激光等离子体推力器（LPT）是一种新型的小卫星微推力器。我们报告的原型LPT的开发和测试。LPT的一些优点是：推进器电压4 V，质量小于1 kg，功率推力比10 kW/牛顿，Isp高达1000秒。寿命脉冲预计为500 N·s，典型推力水平为30 mN。预原型连续推力实验包括激光器支架和散热器、透镜支架和聚焦机构，它们耦合到靶材料传输机构。将目标材料涂在透明塑料带上，激光聚焦在带上的一系列轨道上。介绍了磁带驱动器硬件和激光驱动器电子学，以及控制和诊断软件。介绍了推力台的设计、结构和标定。在连续操作期间，排气羽流在移动带的方向上偏转。
The laser plasma thruster (LPT) is a new microthruster for small satellites. We report on development and testing of a prototype LPT. Some advantages of the LPT are: thruster voltage 4 V, mass less than 1 kg, power-to-thrust ratio 10 kW/newton and Isp up to 1000 seconds. Lifetime impulse is expected to be 500 N-s, and typical thrust level is 30 mN. The pre-prototype continuous thrust experiment includes the laser mount and heat sink, lens mounts, and focusing mechanism, which are coupled to the target material transport mechanism. The target material is applied to a transparent plastic tape, and the laser is focused on a series of tracks on the tape. The tape drive hardware and laser drive electronics, are described, as well as the control and diagnostic software. Design, construction, and calibration of the thrust stand are described. During continuous operation, the exhaust plume is deflected in the direction of the moving tape.
