The proposed area of study is the complex and non-linear fluid dynamic interactions which occur between an ex- panding jet emitted from a spacecraft retro-propulsion rocket nozzle and the surface of a planetary body during a soft landing procedure, termed Plume Surface Interactions (PSI). The work will focus on the development and evaluation of a method of mitigating negative plume- surface effects by leveraging secondary flow to capture regolith ejecta, and simultaneously using supersonic fluidic injector technology to minimise plume-driven surface alteration. Unique to this proposal is the intended realisation of these goals using only spacecraft-borne hardware

拟议的研究领域是在软着陆过程中从航天器反向推进火箭喷嘴发射的膨胀射流与行星体表面之间发生的复杂且非线性的流体动力相互作用，称为羽流表面相互作用（Plume Surface Interactions）。 PSI）。这项工作将重点开发和评估一种方法，通过利用二次流捕获风化层喷射物，同时使用超音速流体喷射技术来最大限度地减少羽流驱动的表面蚀变，从而减轻羽流表面的负面影响。该提案的独特之处在于仅使用航天器搭载的硬件来实现这些目标
