Embodiment Construction
[0039] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0040] Such as figure 1 Shown, a kind of generation method of the impact prediction model of rocket wreckage, described method comprises:
[0041] Step S1) establishing the dynamic equation of booster wreckage flight;
[0042] After the booster wreckage is separated from the arrow-ship complex, it is in an uncontrolled flight state under the action of the earth’s gravity, air resistance, wind force and earth rotation. Let the coordinates of the booster wreckage in the launch system be (x, y, z ), the velocity is (V x ,V y ,V z ), where the projection of the high-altitude wind in the launch coordinate system is: (w x ,0,w z ), then the dynamic equations of the wreckage are:
[0043] sin θ = ...
