Abstract
Lion Air JT610 and Ethiopian Airlines ET302 crashes occurred on October 2018 and March 2019 respectively. The main cause of the accident on both flights, which used Boeing 737 MAX 8 aircraft, is the defect on the Maneuvering Characteristics Augmentation System (MCAS), a new anti-stall system of this aircraft model. Boeing 737 MAX 8 is produced by Boeing Company which resides in the United States. However, passengers on both accidents could not claim compensation from Boeing Company because there is no international law that regulates aircraft manufacturer responsibilities. This research tries to analyze whether passengers can request for compensation to the United States and whether national court rulings or judgments can fill the gap in international law regarding aircraftmanufacturer. The research uses the normative juridical approach with analytical descriptive method. The research uses the library research method, focusing mainly on primary, secondary, and tertiary legal resources. This research found that the current international law could not accommodate the interests of plaintiffs to hold the United States accountable. The usage of forum non conveniens principle at the national courts made it difficult for the plaintiffs to obtain the compensation they are entitled to. Subsequently, the national law applied in each case is different which created a distinction on the compensation received by each plaintiff for the loss they suffered. Author comes into the conclusion that there is a need for the establishment of regulations in international law concerning the responsibilities of aircraft manufacturer.

Abstrak
Kecelakaan pesawat terbang Lion Air JT610 dan Ethiopian Airlines ET302 terjadi pada bulan Oktober 2018 dan Maret 2019 secara berturut-turut. Penyebab utama kecelakaan kedua penerbangan yang menggunakan pesawat terbang Boeing 737 MAX 8 ialah kerusakan sistem Maneuvering Characteristics Augmentation System (MCAS), sebuah sistem anti-stall terbaru untuk model pesawat terbang ini. Boeing 737 MAX 8 diproduksi oleh Boeing Company yang berkedudukan di Amerika Serikat. Penumpang pada kedua kecelakaan tidak dapat meminta ganti rugi pada Boeing Company karena belum adanya hukum yang dapat mewadahi penggantian rugi serta tanggung jawab manufaktur pesawat terbang dalam hukum internasional. Penelitian ini akan menganalisis apakah penumpang dapat memintakan ganti rugi kepada Amerika Serikat sebagai negara dan apakah putusan pengadilan nasional dapat mengisi kekosongan hukum internasional terkait manufaktur pesawat terbang. Penelitian dilakukan menggunakan metode pendekatan yuridis normatif dengan spesifikasi penulisan deskriptif analitis. Tahap penulisan dalam penelitian ini dilakukan menggunakan metode studi kepustakaan bahan hukum primer, sekunder, dan tersier. Hasil penelitian ini menemukan bahwa hukum internasional yang ada saat ini pun belum dapat mewadahi kepentingan penumpang sebagai penggugat untuk dapat meminta pertanggungjawaban kepada Amerika Serikat atas kesalahan manufaktur pesawat terbang. Selain itu, munculnya prinsip forum non conveniens pada level nasional mempersulit penggugat untuk mendapatkan ganti rugi pada pengadilan nasional. Hukum nasional yang diterapkan pada tiap kasus pun berbeda sehingga muncul kesenjangan mengenai ganti rugi yang diperoleh penggugat atas kerugian yang diderita. Melihat situasi ini, peneliti berkesimpulan perlunya pembentukan pengaturan dalam hukum internasional mengenai tanggung jawab manufaktur pesawat terbang.

The level of development of the aviation industry is an indicator of the scientific and technical potential of any state and also affects its economic level. This industry practically cannot exist without interaction with other countries, as technical achievements, scientific discoveries, know-how of some countries help other countries to develop the aircraft industry, as well as bring it to a new level. Manufacturers of civil aircraft interact with a large number of suppliers around the world in order to create a quality product. Using the example of Boeing-industry leader, while studying the role of suppliers and the company’s supply chain, the peculiarities of fragmentation of this company and its positive impact not only on the company’s position in the market inside and outside the country, but also on the development of the entire industry as a whole are shown.

Full textAbstract:
Evolving aircraft and engine technologies, as well as advancements in avionics, have resulted in a new generation of fighter aircraft. In order for an air force to remain survivable in such an environment it must face the necessity of either acquiring new aircraft or upgrading its fleet. Today, acquisition of new aircraft may not be an economically or politically viable solution. The newest aircraft, those with a thrust-to-weight ratio exceeding 1 to 1, generally exceed $20 million, exclusive of support costs. Politically, sale of such state-of-the-art aircraft to friendly countries may not be possible given the current FX aircraft export policy, and the fiscal posture of the country. However, there is an alternative to new aircraft acquisition, and that is functional modernization: the modernization of potentially viable systems through the implementation of new and available technologies. The Boeing Military Airplane Company and Pratt & Whitney have teamed in the newest aircraft functional modernization proposal, the F-4 Super Phantom. The full modernization package includes a new centerline conformal fuel tank, new digital avionics, and re-engining with new PW1120 engines. This paper examines the initial feasibility study conducted by Pratt & Whitney and Boeing to determine the feasibility of a functionally modernized F-4.

