FULL-SCALE TEST RIG FOR TESTING FLYING VEHICLES Russian patent published in 2000 - IPC

FIELD: aviation. SUBSTANCE: test rig includes base and unit for suspending the flying vehicle to be tested above base. This unit is made in form of support whose one end is secured to base and other end is connected with center portion of lever by means of single-degree-of- freedom joint. Flying vehicle is mounted in frame embracing it over perimeter in horizontal plane for swinging in vertical plane around horizontal axis perpendicular to plane of symmetry of flying vehicle. Frame is secured on ends of clamp by means of second pair of trunnions for swinging around longitudinal axis of flying vehicle. Clamp is secured on one end of above-mentioned lever by means of flexible coupling located on vertical axis of flying vehicle running through center of gravity. Secured on other end of this lever is weight which is used for balancing the lever with clamp and frame secured on it. Articulated on support is safety stop which is kinematically or electromechanically linked with frame, clamp and flying vehicle; this stop is used for limiting angle of lever swinging. EFFECT: enhanced efficiency. 2 cl, 2 dwg
