【Abstract】 It is very important that the extended range effect is improved farthest by being master of the dynamic delay time of a rocket-portfire in the air. According to the "solid particle" theory model, a theory model of the dynamic burining velocity of a rocket portfire in its igniting delay time cannulation is established, a theory model of the dynamic delay time is educed. The factors are analyzed, setting position and shape of a igniting delay time cannulation that affect its igniting delay time.更多还原
