发展一种新式微型喷射器,供微型卫星定向用.用多模二极管激光器产生的激光烧蚀形成推力.靶是特制的透明膜带条,激光透过透明膜,被吸收膜吸收,产生推力. 比冲达到1000s,这个值大于化学方法可达到的值,同时激光动量耦合系数达6dyne/W(6伊10-5N/W)量级. 原型机推力达到100dyne(10-3N).讨论了靶相互作用物理尧材料科学,包括制造靶和用原型机作一些测量.
Development of a new type of micro-injector for micro-satellite orientation with multi-mode diode laser laser ablation generated thrust.The target is a special transparent film strip, the laser through the transparent film, absorbed by the absorption film, resulting in thrust. The specific impulse reaches 1000 s, which is larger than the value achievable by the chemical method, and the laser momentum coupling coefficient reaches 6 dyne / W (6 × 10 -5 N / W). The prototype thrust reaches 100 dyne (10-3 N) Interaction physics Yao materials science, including the manufacture of targets and prototypes for some measurements.
