Motion Simulation Analysis of Blended-Wing-Body Underwater Glider

In view of the weak gliding ability of the underwater glider with a rotation-body shape in shallow waters, the blended-wing-body underwater glider is taken as the research object to establish its vertical plane dynamics model, and MATLAB/Simulink is used to build the motion model simulation system to study the open-loop motion response. The influence of the actuator regulation speed and buoyancy regulation mechanism layout on the motion performance of underwater glider is analyzed, and a solution for glide operation in shallow waters is obtained. The influence degree and quantitative relationship of underwater glider system input on the motion response parameters are studied. The relationship between glide ratio and motion angle of blended-wing-body underwater glider is analyzed. It is concluded that the small angle glide can take full advantage of the large glide ratio to adapt to the glide operation in shallow waters.
