A coupled analysis of the UUV floating movement and the charging process of an inflatable airbag
A movement model was established to analyze the UUV (Unmanned Undersea Vehicle) movement with a positive buoyancy airbag, in which the movement is from the moment the engines shuts down to the moment when the UUV reaches the water surface.In the model, the airbag charging process and the movement process of UUV were analyzed in a coupled manner.The depth, velocity and pitch angle of the UUV when its engine shuts down and the delay time to inflate were pivotal parameters.Meanwhile, the minimum charging time, the maximum resistance of the airbag and the insurance of floating to the surface were three boundary constraints.According to the result, a concept of a floating envelop was given, which can show the influence of the design parameters to the result clearly.A mathematical method was obtained to predict the right moment to start floating, which supplied some reference to the simulation and engineering design of the UUV with an airbag-type floating device.
