Research on resistance characteristics of multifunction remote unmaned under-water vehicle
Aiming at the requirements of safety and efficient for deep-sea target detection and salvage operations,a multi-functional remote unmaned underwater vehicle with vector configuration of multiple propulsion systems was proposed in this paper.According to the configuration and operation performance parameters of the vehicle,the characteristics of con-tour resistance and umbilical cable resistance under various working conditions were firstly analyzed and calculated by hy-drodynamic method.Through the horizontal surface multi-propeller ring vector configuration and vertical surface propeller symmetrical distribution configuration,the vertical and horizontal surface movements were decoupled to achieve efficient multi-degree-of-freedom movement of the vehicle.Then,according to the performance of the propeller and the calculation and analysis of the vehicle resistance characteristics under different working conditions,the relationship curve of resistance,power and speed was fitted to verify the rationality of the propulsion system configuration.Finally,the resistance character-istics and the thrust output characteristics of the propeller were compared and analyzed.The results show that the power con-figuration mode and the thrust efficiency of the vehicle meet the requirements of the maneuvering operation performance of the UUV.
