| Abstract: | In order to realize long range flight of a cruise ramjet guided projectile with an extended range, this paper studies the multi stage ballistic planning adapted to its flight characteristics. A mathematical model is established according to its long distance flight characteristics, which divides the flight process of the projectile into three stages, including climbing, cruising and diving attack. In order to ensure the stability of climbing, the altitude command of an exponential function is adopted in the climbing stage, and the selection basis of relevant parameters is given according to the ballistic characteristics. In the flat flight section, the altitude command is used for ballistic design, which issues control instructions for ballistic tracking through PD control. The proportional guidance method is adopted in the attack section to ensure the accuracy of the attack. The simulation results show that the designed trajectory can meet the flight characteristics of the cruise ramjet guided projectile with an extended range, and achieve long range flight and precise strike. |
