A new method of optimal design on terminal trajectory correction projectile

In order to solve the complicated problem of parameter design for terminal trajectory correction projectiles (shorten as TTCP), establishing the six degree of freedom ballistic model of TTCP, some analysis about the influencing factors of TTCP was performed, including starting point of the impulse, the value of single impulse, the rolling velocity, the quantity of impulse motors, the impulse duration and the multiimpulses ignition mode etc. The mathematics model of parameter optimal design for TTCP was established by study on the analysis, and a new optimal method shorten as MPSO which was presented to optimal design the ballistic parameters of TTCP based on self-adaptive punitive function. Simulation results indicate that the new method has perfect optimal ability and strong robustness, the method verified can be well in parameter design for trajectory correction projectiles by theoretical argument.
