本文介绍了一种用于战斗机机载成员逃逸系统点火装置的设计。本系统采用4路集成化金属化高功率光纤耦合输出激光器模块作为点火光源,光纤芯径105μm,光纤输出功率0-5W可调。设计了基于固体继电器的激光器驱动电路,采用嵌入式微处理器控制多路激光起爆器,可精确实现多个机位的泄压、抛放舱盖、座椅弹射等系列动作,采用双路冗余的方法提高点火可靠性,与传统导爆索方式相比具有控制时序精准、可靠性高、更易实现复杂逻辑等优点。
This article describes a design for the fighter aircraft onboard member escape system ignition device. The system uses 4-way integrated metallized high-power fiber-coupled output laser module as the ignition source, fiber core diameter 105μm, optical fiber output power 0-5W adjustable. The laser drive circuit based on solid state relays is designed. The embedded microprocessor controls the multi-channel laser detonator, which can accurately achieve a series of actions such as releasing the pressure at multiple positions, releasing the hatch cover and seat ejection, Improve the ignition reliability, compared with the traditional detonating cord method has the advantages of accurate timing control, high reliability, easier to implement complex logic.
