Chang＇E-3 probe incorporates four landing gears to assure the soft-landing,which are stowed while launching and deployed after separated from rocket. Deployment reliability is quite crucial for this mission. The deployment reliability test（ DRT） method and assessment method were developed in this paper. Then DRT was conducted and the deployment reliability estimate of Chang＇E-3probe was used to verify the proposed methods. 相似文献