Recent advances in technology have completely changed people’s outlook on the world. Instant access to limitless information has revamped consumer behavior and expectations from the companies they interact with; therefore, social responsibility has become a crucial talking point in the business world as customers increasingly monitor their actions. A recent study showed that 70% of consumers want to know how brands are addressing social and environmental issues, and 46% of consumers believe it plays a decisive factor in their purchasing decision process (Duan, Hofer, & Aloysius, 2021). Even though this has its effects in every industry, this paper will focus on the aircraft manufacturer Boeing Co. Aviation is a rapid worldwide method of transportation; it is essential for modern globalization and global business as it facilitates trade and economic growth (Uniting Aviation, 2018). Given its significant impact on business and the high risks or consequences of unethical business practices, the commercial airlines production is under more scrutiny. Boeing Co. has found itself under heavy public scrutiny after two of the newly designed 737 MAX planes crashed in 2018-2019, costing the lives of over 300 passengers and crew members. To gain profits, Boeing Co. looked to upcharge commercial airlines on unconventional basic safety systems and ‘cut corners’ with regulatory agencies such as the Federal Aviation Administration by downplaying the upgrades in the new aircraft to avoid retraining and informing pilots of said new systems. In addition to this, the company fell incredibly short in its response and in its approach to addressing the incidents to the public (Peterson, 2021). This article will discuss in detail the organizational culture of Boeing Co., how their focus on economic success over ethical practices has stained their history in the aviation industry, and how the company works to overcome their unethical past for a prosperous future.

Este estudo tem como objetivo avaliar cinco métodos de previsão para demanda intermitente usando uma série histórica de consumo de peças sobressalentes da aeronave 737 Next Generation, fabricado pela Boeing, da maior frota aérea brasileira gerenciada pela VRG Airline Company S/A. Os métodos de Winter, Croston, Single Exponential Smoothing, Weight Moving Average e Método de Distribuição de Poisson foram testados em um histórico de 53 peças sobressalentes e cada uma delas possui um histórico de demanda de trinta e seis meses (janeiro de 2013 a dezembro de 2015). Os resultados mostraram que os métodos Weight Moving Average, Distribuição de Poisson e Croston apresentaram os melhores ajustes. Além disso, observou-se que a maior parte das demandas por peças sobressalentes apresentaram um padrão smooth ao contrário do resultado obtido pelo estudo de Ghobbar and Friend (2003) que apresentou um padrão lumpy. Por outro lado, tem-se que o Método de Winter apresentou-se como o de pior ajuste em ambos os estudos. Conclui-se que os métodos de Weight Moving Average e Distribuição de Poisson são os mais adequados para avaliar a demanda intermitente para o caso da VRG Airline Company S/A.

Full textAbstract:
In his Farewell Address, President Eisenhower warned that the military-industrial complex (MIC) threatened to dominate American research, crowding out commercial innovation. Ironically, a number of analysts point to spin-off benefits of the 1950s' military effort as a crucial source of American high-tech competitiveness, often citing the key example of the relationship between military jet aircraft and the Boeing's 707. But the huge military investment in jet aviation had both benefits and costs for the commercial industry. This article compares the development of the Boeing 707 and its relationship to military projects like the KC-135 tanker to the contemporary development of commercial jet aircraft by other companies that were also integral parts of the military-industrial complex (MIC), including Douglas Aircraft and its commercial DC-8 and Convair and its commercial 880 and 990. Using evidence from archives, interviews with retired company executives, contemporary trade press, and academic studies, the article concludes that membership in the MIC did not offer firms a leg up in commercial markets. President Eisenhower was generally right about the costs of the military effort, but military spending remained low enough to allow commercial industry to thrive in parallel to the defense industry.

