doi:10.3969/j.issn.1000-1093.2021.06.007

Abstract

Abstract: A micro-electromechanical system (MEMS) -based micro initiation train was designed to meet the development requirements of fuze miniaturization. It is consisited of micro initiator， flyer， and MEMS safety and arming device， etc. According to GJB 5309.17—2004(K)， the detonation transfer performance of initiation train in MEMS safety and arming device was test to obtain the ideal design parameters of micro initiation train, namely， the charge desity of initiator of 1.67 g/cm³ and its charge size of 2.0 mm×1.5 mm， and the diameter and height of booster cavity in safety and arming device are 1.0-2.0 mm and 0.65-1.5 mm， respectively. The test results show the initiation train can play a role of normal explosion-proof when the thickness of the slider is less than 0.3 mm， and the function of arming can be realized under the conditions of transmitting overload of 21 000 g and rotating speed of 6 000 r/min. The primary charge and axial dimension of initiation train are effectively reduced by using the booster cavity as accelerating chamber and the flyer initiation mode.
