基于弹跳原理设计并制造了小型燃气驱动弹跳器.根据燃烧热动力学分析,通过迭代计算得到燃烧室内点燃后的气体压力与缸体位移之间的关系曲线,由此计算出高压气体作用在缸体上的功,最后得到弹跳机构的初始弹跳速度.同时,开发了无线控制系统,实现弹跳器的无线遥控.实验结果与理论计算结果相吻合,弹跳机构可以达到高度2.2 m、距离3.5 m的弹跳性能,是其自身尺寸的14倍以上.

Based on the hopping principle, a miniature gas fuel-powered hopper is designed and manufactured. According to thermodynamic analysis, the pressure-displacement curve in the combustion chamber after ignition is obtained through iterative calculation, then the work on the cylinder done by high-pressure gas is calculated and the initial hopping velocity of the hopper is obtained. The wireless control system is developed to realize the tele-control of the hopper, including fuel injection and ignition. Experimental results agree well with analytical results. The hopper has a jumping ability of height 2.2 m and distance 3.5 m, and it is more than 14 times its dimension.