Full textAbstract:
During the early 2000s, the Boeing Company was experiencing a market shrink due to a downturn in the aerospace industry after the 9/11 terrorist attacks, as well as severe competition from its rival Airbus. To deal with the situation and salvage its market share, Boeing proposed the design of a new aircraft called Boeing 787 or the Dreamliner. This futuristic aircraft was received very well by the airlines. Very soon, it became the fastest-selling new airplane in the history of commercial aviation. Nevertheless, after the initial successful launch, the company faced many supply-chain-related problems, which resulted in repeated delays and huge extra costs. These delays (now more than two and a half years) could add up to as long as three years. In this research, the authors investigate how the mismatch between the supply-chain capabilities and the Boeing’s strategy for developing this airplane led to these delays and extra costs.

With an overall company lifespan of only four years, Vertol Aircraft Corporation continued the tandem-rotor helicopter legacy of its predecessor, Piasecki Helicopter Corp., as well as research, development and testing of other V/STOL aircraft and technologies while concurrently designing two medium-lift transport helicopters that are still in worldwide use and/or production today. During this short timeframe, the company finalized production and deliveries of the H-21C Shawnee/V-44 for the US Army and international customers. The company designed and flew the world’s first tilt-wing VTOL, the NACA/Army/Navy/Vertol VZ-2A. Application of T53 and T58 turbine powerplants led to twin-turbine engine trials and flight tests with experimental H-21 variants. With Vertol’s in-theater customer support, the French Army and Navy introduced the H-21 into combat in Algeria which included the early use of armed, troop-carrying helicopters. The design, test and successful US and worldwide demonstrations of the privately-funded Vertol 107 led to development and certification of the 107-II airliner version and follow-on military transports as the Boeing H-46 Sea Knight. The contract to design and build the YHC-1B was won by Vertol in 1959 and led to the enduring Boeing H-47 Chinook.

The objective of the joint National Research Council of Canada (NRC) and The Boeing Company Technology Development Program (TDP) entitled 'Canadian Vertical Lift Autonomy Demonstration' (CVLAD) is to evaluate automated and supervised autonomous flight systems on NRC Bell 412 Advanced Systems Research Aircraft (ASRA) and Royal Canadian Air Force Boeing CH-147F Chinook demonstrators. Boeing technologies such as Degraded Visual Environment Pilotage System and Advanced Vehicle Management System form the foundation of an autonomy solution that aims to satisfy Royal Canadian Air Force, US Army, and other Armed Service branch end-use objectives for force multiplication, tactical advantage, pilot assistance, reduced crew operations, and enhanced fleet productivity. The Boeing Company engaged NRC under a Cooperative Research Agreement since 2016 as part of a number of strategies to upgrade Medium-Heavy Lift H-47 Chinook capabilities prior to long-term aircraft replacement in the 2030 to 2060 timeframe. A recent achievement of the CVLAD TDP by its Boeing Phantom Works, Boeing Chinook Program, Aurora Flight Sciences, and NRC Flight Research Laboratory team was the development of Automated Flight Guidance methods addressing system safety and performance. Design and evaluation activities occurred in Boeing Software-/Hardware in-loop facilities as well as on the NRC Bell 412 ASRA. The CVLAD team is using a blend of traditional Systems Engineering 'V-Shaped' Life Cycle Model, System of Systems, and Model-Based processes to develop a cyber-physical system that aims to meet end-user concept of operations and requirements. Significant benefits of virtual development tools such as component-vehicle digital twins and surrogate inflight simulation facilities are achieved as they promote effective collaboration, efficient design, and relevant verification/validation methodologies. Business models can be made more robust by phasing the introduction of technology where effective automation provides users with near-term benefits, while providing a foundation for safe, reliable, and trusted autonomous capabilities for long-term production.

Full textAbstract:
The Boeing Company has a goal of creating aircraft that are capable of continuous optimization for all flight conditions. Toward this goal we have developed morphing-capable, adaptive structures based on Shape Memory Alloy (SMA) technology that enable component and system level optimization at multiple flight conditions. The SAMPSON Smart Inlet program showed that fully integrated SMA wire bundles could provide a fighter aircraft with a Variable Engine Inlet capability. The Reconfigurable Rotor Blade program demonstrated the ability of highly robust, controlled 55-Nitinol tube actuators to twist a rotor blade in a spin stand test to optimize aerodynamic characteristics. The Variable Geometry Chevrons program, which was the first use of 60-Nitinol for a major aerospace application, included a flight test and static engine test of GE90–115B engine fitted with controlled morphing chevrons that reduced noise and increased engine efficiency. The Deployable Rotor Tab employed tube actuators to deploy and retract small fences which are capable of significantly reducing blade vortex interaction generated noise on a rotorcraft. Most recently, the Variable Geometry Fan Nozzle program has built on the VGC technology to demonstrate improved jet engine performance. The Boeing Company continues to mature SMA technology in order to develop innovative applications and support their commercialization.

