Abstract

The invention provides a suspending falling testing device used for rocket recovery and relates to a suspending falling testing device to solve a problem that an existing rocket landing supporting mechanism is lack of a device for simulating the motion of the landing supporting mechanism to verify the reliability of each component of the landing supporting mechanism. The suspending falling testingdevice used for rocket recovery comprises a bracket, a diagonal tension releasing mechanism, a connecting plate, a diagonal tension steel wire rope, a horizontal projection releasing mechanism and atraction steel wire rope; one end of the diagonal tension steel wire rope is connected with the bracket; the other end of the diagonal tension steel wire rope is connected with the diagonal tension releasing mechanism; the diagonal tension releasing mechanism is hinged to the connecting plate; the connecting plate is connected with the bracket through the traction steel wire rope; the horizontal projection releasing mechanism is arranged on the connecting plate; the horizontal projection releasing mechanism is connected with the landing supporting mechanism; and the traction steel wire rope and the diagonal tension steel wire rope are arranged to have a certain angle between each other so that the landing supporting mechanism is suspended in the air. The suspending falling testing device used for rocket recovery is suitable for simulating the motion of the landing supporting mechanism on a rocket to verify the reliability of each component on the landing supporting 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...
