Development and Experimental Analysis of Anchoring System for Asteroid Lander
摘要
Abstract
The lander is easy to rebound and flow away when landing on an asteroid.To solve this problem,an anchoring system which could anchor the lander to the surface of the asteroid is designed.The related characteristics of the asteroid constraining the design of the anchoring system are analyzed.The anchoring system is designed according to the "cord connecting mode" after analyzing the design alternatives of the anchoring system.It consists of anchoring unit,winding unit,unlocking unit,wire unit and electric/control unit.The penetration depth of the conic anchor tip is also studied.The penetrating/anchoring capability and dragging capability under microgravity of the anchoring system are tested.Experiments show that the anchoring system could penetrate/anchor in the frozen medium and drag the lander to the landing slope under microgravity environment.关键词
