Description

technical field [0001] The invention relates to a data acquisition device for cavitation pressure of a high-speed underwater vehicle, belonging to the field of vehicle control. Background technique [0002] The structure of the high-speed underwater vehicle is as follows: figure 1 As shown, the flight body includes an instrument cabin 1 and a solid fuel engine 2, and the operation panel 3 is connected to the instrument cabin 1 through the operation lead wire 4; The body needs to be powered separately. [0003] Supercavitation is a physical phenomenon. When an object moves faster than 185 km / h in water, a strange large-scale water vapor groove will be formed at its tail, covering the part of the object in contact with water. The medium in contact with the object will It changes from water to water vapor. Since the density of air is only 1 / 800 of that of water, the resistance on the object can be greatly reduced, and large air bubbles will form on the surface of the object. ...
