DEVICE FOR TEST STRENGTH OF FLAP OF AIRCRAFT Russian patent published in 1994 - IPC

Abstract SU 1607558 A1

FIELD: aviation. SUBSTANCE: decrease of effect of weight of level system simulating aerodynamic load on tested flap and increased authenticity of tests due to it are provided by installation of balancing mechanism composed of links 9 and 10, 11 and 12, 13 and 14 forming two rhombs on axle around which lever system and tested flap turn. Value B of one of rhombs of hinged to lever system 8 and is placed in center of its mass. Weight 15 balancing system 8 is suspended from vertex C of the other rhomb. EFFECT: making conditions of tests closer to real ones. 2 dwg
