FIELD: test equipment.
SUBSTANCE: invention relates to test benches and can be used for design and manufacture of test benches for testing hydroelectromechanical units of aircraft. Stand comprises a pump station, a hydroelectromechanical unit with a hydraulic distributor and control unit, traction, pressure gauges, safety valves, a loading device. Loading device is made in the form of a hydraulic system with a hydraulic cylinder, a proportional reduction valve, a check valve, a hydraulic accumulator and an automatic control system, which enables generation of the required linear load for a given program on the hydroelectromechanical unit under test by regulating the flow rate of the liquid through the proportional reduction valve.
EFFECT: technical result is generating the required linear load when testing hydroelectromechanical units of aircraft, high loading accuracy.
