Abstract

A suspension drop test device for rocket recovery, which relates to a suspension drop test device to solve the lack of existing rocket landing support mechanism to simulate the movement of the landing support mechanism to verify the reliability of the components of the landing support mechanism device problem. The invention comprises a bracket, a cable-stayed release mechanism, a connecting plate, a cable-stayed steel wire rope, a flat throw release mechanism and a traction steel wire rope; one end of the cable-stayed steel wire rope is connected to the bracket, and the other end of the cable-stayed steel rope is connected to the cable-stayed release mechanism, and the cable-stayed release mechanism The mechanism is hinged with the connecting plate, the connecting plate is connected with the bracket through the traction wire rope, and the flat throwing release mechanism is arranged on the connecting plate, and the flat throwing release mechanism is connected with the landing support mechanism. up in the air. The invention is suitable for simulating the motion of the landing support mechanism on the rocket to verify the reliability of each component on the landing support mechanism.

Description

technical field [0001] The invention relates to a suspended falling body testing device, in particular to a suspended falling body testing device used for rocket recovery. Background technique [0002] The prospect of commercial aerospace development is promising. With the integration of military and civilians, my country has accelerated the development of private aerospace. At present, most of the launch rockets are for one-time use. Recycling rockets through development is a powerful way to reduce launch costs, and the rocket landing support mechanism is As one of the key technologies of recoverable rockets, designing a landing support mechanism with high reliability is the premise and guarantee for completing the recovery work. After the development of the rocket landing support mechanism is completed, it is necessary to accumulate launch data through ground tests and verify the reliability of component selection. At present, there is no device that can simulate the movem...
