STAND FOR TESTING THE TORSION LINK OF THE HELICOPTER SWASHPLATE Russian patent published in 2022 - IPC B64F5/60 G01M15/02 G01M1/02 

FIELD: aviation

SUBSTANCE: invention relates to testing helicopter devices. The test stand for testing the torsion link of the helicopter swashplate contains a frame (1) with a loading device attached to it, as well as measuring instruments. The frame (1) consists of a base (2), a pedestal (3) and a rack (4), a bracket (5) is rigidly fixed on the pedestal of the frame (3), on which a hydraulic power exciter (6) is mounted, connected by an articulated rod (12) with the main rotor shaft simulator lever (17). The body (7) of the power exciter is fixed to the bracket (5), and the sliding cylinder (8) is connected to the rod (12). The rod (12) contains a force sensor (13). The rod (12) is pivotally connected to the simulator lever (17) of the main rotor shaft. The simulator (17) consists of a shaft, a block of rolling bearings, a housing, a cover and a lever. The shaft is bolted to the pedestal (3) of the frame (1). The rolling bearing block is mounted with inner rings on the shaft, and with outer rings inside the housing. The lever (16) is fixed to the body. On the rack (4) of the frame (1) there is a bracket (31), on the grooves of which the glass (29) is fixed with bolted connections.

EFFECT: ability to reproduce loads on the swashplate torsion links, which are typical for various flight modes, reduce test time and increase the accuracy of setting loads
