in doing so engendered emotional commitments that are little grounded in the facts.

Abstract:

During the years of peace between the First and Second World Wars, it is clear that Navy and Marine Corps planners failed to sufficiently address several problems that would confront American forces in the looming conflict with Japan. Of these, one of the greatest omissions concerned the application of naval and aerial fires in support of an amphibious landing. Though American officers recognized and resolved concerns over landing craft, logistics, casualty evacuation procedures, communications, and much more, planners failed to adequately address the difficulties of controlling and coordinating supporting firepower in a triphibious operation. The 1934 Tentative Manual for Landing Operations highlighted the individual roles of naval gunfire and air support without confronting the more general coordination of land, sea, and air efforts, and it minimized the importance of flexibility and continuous coverage in amphibious fire support.

Abstract:

There are calls by some experts to accept that an amphibious assault of coastline is simply too risky to attempt due to current threats. So, what are the challenges facing amphibious assaults? Is the amphibious assault still a viable type of military operation in the current threat environment? These questions are at the heart of the mission and role of the United States Marine Corps. This analysis delves deep into the problems facing amphibious assaults, and it serves as a primer for future discussions pertaining to improving amphibious assault capabilities.

Abstract:

To determine the ideal landing beaches in amphibious operations must meet the requirements / criteria that have been determined, because it serves as an important component in the choice of landing beaches. The criteria include the type of beach, gradient beach, the basic material of beach, long beach landings, the type of breaking waves, tide, the kind of obstacles beach, ocean currents, the field behind the beach, the reference point mark landing beaches and access to the exit / entrance beach , In determining the selection of the landing beaches Marine / Navy had not done the calculation / mathematical model and not using a scientific method, such instances it is necessary to make a decision-making model in the case of election of the landing beaches in amphibious operations exercise. This study aims to determine the location of the landing beachesusing Fuzzy MCDM. The use of this method is the solution to produce a more objective group decision in the selection of an amphibious landing beach which data are accurate and reliable to help solve problems that are multi-criteria. There are 11 (eleven) criteria and 4 (four) alternatives identified in this study. Of the 11 criteria which have the highest weighting criteria for the alternative chosen in the first rank third alternative, namely PPD 3. Keywords: Amphibious Operations, Fuzzy MCDM, Criteria and Alternatives.

Abstract:

Major Joseph DiDomenico’s study of U.S. Army influence on U.S. Marine Corps tank doctrine appeared in the Summer 2018 issue of this journal, titled “The U.S. Army’s Influence on Marine Corps Tank Doctrine.” Mobilizing an impressive array of primary and secondary sources, DiDomenico laid considerable credit for the Corps’ improvements to its nascent World War II tank and amphibious tractor doctrine on the Army’s Armor School at Fort Knox as well as the improved Army doctrinal publications that had emerged by 1944. Major DiDomenico excoriated the Marine Corps’ neglect of “critical vulnerabilities for armor supporting amphibious operations.” The benchmark for Marine Corps tank doctrine’s failures to “synthesize” Army tank doctrine for Marine Corps missions is unsurprisingly the Battle of Tarawa. According to DiDomenico, the failures registered at Tarawa “indicated an institutional ignorance in the operational art of combined arms.” This article presents some common misconceptions of Marine Corps tank policy and doctrine and aims to correct those misconceptions.

This article will use the wave making theory of uniform pressure side to calculate the amphibious air cushion wave. Moreover, the composited outside wave establishes the new wave that closer to the practical hull bottom wave. At the same time, utilize the flow continuity equation to build the air cushion system then to set up the perfect mathematical model of amphibious air cushion with six variances operation. In addition, forecast the divisibility of amphibious air cushion motion in wave. The forecast result can effectively affect the basic motion characteristic of the hovercraft. The simulation result can use for the deeper research of motor function for the hovercraft operation, the debugging and optimization of the control system.

ABSTRACTThis paper develops a method to determine the lift-drag ratio of air cushion craft and specifically the maximum value of the lift-drag ratio, its associated design speed, and related performance and economic measures. The method works from well-established equations for drag and power for air cushion craft. Such values are required to determine the performance and economic efficiency of the craft in many modes of operation. The method covers both amphibious and non-amphibious craft of the types used in both military and commercial operation. A basis is developed for an optimisation procedure to design future craft for maximum efficiency.

