STAND FOR STRENGTH TESTS OF AIRCRAFT STRUCTURES

摘要

FIELD: test equipment.;SUBSTANCE: invention relates to the field of test equipment, in particular, to the aircraft structures strength testing devices. Device comprises an automated control system, an oil pump station, which includes a supply tank, system of pipelines, high-pressure pumps, loading system including servo drives, sensors, pressure and discharge manifolds. Device providing additional capacity for creation of peak loads, contains high-pressure controlled pump, which suction pipeline is connected to drain manifold, and delivery pipeline is connected to loading system discharge manifold, wherein pump control is performed from automatic control system according to preset program.;EFFECT: technical result consists in reduction of test time, increase in accuracy of reproduction of loads on structure and simplification of test bench operation.;1 cl, 1 dwg
