At first the ballistic model of rocket projectile vertical launch is established, then it researches lift-to-drag ratio and influence of the angle of flight path on the firing range. 首先建立了***垂直发射的弹道模型,然后研究了升阻比、弹道倾角等参数的变化对***射程的影响,并分别对这两种情况进行了仿真。
Each one started with a stone ball, a good first loading can be launched to control the angle of good launch, thereby throwing the ball to each other firing halftime. 一开始每人有一个大石球,要先装填好才能发射,要控制好发射角度,将球射过对方半场。
The angle of incidence to be less than 70 ° was measured by using four light screens respectively at X and Y axis direction. The velocity, angle of incidence and coordinate of position are gained after firing. 在X和Y方向分别采用四个成固定角度的光幕来实现入射角度的测量,一次射击可得到弹丸的速度、速度方向上的空间角和着靶位置坐标。
The paper research fire angle of the projectile, firing time of the rocket motor, assisted time of the rocket motor, flying attitude of the glide phase and the terminal phase guidance law to add the projectile firing range. 在建立的模型的基础上,深入研究了炮弹的射角、火箭发动机的点火时间、火箭发动机的助推时间、滑翔段的飞行姿态以及末段制导律等对炮弹的射程及性能的影响。
The attitude angle of orientation locator for multiple launch rocket system was controlled that provided a large affection on firing dispersion. 多管火箭定向器方位角的控制对多管火箭武器射击精度的影响非常大。