Abstract:

ABSTRACT Determination of the landing beach becomes a must for the Marine Forces of the Indonesian Navy as an element of the landing forces in order to carry out the task of amphibious operations in particular to determine the ideal landing beach location for the successful implementation of the task. Requirements on the determination of ideal landing beaches should be in accordance with predetermined parameters and serve as an important component in determining the weighting value of landing beach selection criteria. This study aims to determine the location of landing beaches by using the Preference Ranking Method Method of Organization for Enrichment Evaluation (PROMETHEE) combined into the Borda method. The research stages started from determining the value of criterion preferences to the landing beach alternative options analyzed by PROMETHEE method then processed again in Borda method. The PROMETHEE method is used to analyze individual decisions of decision makers, while the Borda method is used to manage group decisions from the PROMETHEE method of ranking. The use of both methods is a solution to generate more objective group decisions so as to obtain a ranking result against the selection of logical amphibious landing beaches and have an objective value in accordance with accurate data and greatly assist decision-makers to solve multi-criteria problems. From the results of this study can be seen that the location of the selected beach is the most feasible to serve as the location of landing beaches in amphibious operations is Beach 3 with a weighted value of 0.389.

Abstract:

The study aims to present, compare, and assess three different types of buildings considered as flood-resilient construction: building on piles (also called static elevation), amphibious building (also called can-float), and floating building in terms of their performance in the context of a semiwild river in a large city. The comparative multiple-case study covers three objects realized between 2014 and 2017 at the Vistula riverbanks in Warsaw, Poland: pile founded Beach Pavilion, amphibious Boulevard Pavilion, and floating Water Tram Terminal. The research was based on the blueprints analysis as well as on on-site observations in the phase of construction and operation and interviews. The general characteristic of the three resilient typologies has been confirmed in the study. The pile building has an almost unlimited range of operation regarding the water level on the cost of a relatively remote location from the river, but during an exceptionally extreme flood, it will be flooded. Floating buildings provide the best visual and physical contact with water, cannot be flooded, and may be relocated but access to them from land is hampered, especially during very low and very high water levels. Amphibious buildings seem to be a compromise of water proximity and reliability of operation in all circumstances. A closer look reveals technical problems with buoyant structures. In the case of the floating terminals, problems with mooring on the semiwild freezing river remain a challenge. The amphibious buildings are still in the phase of implementation, waiting for their first test in natural flooding conditions.

Abstract:

The modern strategy for the development of health care includes as one of the priorities maximum approach of medical services to the consumer. To solve this problem in the conditions of the Navy, it is advisable to create mobile medical complexes placed on specially equipped vessels. For the full and operational medical support of the fleet forces in specified areas of the world’s ocean at different distances from the main base sites, a system of marine mobile medical complexes should be created. In peacetime the system should include hospital ships, multipurpose vessels with a hospital on board, mobile polyclinic mobile complexes and high-speed ambulance boats. During the period of danger, the possibility should be provided for the rapid re-equipment of hospital and multifunctional vessels, as well as polyclinic complexes with an increase in evacuation capacity and an increase in the volume of medical care. For medical support of an amphibious assault operation on universal amphibious ships, a quick re-equipment of the premises specially allocated during the design process to medical facilities for emergency medical assistance and evacuation of the wounded to coastal medical institutions should be provided. In wartime, for the provision of medical care and evacuation of the wounded, vessels of various purposes must be used, the projects of which contain the capabilities and algorithms for their quick conversion into sanitary transports. Variants of the main tactical and technical characteristics of vessels of various classes intended for medical support of the fleet forces are proposed. A significant problem in the operation of medical vessels is their low patient load in the inter-transit period, which leads to the disqualification of full-time medical staff and reduces the quality of the maintenance of the vessel. When forming the operational-tactical model of operation of medical vessels, special attention should be paid to the staffing algorithms and ensuring that the courts are always ready to perform their tasks.

Abstract:

A new category of large-diameter adaptable amphibious wheel-legged robot is proposed in this paper. The proposed mechanism can climb obstacles better than existing designs. The Denavit–Hartenberg (D–H) coordinate system is used for kinematic analysis, and the constructed kinematic model is used to solve for these joint variables for a redundant robot. The control strategy is to plan both the foot trajectory of the amphibious robot, to optimize the operational performance in special environments, as well as the walking gait. Then the closed-loop control system is used. A simulation is used to verify the usefulness of the planned foot trajectory and walking gait for an entire running cycle, and a circuit is designed to solve a communication problem between the Arduino and the AX-12 servo. Finally, the foot trajectory of a single robot leg is captured by a three-dimensional motion-capture system to verify the rationality of the foot trajectory and walking gait.

