Through simulating pressure environments in the process of recovery of spacecraft and implementing the recovery controlling equipment in the loop simulation, the simulation for recovery system of lunar sample return spacecraft is a hardware-in-the-loop simulation testing system. This paper introduces the purpose of research and design, and the requirement for the recovery system of lunar sample return spacecraft. The general frame structure and design scheme, communication environment of network, running flow and new design character are summarized. Based on object-oriented technology, the parachute recovery system dynamic model is established at several separated stages, and the simulation precision is validated by measured data in the real flight tests; respond scheduling and pressure respond precision are analyzed also. The analysis result indicate that all the technology parameters conform to design target of the hardware-in-the-loop simulation testing system, and the research can provide technology support for the reliable evaluation for recovery system of lunar sample return spacecraft.
