Selection of design parameters of the system for changing the supply of power supplies for hydraulic systems of aircraft

The article develops a mathematical model of the variable flow pump aircraft power supply, designed to simulate operation supply depending on speed sustainer engine, oil temperature, pressure and (removable power). In addition, control algorithm has been developed that provides required quality transient process, which is achieved by installing additional hydraulic resistances between servo piston cavity, drain line spool, change characteristic contribute fastest attenuation process reduce its oscillation.
