AI Technical Summary
Existing underwater vehicles use propeller thrusters that cause vortices that affect the living environment, have low energy utilization efficiency, and pose a risk of collision under harsh conditions. In addition, low-speed maneuvering and fine control increase navigation resistance.
A simple underwater jet generator is used, which uses a vibrating diaphragm to compress or expand the volume in the gas holding chamber. Combined with a guide baffle and multiple jet outlets, it realizes alternating gas-liquid operation and improves the jet intensity and speed.
On the basis of reducing energy consumption, the jet intensity and speed are improved, the propulsion efficiency and maneuverability of underwater vehicles are enhanced, and the impact on the living environment is reduced.
