Supercavitation sailing vehicle

Abstract

The invention provides a supercavitation sailing vehicle. The supercavitation sailing vehicle comprises a cavitator, a torpedo, an internal load, a tail control surface, a main engine and a boosting engine; the right end of the cavitator is connected with the internal load; the right end of the internal load is fixedly connected with the main engine; the right end of the main engine is fixedly connected with the boosting engine; the tail control surface is installed on the outer side of the main engine; and the torpedo is arranged in the internal load. According to the invention, the range and speed are increased by using the drag reduction characteristic of the supercavitation; conventional underwater weapons such as a light sound self-guided torpedo can be carried in the vehicle to remotely and quickly attack an enemy target; and the response time of the enemy target is shortened.

Description

technical field [0001] The invention relates to the field of underwater vehicles, in particular to a supercavitation navigation vehicle. Background technique [0002] Conventional underwater vehicles have low speed due to high resistance. Supercavitation drag reduction technology is a new principle and new way to realize high-speed navigation of underwater vehicles. The principle of drag reduction is to use Naturally or artificially, the supercavitation cladding is generated along the surface of the moving vehicle to isolate the vehicle from water, and its viscous resistance can be reduced by more than 90%, and the drag reduction effect is much higher than other drag reduction methods. [0003] Russia is in the world's leading position in the field of supercavitation weapon technology. It has developed a variety of supercavitation torpedoes with a speed of more than 150m / s and a range of 50km. However, due to the acoustic obstruction and acoustic shielding effect of the sup...

AI Technical Summary

Problems solved by technology

However, due to the acoustic obstruction and acoustic shielding effect of the supercavitating torpedo in the supercavitating flow field, as well as the strong noise generated by the engine, the torpedo cannot use the acoustic homing device, so the supercavitating torpedo generally does not have a homing system. The trajectory is pre-set, and it is impossible to track and lock the target
