摘　　要：月球表面广泛分布着尘埃颗粒,月面探测器设计过程中需要考虑月尘的影响作用。文章提出了一套利用探测器推进系统剩余气体实现探测器器表除尘的方案,分析了喷嘴内气流的引射特性,并开展了除尘系统的原理验证试验。结果表明,喷气除尘系统构造简单、方案可行、除尘效果明显,具有较好的应用前景。The lunar surface is almost completely covered by lunar dust particles. The effect of lu- nar dust must be considered in the design of lunar lander. This paper presents a dust removal scheme which takes advantage of the remaining gas in the propulsion system of the probe. The characteristics of the ejecting flow inside the nozzle are analyzed, and the principle verification lesl of the dust removal system is performed. The results of test indicate that the dust removal system applying gas ejection is effective, simple, feasible, and has good application prospect.
