SUSPENSION RELEASE DEVICE FOR OBSERVING LANDER DROP POSTURE CHANGES AND TEST METHOD

WIPO Patent Application WO/2021/227626

A1

Disclosed are a suspension release device for observing lander drop posture changes and a test method, belonging to the field of space exploration. The device comprises a rack system, a lifting system, a horizontal frame system, a posture control system and a suspension release system, wherein the lifting system is fixed on the rack system, the horizontal frame system can vertically slide on the rack system and can drive the posture control system to horizontally slide, and the suspension release system is hinged to the posture control system. A test lander is fixed to a release sliding block, the release sliding block and a main force bearing block are locked, the posture during release is adjusted, the horizontal frame system is lifted to a preset height, an electric motor indirectly drives a guide rod to release the sliding block, the whole machine freely falls and collides with the ground, and a high-speed camera records the process. The present invention avoids the shaking caused by rope suspension and the uncertainty of the posture during release before the release of a complete machine drop test, such that the body posture before the lander touches the ground can be simulated to a greater extent.
