Abstract:

The dynamic behavior of and the vibration in supercavitating underwater vehicles are here investigated and controlled. Supercavitating vehicles exploit supercavitation as a means to reduce drag and increase their underwater speed. The forces acting on supercavitating vehicles are completely different from those on conventional submerged bodies, since only a tiny percentage of their external surface area is wetted and water-vapor forces are almost negligible. The hydrodynamic stability of supercavitating bodies is achieved through after-body planing, or surfing, along the internal surface of th

Abstract:

Traditional underwater vehicles are limited in speed due to dramatic friction drag on the hull. Supercavitating vehicles exploit supercavitation as a means to reduce drag and increase their underwater speed. Compared with fully wetted vehicles, the non-linearity in the modelling of cavitator, fin and in particular the planing force make the control design of supercavitating vehicles more challenging. Dominant non-linearities associated with planing force are taken into account in the model of supercavitating vehicles in this paper. Two controllers are proposed to realize stable system dynamics

Abstract:

A calculation method was developed to predict motion of supercavitation vehicles based on the computational fluid dynamics (CFD) model. Control equation of supercavitating flow and motion equations of vehicles are coupling solved through self-made software. This method can directly obtain hydrodynamic data of the vehicle and accurately predict instantaneous motion attitude and trajectory of the vehicle. The simulation results of a supercavitation vehicle motion process show that this method can predict interaction between vehicle and cavity surface and periodic tail beat phenomenon, which acco

Abstract:

Supercavitating vehicle utilizes supercavity to reduce the drag force when travelling underwater. It could achieve a speed higher than 200Kn. The dynamic equations of supercavitating vehicle in the vertical plane were studied and the forces are analyzed in detail in this study. Three possible balanced states and configurations are analyzed. Considering the deviation of mass center during the flight, trajectories of uncontrolled supercavitating flight with these configurations are calculated respectively. Results show that fin position and the deviation of center of mass are main factors that a

Abstract:

A high-speed supercavitating vehicle is a future underwater vehicle which exploits the supercavitating propulsion technology providing a promising way to increase the vehicle speed. Robust control challenges include complex vehicle maneuvering dynamics caused by factors such as undesired switching, delayed state dependency, and nonlinearities. As effective and applicable controllers, a novel fractional-order sliding mode controller is proposed to robustly control the uncertain high-speed supercavitating vehicle system against external disturbances. The control scheme uses sliding mode control

Abstract:

During last decades, many investigations have been done to find suitable solutions to reduce the drag force of underwater vehicles. These attempts can be divided into two main categories: supercavitating vehicles and unseparated flow patterns. In this study, a novel approach is introduced which uses hydrophobic surfaces for an underwater vehicle with an unseparated flow body profile. Fluid slippage on hydrophobic walls can lead to a considerable reduction of skin friction drag. The effectiveness of this approach for underwater hulls has been examined numerically. In this regard, first, the num

Abstract:

A finite element model for supercavitating underwater vehicles is developed considering the effects of the connection surfaces of cabins and the non-structural mass distribution on the structural dynamic characteristics. The frequency response of supercavitating underwater vehicles is investigated, and the performance of the configuration with flanged connections is compared to those of the configuration with sleeve connections. The flanged and sleeve configurations are then optimized while minimizing the mass of the shells and the centre-of-gravity coordinate in the axial direction respective

Abstract:

Supercavity can increase speed of underwater vehicles greatly. However, external interferences always lead to instability of vehicles. This paper focuses on robustness of supercavitating vehicles. Based on a 4-dimensional dynamic model, the existence of multistability is verified in supercavitating system through simulation, and the robustness of vehicles varying with parameters is analyzed by basins of attraction. Results of the research disclose that the supercavitating system has three stable states in some regions of parameters space, namely, stable, periodic, and chaotic states, while in
