Study on ballistic models of rocket-aid gliding extended projectiles

The flight theory of rocket-aid gliding extended range projectiles is explained. The whole trajectory is divided into three parts for analysis. First, a projectile rises freely; then when it get nearby the top of the trajectory, it glides at horizon direction by the control of helms; at last, it glides to the termination taking the parameters when the horizon gliding ends as its initial parameters. Under the assumptions with very little changes of velocity in horizon gliding phase and very little angle of attack, the gliding ballistic models are established and by computer simulation, the ballistic curve and the flight velocity changing curve along the whole trajectory of gliding extended range projectiles are gained. The results have referrence value for ballistic design of gliding extended projectiles.