Abstract:

The vehicle ride and handling analysis is one of the important aspects in vehicle dynamics. This paper takes a model of amphibious vehicle to establish the exact virtual behavior of vehicles riding and handling base on the virtual design parameter. This vehicle can operate both on ground and water, therefore the analysis model is developed using seven degree of freedom model for ground operation and one degree of freedom model for water operation. The seven DOF are moment of roll, pitch, yaw and all four tires motion while the rest is buoyancy. Therefore, the ability and limitation of the vehicle demonstrate the behavior of unexpected case happened. These facts in turn to be used to improve the ride and handling level during acceleration, deceleration, cornering and step steer. The model also capable to function on the water where as the design of the body work considers the buoyancy concept for stability on every condition of wave surface. The analysis of buoyancy and stability for this model shows the vehicle ability to perform in the state of equilibrium condition under heeling and capsizing on water surface.

Abstract:

Unmanned aerial vehicles (UAVs) have gained a lot of attention in recent times due to its versatility in deployment for multifaceted operations. The development of amphibious UAVs with inculcating the features of hovercraft and multi-rotor has tremendous impact on military, naval and coastal guard applications. Stability and performance of this kind of vehicle highly depend on aerodynamic interaction of multirotor with respect to various wind conditions. The present study focuses on performing computational fluid dynamic (CFD) analysis on examining the vortex formation, turbulent regimes, wake region, tip vortex formulation and ground effect.Preliminary flow analysis is performed to determine the angle of attack (AoA) and wind speed on which minimal drag is experienced by the amphibious structure. Further, analysis conducted through varying the relative velocity of the vehicle and changing the speed of the propellers. The pressure distribution across the fuselage and rotor surface predicted the stability of the vehicle. The ground effect is examined through varying the clearance between the vehicle and ground surface with respect to a multiplicity of rotor diameter. CFD analysis results suggested that at 5° AoA and 8.3 m/sec the designed amphibious vehicle yielded superior performance characteristics and stability.

Abstract:

Surf-zone environments represent an extreme challenges to robot operation. A robot that autonomously navigates rocky terrain, constantly changing underwater currents, hard-packed moist sand and loose dry sand characterizing this environment, would have significant utility in a range of defence and civilian missions. The study of animal locomotion mechanisms can elucidate specific movement principles that can be applied to address these demands. In this work, we report on the design and optimization of a biologically inspired amphibious robot for deployment and operation in an ocean beach environment. We specifically report a new design fusing a range of insectinspired passive mechanisms with active autonomous control architectures to seamlessly adapt to and traverse a range of challenging substrates both in and out of the water, and the design and construction of SeaDog, a proof-of-concept amphibious robot built for navigating rocky or sandy beaches and turbulent surf zones. The robot incorporates a layered hull and chassis design that is integrated into a waterproof Explorer Case in order to provide a large, protected payload in an easy-to-carry package. It employs a rugged drivetrain with four wheel-legs and a unique tail design and actuation strategy to aid in climbing, swimming and stabilization. Several modes of terrestrial and aquatic locomotion are suggested and tested versus range of mobility metrics, including data obtained in simulation and hardware testing. A waterproofing strategy is also tested and discussed, providing a foundation for future generations of amphibious mobile robots.

Abstract:

For amphibious vehicles that are utilized in military services, high-speed ship-to-shore movement is an important requirement for enhancement of the operational capability in tactical environments. At high speeds, such a vehicle begins to sink at the stern, causing the bow to rise out of the water. Moreover, excessive trim has a deleterious effect on forward field of vision and powering performance. In this study, a hydrofoil was considered as a trim-control device to decrease the significant bow rise without compromising the performance. Experiments were conducted in a towing tank to investigate the running attitude and powering performance of a box-shaped amphibious vehicle at high speeds. Results for the hydrodynamic features show that a fixed hydrofoil under the stern of the vehicle successfully achieved an improved trim. It was also found that the interaction between the waterjet and hydrofoil can enhance the dynamic lift of the hydrofoil.

