摘要
可靠、安全地实现月面软着陆及月面起飞是完成月面探测任务的基本条件,也是探测器研制的一项关键技术,需要开展地面验证试验。地面环境与月面有较大的差异,探测器在地面的工作特性也与实际过程不尽相同,地面试验的设计及实施有较大的难度。分析了探测器月面着陆起飞的设计要点和地面试验的关键因素,指出了当前试验技术存在的缺陷,在此基础上提出了一种利用探测器自身动力实现月面着陆和起飞的验证方案,通过动力学仿真验证了试验实施的可行性,并对方案的拓展应用价值进行了展望,相关内容可为后续我国月球及其他行星表面探测器的研制提供借鉴。
Reliable and safe lunar landing and ascending is the basic condition for lunar exploration.It is also a key technology in the probe development,therefore ground test is required.As the environment on the ground are different from that on the moon,the operation features of the probe on the ground are also different.The design and the implement of the ground test are difficult.The design points of the lunar landing and ascending and the critical factors of the ground test are analyzed.The existing defects in current test technology are pointed out.A ground test verification scheme using the impetus of the probe itself for landing and ascending is proposed,and its feasibility is validated by the dynamic simulation.The extended application of the scheme is putted forward.The related research provides reference for the future development of Chinese lunar or planetary probes.
