摘　　要：为研究大口径火箭增程榴弹发动机点火时刻以及助推时间对射程的影响,建立了火箭增程榴弹的质点外弹道模型,利用Matlab解算了火箭增程榴弹外弹道质心运动微分方程组。以某155 mm榴弹为算例,研究了榴弹在发动机不同点火时刻以及助推时间下的增程效果。研究结果表明:火箭发动机的点火时刻对射程影响较大,可以改变约30%的射程;助推时间对射程影响不超过5%;通过增程方案的合理选择可以实现单门炮多发弹同时弹着。In order to study the effect of the ignition and boost time of rocket motor on the range of large-caliber projectiles, the point-mass exterior ballistic model of rocket-assisted projectile is established. The group centroid differential equations of exterior ballistics of extended-range rocket projectile are solved using Matlab. Taking typical 155 mm projectile as an example, the changing regularity of range is studied by varying the ignition and boost time of rocket motor. The results show that the ignition time of the rocket motor has a great influence on the range and can change the range by about 30%. The boost time does not affect the range more than 5%. Multi-projectile coordinated attack can be achieved through the selection of the extended range solution.