Full textAbstract:
The Boeing Company has a goal of creating aircraft that are capable of continuous optimization for all flight conditions. Recent advances in SMA actuation and a detailed understanding of wing design were combined to design, build, and safely demonstrate small trailing edge flaps driven by SMA actuation. As part of a 2012 full-scale flight test program a lightweight and compact Shape Memory Alloy (SMA) rotary actuator was integrated into the hinge line of a small flap on the trailing edge of a commercial aircraft wing. This Adaptive Trailing Edge program was part of a Boeing and Federal Aviation Administration (FAA) collaboration. Aerodynamic studies of these small trailing edge flaps show that improved performance requires multiple flap configurations that vary with flight regime. Configurations include small angles of deployment for reduced fuel burn and emissions during high speed cruise and larger angles of deployment for increased lift and lower noise during takeoff and approach. SMA actuation is an ideal compact solution to position these small flaps and increase aircraft performance by simply and efficiently altering the wings aerodynamic characteristics for each flight segment. Closed loop control of the flap’s position, using the SMA actuator, was demonstrated at multiple flight conditions during flight tests. Results of the successful flight test on a 737–800 commercial airplane and the significantly improved performance benefits will be presented. This is the first flight test of an SMA rotary actuator system, which was matured from TRL 4 to TRL 7 during the program.

Full textAbstract:
Aviation industry showing significant growth around the World. Different specialization companies making partnerships with each other to make aviation imperia even bigger and more stable. The relation between companies provides not only growth but also stagnation of operations. Nowadays Boeing 737-MAX crashes prove that affected major companies were forced to stop operations, due to lack of aircraft. For that reason, ACMI (Aircraft, crew, maintenance, and insurance) companies provided the full capacity to maintain flight operations. From this perspective, ACMI companies living a golden age. These companies’ services are booked by major airlines for many months in front, due to unforeseen aircraft type grounding issues. The situation in almost every industry varies between ups and downs by forcing companies to analyze the future strategy development plan. Based on AHP (Analytic Hierarchy Process) and TOPSIS method, it is preferable to buy neither to lease an ACMI services from a longer period perspective. New aircraft are less cheap regarding maintenance schedules, fuel consumption and after full repayment, it becomes airline property. The purpose of the article is to asses ACMI company strategy development to stay in the aviation business after major airlines re-establish their full operations. The leasing company can not be a direct competitor to airlines, therefore it needs to develop specific services, which can attract customers. ACMI company can provide services as fast as possible in unexpected or emergency situations. Moreover giving the flexibility of leasing and providing extra services, makes the company be attractive and unique.

Full textAbstract:
With research and technology (R&T) development activities for the next generation SuperSonic Transport (SST) being pursued globally over the past few years, the options to proposed airframe and engine concepts appears to be converging. The United States, the Europeans, and the Japanese are all engaged in developing the technologies needed for a future SST that is environmentally compatible and economically practical. Boeing and McDonnell Douglas are part of the team under an R&T contract with the National Aeronautics and Space Administration to develop critical components and enabling materials that will allow industry to make a production decision by 2003. Europe’s three main aircraft manufacturer’s — i.e., Aerospatiale, British Aero-space, and Deutsche Aerospace — comprise the European Supersonic Research Program (ESRP). A primary Japanese effort called the Hypersonic Transport Propulsion System Research (HYPR) project consists of a consortium of four international engine manufacturers and the National Japanese Laboratory. The manufacturers are: Ishikawajima-Harima Heavy Industries Co. Ltd., the Kawasaki Heavy Industries Co. Ltd., Mitsubishi Heavy Industries Co. Ltd., and General Electric Aircraft Engines Company, USA. A recent study by the Japan Aircraft Development Corporation (Reference 1) also addressed the technology requirements for the next generation SST. There are basically three major challenges that must be met before a new SST can become a reality. They are the technical, environmental, and economic challenges. The technical challenges of the propulsion system primarily reduce the development of new materials capable of sustaining higher temperatures and vibration (high and low frequency) over longer exposure times as well as capable of being produced at reasonable costs. Low emission combustors and low exhaust jet noise are the primary environmental challenges, which are a technical challenge in themselves. The economic challenge is to produce an aircraft and propulsion system that allows the manufacturers to recover development and manufacturing costs as well as realize a reasonable Return-On-Investment (ROI). In addition, Life Cycle Costs (LCC) must not be substantially above future subsonic airliners in order to justify premium fares the public would be willing to pay for the time savings of long-distance flights and still be profitable to the airlines.

