Abstract
|
Power controlled warhead by controlling the warhead main in charge of the explosive combustion percentage in order to control different power output, demand to adapt to the different field. Power control mechanism of warhead has a broad application prospect, can be applied to large to small missile to grenade all ammunition system. Power controlled warhead when applied to kill bombs can realize control range, realize accurate damage. This paper mainly studies based on the explosive combustion to detonation mechanism of power controlled warhead, describes the explosive combustion was established based on reasonable assumptions turn the detonation process of one dimensional two phase flow model; Based on the experience of shock wave overpressure calculation formula was derived around burning detonation of explosive shock wave overpressure formula; Based on Lee - the AUTODYN Tarver - 2 d software was studied ignition strength, detonation mode, constraints, strength and loading conditions on the influence law of 8701 explosive combustion to detonation process, how to control around burning detonation of explosive detonation induced distance (the percentage of explosive combustion) to make a certain exploration; Finally, through the experiment, confirmed the 8701 explosives under certain conditions can combustion to detonation, and got 8701 explosive combustion ignition strength of the induced detonation distance in the process of detonation.