Abstract:

AbstractOver the past century trauma care within the Royal Navy (RN) has evolved; wartime experiences and military medical research have combined to allow signifi cant improvement in the care of casualties. This article describes the key maritime and amphibious operations that have seen the Royal Navy Medical Service (RNMS) deliver high levels of support to wherever the Naval Service has deployed in the last 100 years. Key advancements in which progress has led to improved outcomes for injured personnel are highlighted – the control and treatment of blood loss, wound care, and the prevention and management of organ failure with optimal resuscitation.Historians often point out how slowly military medicine progressed for the fi rst few thousand years of its recorded history, and how quickly it has progressed in the last century. This refl ective article will show how the RNMS has been an integral part of that story, and how the lessons learnt by our predecessors have shaped our modern day doctrine surrounding trauma care.

Abstract:

Objective. The article deals with aspects of modeling the working processes occurring in marine thrusters of amphibious vehicles, taking into account the specifics of their operation. Methods. The methods of 3D modeling of propellers in CAD and CAE packages are applied, which can determine and optimize the parameters of ongoing work processes with reliable accuracy. Results. A mathematical construct is proposed that allows calculating the characteristics of marine thrusters of amphibious vehicles. The propeller is designed to provide more thrust compared to the original design, making it possible to increase the speed of movement on the water and reduce the radius of circulation when moving through the water. The calculated version of the propeller provides an increase in thrust by 36%, allows developing a high speed on the water, and significantly reduces the radius of circulation of the ferry-bridge machine when maneuvering on the water. Conclusion. The proposed option for increasing the speed and maneuverability of ferry vehicles on the water is the most effective and least expensive; a promising direction for further research to achieve maximum efficiency is the creation and verification of software, hardware, and methodological complexes for modeling the joint operation of the "marine thruster - hull - power plant" system.

Abstract:

Aiming at the problems of “local minimum” and “unreachable target” existing in the traditional artificial potential field method in path planning, an improved artificial potential field method was proposed after analyzing the fundamental causes of the above problems. The method solved the problem of local minimum by modifying the direction and influence range of the gravitational field, increasing the virtual target and evaluation function, and the problem of unreachable targets is solved by increasing gravity. In view of the change of motion state of robot fish in amphibious environments, the improved artificial potential field method was fused with a dynamic window algorithm, and a dynamic window evaluation function of the optimal path was designed on the basis of establishing the dynamic equations of land and underwater. Then, the simulation experiment was designed under the environment of Matlab2019a. Firstly, the improved and traditional artificial potential field methods were compared. The results showed that the improved artificial potential field method could solve the above two problems well, shorten the operation time and path length, and have high efficiency. Secondly, the influence of different motion modes on path planning is verified, and the result also reflects that the amphibious robot can avoid obstacles flexibly and reach the target point accurately according to its own motion ability. This paper provides a new way of path planning for the amphibious robot.

Abstract:

Multipurpose Amphibious Vehicles (MAV) and other blunt shaped floating vehicles encounter the problem of a large bow wave forming and hydrodynamic resistance at high speeds. This wave formation is accompanied by higher resistance and at a critical speed results in bow submerging or swamping. Three new shapes of hull bow design for the multipurpose amphibious vehicle were conducted at several speeds to investigate the hydrodynamic phenomena using Computational Fluid Dynamics (CFD, RANS code), which is applied by Ansys-CFX14.0 and Maxsurf. The vehicle’s hydrodynamic bow shapes were able to break up induced waves and avoid swamping. Comparative results with the vehicle fitted with U-shape, V-shape and Flat-shape of hull bow, showed that the U-shape of the hull bow has reduced the total resistance to 20.3% and 13.6% compared with the V-shape and flat shape respectively. Though, the U-shape of hull bow is capable to increase the amphibious operating life and speed of vehicle. Also it has ability to reduce the vehicle’s required power, fossil fuel consumption and wetted hull surface. On the other hand, the use of air cushions to support marine vehicles, heavy floating structures and in other operation is well known. The main problem in Multi-purpose Amphibious Vehicles (MAV) is the amount of power needed in order to overcome the hydrodynamic resistance acting on the hull which is included the frictional and pressure resistances. Therefore, more power is needed to move the MAV forward. In this respect, more fuel will be required to operate the amphibious vehicles. This problem could be effectively reduced by the introduction of the air cushion concept. With the air being drawn from top of craft to the cavity below the hull will produce some cushioning effect and also help to reduce skin friction drag. In this paper, air cushion effect will be studied in rigid surface cavity instead of using flexible skirts. This would avoid the problem of high maintenance due to replacement of damaged skirts. Finally, the MAV will be supported using air cavity and bubbles generated by an air pump (compressor and air pressure vessel) to pushes the hull of multi-purpose amphibious vehicle up and reduce the frictional resistance due to draft and wetted surface reduction and layer of air between hull surface and water. This research would be done via CFD (ANSYS-CFX 14.0) and analyzed the hydrodynamic resistance

