【摘要】 该文用优化设计方法分析了分段推力火箭发动机的增程特性,指出分段推力方案特别适合于射程为30 km以上的中远程野战火箭弹,其增程幅度在20％左右,同时火箭弹的密集度也能得到改善。若保持射程一定,则可相应减少装药量或降低对推进剂的能量指标要求。更多还原

【Abstract】 This paper analysed the range increase characteristics ofthe step thrusts rocket engines by means of the optimum designmethod. The step thrusts programme is especially suitable to themedium and long range rocket projectiles, which have a range morethan 30 km, with the range increasing about twenty percent. At thesame time,the dispersion of rocket projectile will also be decreased. Ifthe range remains certain,the propellant charge can be decreased orthe energy level of the propellant may be lowered.更多还原
