HYDRAULIC POWER SUPPLY SYSTEM OF THE TEST BENCH FOR AIRCRAFT STEERING GEARS Russian patent published in 2023 - IPC F15B19/00 

FIELD: testing automatic control systems.

SUBSTANCE: experimental research of hydraulic actuators of aircraft intended for automated control of the operating pressure of the hydraulic power supply of the steering drives of aircraft. A hydraulic power supply system is proposed for a test bench for aircraft steering gears, containing a pumping unit, a tested steering gear, a fine filter, a pressure gauge, a three-position valve, a power supply, a reduction unit consisting of a pilot valve with a proportional solenoid and a feedback sensor, a poppet valve, a pressure reducing valve, consisting of a spring and a spool, a pressure sensor, a measuring and computing unit consisting of analog-to-digital and digital-to-analog converters, a personal computer in which a control signal generator and an oscilloscope are software-implemented.

EFFECT: increasing the accuracy of experimental studies and improving the reliability of taking the characteristics of the tested hydraulic products at different levels of hydraulic supply pressure, reducing the time spent on testing by automating them and expanding the possibilities for organizing fundamentally new types of experimental tests of hydraulic steering gears of aircraft.
