| Abstract: | The structure of the deployable and lockable soft-landing mechanism for Apollo detector is complex and not reliable.To overcome the disadvantages,a new deployable and lockable soft-landing mechanism for planetary probes is developed.The compressing,deploying and locking devices of the new mechanism share a set of mechanism,and the new mechanism has the advantages of steady deploying,simple construction and high reliability.The deployment and locking theory of the new mechanism is introduced.Then,the singula... |
