An air inlet channel of an upper-layer atmosphere air suction type electric propulsion system is designed on the basis of flowing characteristics of free molecule flow or near-free molecule flow in an upper-layer atmosphere area in the two aspects of the geometric shape and the surface material of the air inlet channel, and the air inlet channel is composed of an inlet section, a compression section, an ionization acceleration section and an outlet section; the inlet section is a cylindrical pipeline, the compression section is a contraction pipeline, the outline is a concave arc, and the left end of the compression section is tangent to the inlet section; the ionization acceleration section comprises a contraction pipeline and a cylindrical pipeline, the contour of the contraction pipeline is an outer concave arc, and the two ends of the outer concave arc are tangent to the right end of the compression section and the cylinder of the ionization acceleration section; and the outlet section is a conical expansion pipeline. And after the geometric shape design of the air inlet channel is completed, the inner surface of the air inlet channel is subjected to smoothing treatment so as to reduce the momentum/energy adaptation coefficient of interaction between gas and the inner surface, and finally the air inlet channel of the upper-layer atmosphere air suction type electric propulsion system is obtained.
一种上层大气层吸气式电推进系统的进气道，基于上层大气层区域自由分子流或近自由分子流的流动特征，同时在进气道几何外形和表面材料两个方面进行设计，进气道由入口段、压缩段、电离加速段和出口段组成；所述入口段为圆柱型管道，压缩段为收缩管道，轮廓为内凹圆弧，左端与入口段相切；电离加速段包括一段收缩管道和一段圆柱型管道，收缩管道的轮廓为外凹圆弧，所述外凹圆弧两端与所述压缩段的右端、电离加速段的圆柱相切；出口段为圆锥型扩张管道。完成进气道的几何外形设计之后，对进气道的内表面进行光滑处理，以降低气体与该内表面相互作用的动量/能量适应系数，最终获得了上层大气层吸气式电推进系统的进气道。
