The Study of Fight Trajectory for Gliding Extended Range Projectile

Increasing range of a projectile with gliding flight is a quite efficient technique.The flight process of gliding extended range projectile is explained.The project ballistic model and control equations are established.The characteristics of the whole flight trajectory are studied.The result shows that the characteristics of climbing trajectory are same,while the characteristics of falling trajectory have obvious difference between gliding ballistic and ordinary ballistic.The variational rules of projectile's flight velocity along ballistic trajectory and maximal range angle show new peculiarity.The control ballistic primely achieves the project ballistic and it show that the method of control is feasible.These are important stimulative function for the design of gliding extended range projectile in the future.
