TEST STAND FOR CONDUCTING ENDURANCE TESTS OF FLYING VEHICLE LANDING GEAR

摘要

FIELD: tests stands for conducting tests of full-scale undercarriages of flying vehicles. SUBSTANCE: proposed test stand includes drive with flywheel and several loading passages; each passage has pipe line with force-forming hydraulic cylinder whose one end is articulated on immovable base and other end is articulated with fixed undercarriage. Each loading passage is provided with crank and power hydraulic cylinder whose cavity is connected with cavity of force-forming hydraulic cylinder by means of pipe line; piston of power hydraulic cylinder is connected with crank which is linked with drive common for several loading passages. Drive is provided with flywheel. Each passage may be provided with additional hydraulic cylinder whose cavity is communicated with cavities of power and force forming cylinders through cocks; piston of additional hydraulic cylinder is connected with one end of flexible member of varying rigidity; its other end is secured immovably. EFFECT: reduced labor consumption and time for conducting tests. 5 cl, 4 dwg
