一、问题的提出飞航式导弹为了防止敌方的拦截,一般在低空巡航。由于低空空气密度大,导弹阻力大,要保持一定的巡航速度,发动机须提供大推力,因此燃料消耗就多,这样导弹的射程将受到限制。至于超音速的飞航式导弹,它的低空突防能力很强,即使在高空巡航然后俯冲至低空捕捉目标也有一定的生存力。因此同一飞航式导弹,为了扩展防域,攻击更远的目标(舰艇或地面目标),利用高空空气密度小,导弹阻力小和在同样的巡航速度下,发动机耗油少的优点来扩大射程。在一定的高度范围内(此范围内,发动机均可正常工作),消耗同样多的燃料,存在着一条最优的弹道,这条弹道使导弹的射程为最大。本文就这一问题作了初步探讨,并
First, the issue put forward In order to prevent the enemy's missile-based missile interception, cruise at low altitude. Due to the density of low-level air and the large resistance of the missile, to maintain a certain cruising speed, the engine must provide a large thrust so the fuel consumption is much larger, so that the missile's range will be limited. As for the supersonic flight missiles, its low penetration ability is very strong, even when cruising at high altitude and then diving to capture targets at low altitude has a certain degree of viability. Therefore, for the same flying missile, in order to expand its defense and attack targets (naval vessels or ground targets), the same missile cruise missile will be used to expand its range by using the advantages of low altitude air density, small missile resistance and low fuel consumption at the same cruising speed . Over a range of altitudes (where the engine works properly), consuming the same amount of fuel, there is an optimal trajectory that maximizes the missile's range. This article made a preliminary discussion on this issue, and
