Method of Rapid Trajectory Optimization for Missile with Morphing Swept Wings

Trajectory optimizing problem of missile with morphing swept wings was a complicated multi variable optimizing problem. To obtain the flight trajectory for missile with morphing swept wings, the radau pesudospectral method（RPM） was used to solve the flight trajectory with maximum range, satisfying both path constrains and terminal constrains. The sweep angle and attack angle was chosen as optimal con trol variables, and several strategies can ensure its realtime performance was adopted to improve the com pute efficiency. The simulation results indicate that RPM can solve the flight trajectory optimizing problem of missile with morphing swept wings quickly to satisfy the above optimization index and constraint condi tions. The results can provide a reference to the online trajectory reconfiguration of missile with morphing swept wings.
