摘要:利用天平原理设计了微推力测试装置，经标定，该装置可以测量的最小推力为5×10-5N。测试了装有以硝酸肼镍为主要成分的微化学推力器的推力，其药室直径为1.0mm和1.5mm，药室高度分别为1.5mm和3.0mm。测试结果表明，该装置测得的最小推力为3×10-4 N，可以满足微推力测试要求。
Abstract:Based on the principle of balance, the equipment for determining the micro thrust was designed. It can measure the minimum thrust of 5×10-5N. The thrust of micro-chemical thrusters (MCTs) charged with nickel hydrazine nitrite was tested. The chamber diameter of the MCTs is 1.0mm and 1.5mm, and the responding height is 1.5mm and 3.0mm respectively. The results showed that the minimum micro-thrust of the MCTs is 3×10-4 N, and such equipment can meet the requirement of the micro thrust testing.
