摘　　要：传统的直接侧向力一般是由燃气发生器提供,在国内由燃气瓶提供侧向力有很多缺点,并且极易造成爆炸,容易干扰航天器的电磁信号的收发。所以本文尝试采用小型气瓶提供侧向力,对比了负载为直孔、节流片和拉瓦尔喷管的情况下侧向力的大小以及氮气和氩气的供气时间。结果表明,拉瓦尔喷管由于其特殊结构,起到显著增加侧向力的作用;在相同负载的前提下,氩气的供气时间比氮气的有所增加。Direct lateral force is usually provided by a gas-powered engine. In the domestic, gas bottle generating lateral forces has many shortcomings, and is apt to explode, can easily interfere with the electromagnetic signals transceivers of the spacecraft, so the paper tries using a small cylinder to provide the lateral force, and compares with the lateral force of straight holes, cutting pieces and laval nozzle, and also compares the working hours of the nitrogen and argon. The results show that, laval nozzle plays a significant role to increase the lateral force as its special structure; the working hours of argon are longer than the nitrogen under the same load condition.
