Research of the Possibility of Reducing the Weight of Aircraft Onboard Hydraulic System by Application of the Principle of Pressure Boosting at Failure

In this article explores the possibility of reducing the mass of aircraft’s hydraulic system by a pressure adaptive system. As initial data, the hydraulic system of a promising front-line bomber considered. The determination of the mass of aircraft’s hydraulic system based on the loads perceived by the actuators of the aircraft’s control system, various levels of pressure in the hydraulic system, as well as the force margin of the power actuators of aircraft’s control system. In course of this exploration was made a comparison between of masses of the units of the system with excessive force drivers and the masses of the units of a pressure adaptive hydraulic system. As the result of this comparison, it was found that the use of a pressure-adaptive system can reduce the mass of the designed hydraulic system in the range from 8 to 22,5%.
