火箭发射过程中助推作用的研究

Study on the Boosting Effect in Rocket Launching Process

假设火箭发射过程中采用助推手段,我们计算了恒定力助推和弹簧力助推两种情况下火箭离开发射塔时的速度和经历的时间,比较了无助推情况下达到相同速度所需要的时间和飞行的高度,由此得到了助推可以节省燃料1%以上的结论.

A booster is supposed to used in rocket launching process, the velocities and the used times for rocket leaving the launching tower are calculated for the two cases of constant force boosting and spring force boosting. Comparing the time and the height to the case without the booster on the condition getting the same value of the velocities,we find that the fuel can be saved about more than one percent of the emission quality with the help of the booster.
