摘要
对以气球喷气为动力的小车运动状态进行研究,从气球内部的压强入手,综合考虑摩擦力,对气球车的效率进行定义和研究,探究了小车效率的影响因素,并结合实验进行了合理的理论修正,确定了最大效率的范围.
Starting from the internal pressure of the balloon and considering friction comprehensively, this arti- cle does research on the state of motion of balloons jet-powered car. We define and study the efficiency of the bal- loon car to explore influencing factors of the efficiency of the car. At last we combine with experiments and use rea- sonable theory correction to determine the range of maximum efficiency.