Beyond their higher specific mechanical properties, fiber reinforced polymer composites are non-magnetic, and thus do not interfere with the magnetic compass of the aircraft, making them particularly suitable for the aircraft’s skin. Recent sustainability concerns and environmental awareness has led to the popularity of natural fibers as eco-friendly reinforcements in polymer composites. Among natural fibers with established potential applications, silk fibers have recently received considerable attention from researchers due to their remarkable properties. Strong, lightweight and flexible, silk is a viable natural reinforcement that can be repurposed for composite industrial use. However, silk composite laminates are hardly used in aerospace products due, in part, to a lack of affinity between the silk fibers and epoxy, the polymeric resin often used to manufacture silk composites. This paper investigates the effect of polymer/fiber affinity on the performance of silk composite laminates. To this effect, the silk/resin contact angle is measured for different resins, and correlated with the mechanical properties of the silk composite laminates fabricated by vacuum assisted resin transfer molding (VARTM). The ability of the resin to impregnate the woven silk fiber preform is observed to affect the mechanical performance of these laminates as well as their overall quality.

The General Electric LM5000 Marine Gas Turbine (see figure 1) intended for application to commercial and naval ships requiring high power (50,000 BHP nominal), high thermal efficiency (38 percent), and compact, marinized and relatively light weight prime movers is described. Ship candidates include Fast Support Ships, Aircraft Carriers [in a Combined Nuclear and Gas Turbine (CONAG) propulsion system], Battleships and large surface effect ships. The LM5000 marine gas turbine is a marinized version of the LM5000 industrial gas turbine which was derived in 1977 from the CF6-50 aircraft engine. The CF6-6 model of this family of aircraft engines was the parent of the over 648 GE LM2500 marine gas turbine now used on the ships of 18 navies, 32 ship programs and 247 ships of the world. Over 2100 of the CF6-50 mode] engines are used on over 600 of the McDonald Douglas DC-10, the Airbus A300 and the Boeing 747 aircraft. Since reliability and durability are dependent upon engine family experience, the hardware commonality with the CF6-50 aircraft engine is described as well as the associated experience, performance, installation and maintainability features.

This paper describes the development and flight testing of a personal air vehicle by team Harmony for the Boeing GoFly X-prize challenge. For the $1mil grand prize, aircraft were scored by compact size, speed, low noise, and endurance. The team chose a coaxial electric helicopter configuration to maximize rotor area and reduce disk loading for efficiency and acoustic benefits. The rotors were designed through an extensive parametric study using an in-house performance code. Air loads were modeled in HPCMP CREATE™-AV Helios for validation, then used in an inhouse acoustics solver to estimate sound pressure levels. A quiet electric power train was developed, as well as a custom 11kWh, 200lb (90.7kg) battery pack. The flight dynamics of the configuration were modeled and the stability analyzed. Structural analysis was utilized in designing key load-bearing parts. Flight control was implemented with dual, independent, electronically coupled swashplates. First, a 1/3rd scale prototype aircraft was developed to validate the design and acoustic predictions. Then a full-scale, 520lb (235.4kg) prototype with an 8.5ft (2.59m) rotor diameter was developed and accumulated 19.5hrs of testing time. During hovering, the sound pressure levels at 50ft (15.24m) were 73dBA, remarkably low for a rotorcraft. The results of this study underscored the endurance limitation of electric flight due to poor battery performance, as well as the need for reliable, lightweight hardware for such applications.

Abstract Efficient and affordable multidisciplinary thermal management technologies are becoming increasingly important in emerging aviation, power, and electronics cooling applications. High performance compact thermal devices are needed for existing and emerging aerospace systems, which include commercial / military, hybrid-electric, urban air mobility and high-speed air vehicles, among others. Advances in additive manufacturing (AM), materials, and design processes play a critical role in development of next-generation AM-enabled heat exchanger technology. This paper reports recent Boeing-led breakthrough advances in thin-wall (150–175 microns) metallic AM and its use in conformal heat exchangers and cold plates for aircraft engine precooler and electronic cooling applications, respectively. A model based engineering (MBE) approach is used in developing highly efficient AM heat exchanger designs. Their performance benefits are validated using a complimentary numerical simulation and experimental performance measurement method. The measured heat exchanger effectiveness and pressure drop in AM-produced brick-shaped and conformal heat exchangers are in good agreement with model predictions, within ∼5% and 20%, respectively. An overview of steps required for achieving technical maturity and production readiness of metal AM heat exchanger and cold plate technology, along with an envisioned roadmap for adoption of this technology in aviation platforms, is presented.
