摘要:针对现代武器弹药中火工品微型化的问题,提出了一种内置MEMS隔断机构的微起爆装置,采用MEMS工艺进行制备,其中隔断机构为电热执行器驱动,起爆器为Al/CuO含能复合薄膜的镍铬合金起爆桥。经测试隔断机构在11V电压驱动下能够较好地实现双向位移,位移距离为1mm,起爆器在64V恒压激励下可产生高度约为9mm的火焰。联合测试结果表明,在安全状态下隔断机构能够较好地隔绝火焰的传递;在解保状态下起爆器产生的火焰可以顺利地通过隔断机构。该微起爆装置拥有较高集成化程度的起爆序列,能够实现大批量生产,对我国火工品研究具有一定的探索性意义。
Abstract:Aiming at the problem of the pyrotechnics miniaturization in modern ammunition, a micro-detonated device built-in MEMS safety and arming device was proposed, and fabricated by MEMS technology. The safety and arming device is driven by an electric actuator, and the detonator is a nickel-chromium alloy detonating bridge with an Al/CuO energetic composite film. It has been tested that the safety and arming device can achieve a large displacement under the driving of 11V voltage, the displacement distance is 1mm. The detonator can generate a 9mm height flame under 64V constant voltage excitation. After the joint test, the safety and arming device can block the flame in the safe condition, and the flame can pass through the safety and arming device in the arming condition. The micro-detonated device has a high integration of the explosive train, which can realize mass production and has an exploratory significance for the pyrotechnic research.