Abstract:

Unmanned aerial vehicles (UAVs) have gained significant attention in recent times due to their suitability for a wide variety of civil, military, and societal missions. Development of an unmanned amphibious vehicle integrating the features of a multi-rotor UAV and a hovercraft is the focus of the present study. Components and subsystems of the amphibious vehicle are developed with due consideration for aerodynamic, structural, and environmental aspects. Finite element analysis (FEA) on static thrust conditions and skirt pressure are performed to evaluate the strength of the structure. For diverse wind conditions and angles of attack (AOA), computational fluid dynamic (CFD) analysis is carried out to assess the effect of drag and suitable design modification is suggested. A prototype is built with a 7 kg payload capacity and successfully tested for stable operations in flight and water-borne modes. Internet of things (IoT) based water quality measurement is performed in a typical lake and water quality is measured using pH, dissolved oxygen (DO), turbidity, and electrical conductivity (EC) sensors. The developed vehicle is expected to meet functional requirements of disaster missions catering to the water quality monitoring of large water bodies.

Abstract:

As a result of wartime research on ocean surface waves a method has been available since 1943 for the prediction of wave characteristics of interest to engineers (O'Brien and Johnson, 1947). The initial stimulus for the development came during the planning of the invasion of North Africa, and the methods subsequently devised were later used in a number of amphibious operations (Bates, 1949). The same techniques have found useful peacetime application in problems connected with coastal engineering. Much of the application to date has consisted in applying wave prediction techniques to historical rather than current meteorological data, hence the term "wave hindcasting."

Abstract:

The provision of naval gunfire support was an important aspect of the Falklands War. By the end of the 1970s, naval gunfire support appeared to be doomed, but its vital role during the Falklands War led to a timely reappraisal. Indeed, the use of naval gunfire support during the Iraq War in 2003 and the conflict in Libya in 2011 vindicated the revival of interest in the capability. The Falklands War provided a number of valuable lessons about the role and significance of naval gunfire support, particularly during amphibious and expeditionary operations. With the threat of defence cuts ever-present, it is important that those lessons are not forgotten.

Abstract:

The sharp 90°corner of bow found on American Tarawa class general amphibious assault ship LHA-1 will produce large separated region in the airwake over the ship, and the turbulence in the separation region seriously affects the operation safety of the helicopter. In order to reduce the separation in bow region of the LHA-1, and optimize the helicopter operating environment, the numerical simulation method is used to study the influence of the bow flap on the airwake of LHA-1. The study results show that: the ANSYS k-ε two equation model based on the hybrid grid can be used to predict the steady-state characteristics of the ship airwake; the bow flap can improve the flow field downwind of the flap installation position, and the impact range can cover two spots; in headwind, the optimal installation angle of the bow flap is 15°~25°. The research results of this paper can provide modification and improvement reference for the amphibious assault ship in-service and under construction, so as to achieve the purpose of optimizing the ship airwake, thereby improving the safety of helicopter landing process and extending the service life.

Abstract:

Although the traditional amphibious robot has the ability of multi-space motion, it has the disadvantage of low power utilization and no operational capability. In order to make it competent in an extremely complex environment, we studied the structural design and control of amphibian robot with operational capability. First, in order to make the robot have the ability of flying in the sky, moving on land, and swimming in the water, a “bevel variant” mechanism for power switching is designed. Then, taking the uncertainty of the kinetic parameters and external influences into account, the kinetic and kinematic models of the system are established. Next, a sliding mode controller that outputs control force for the system and a quadratic calculation optimization algorithm for inverse kinematics solution are designed. Finally, the simulation platform for the system is built based on MATLAB. The simulation results show that when the system is in the land and air flight stages, the vehicle position and orientation tracking error are within ±0.05 m and ±2°, respectively. When the system is in the underwater stage, the end effector position and orientation tracking error are within ±0.15 m and ±3.0°, respectively.
