Investigating the regularity and the control technology of regenerative injection process is one of the important ways to propel technology of regenerative liquid propellant gun (RLPG) forward.The principle and method of optimal control is applied to the investigation of RLPG to control the process of regenerative injection. The model of dynamic optimization of design function has been developed and applied to dynamic optimization of injection area of RLPG. This design function is resolved by means of the conjugate gradient method and the optimal routine is programmed by means of C Language.After running of this routine and computation,the optimal injection area curve and the optimal barrel pressure curve of RLPG are satisfactorily obtained.This investigation helps to improve fire performance of RLPG.
