Application of hydraulic pressure in aerospace field

The application of hydraulics in aerospace field includes hydraulic system and hydraulic steering gear system.

Hydraulic system is a kind of mechanical transmission system widely used in aerospace field, which realizes force transmission and control through the transmission ability of hydraulic oil. Hydraulic steering gear system is one of the key components to control the rudder angle and fuselage attitude in spacecraft. The motion of the rudder surface is controlled by the pressure and flow of hydraulic oil, so as to realize the attitude adjustment and course control of the spacecraft.
