METHOD OF TESTING FLYING VEHICLES FOR STRENGTH AND DEVICE FOR REALIZATION OF THIS METHOD

摘要

FIELD: test stands for testing flying vehicles for strength. SUBSTANCE: proposed method consists in subjecting the flying vehicle to periodic alternating loads by feeding the working fluid to hydraulic force exciters of flying vehicle under test from pumping station through main pipe lines followed by measurement of load thus obtained with the aid of force sensors connected with program unit controlling the procedure of delivery of working fluid to hydraulic force exciters. Magnitude of load is regulated by amount of fluid fed to hydraulic force exciters made in form of hydraulic reservoirs with holes in upper portion; rates of increase and decrease of load are regulated through throttling the fluid by means of adjustable throttle valves and drainage of fluid; control of delivery of working fluid to hydraulic force exciters is effected by means of two-way distributors fitted in delivery lines and by drainage of working fluid; control is effected by means of program unit. Excessive fluid escaping from hydraulic reservoirs through holes found in their upper portion is received by tray connected with pumping station by means of return line. Invention gives description of device proposed for realization of this method. EFFECT: enhanced efficiency and reliability. 3 cl, 1 dwg
