论文摘要
报道了为近太空环境设计的亚大气射频引擎（肯定）的概念。天线包裹石英管由两个具有可变分离距离的螺线管线圈组成，并由射频电源（13.56〜MHz-1〜kW）驱动。放电涉及每个螺线管线圈下的电感耦合以及它们之间的电容耦合。这种新颖的方案可以在近空间中的整个压力范围内有效地将填充空气电离。形成的血浆密度和温度分别为2.23 \ times 10^{18} 〜m^{ - 3}和2.79 eV。详细介绍了分离距离，输入功率，填充压力和螺线管转弯数量的影响。这种空气呼吸的电推进系统没有面向等离子体的电极，也不需要外部磁场，因此耐用且在结构上紧凑和光线。
A concept of SUb-atmospheric Radio-frequency Engine (SURE) designed for near space environment is reported. The antenna wrapping quartz tube consists of two solenoid coils with variable separation distance, and is driven by radio-frequency power supply (13.56~MHz-1~kW). The discharge involves inductive coupling under each solenoid coil and capacitive coupling between them. This novel scheme can ionize the filling air efficiently for the entire pressure range of 32\sim 5332 Pa in near space. The formed plasma density and temperature are up to 2.23\times 10^{18}~m^{-3} and 2.79 eV, respectively. The influences of separation distance, input power, filling pressure and the number of solenoid turns on discharge are presented in detail. This air-breathing electric propulsion system has no plasma-facing electrode and does not require external magnetic field, and is thereby durable and structurally compact and light.
