In this paper, the application of laser pyrotechnic device with dual seat single and dual state control function in airborne ejection escape system is studied. The system can meet the requirement of pilot's escape in emergency condition with two seats on board. The laser pyrotechnic device described in this paper takes the manual firing pyrotechnic laser as the ignition energy for the cabin life saving device, uses the optical fiber device to transmit the laser energy, designs the state selection switch for single and dual state control, and uses the laser explosive with different functions to realize the safety and life saving of the pilots in the left and right cabin. The device has the characteristics of novel structure, small volume, light weight, strong anti-electromagnetic interference, high safety and reliability, and is an ideal pyrotechnic device for the airborne ejection escape system in the future.
In this paper, in order to study the high temperature resistance of the transmission path of laser pyrotechnic system, the design of the high temperature resistant laser pyrotechnic system of the transmission path is designed. Combining with the design and research of the high temperature resistant multi-mode laser collimator, the high temperature resistant light energy transmission path is developed, and the laser energy transmission path through environmental test is used to carry out the system. The experimental results show that the high temperature resistant optical energy transmission path can make the laser pyrotechnic device fire normally after the high temperature test at 400℃ for 30 minutes and the mechanical environment test, which proves that the design of the high temperature resistant optical energy transmission path is feasible.
According to the demand of laser initiating device miniaturization and low power consumption of weapon system, research on the low power pulse laser detonation circuit with super capacitor. Established a dynamic model of laser output based on super capacitance storage capacity, discharge voltage and programmable output pulse width. The output performance of the super capacitor under different energy storage capacity and discharge voltage is obtained by simulation. The experimental test system was set up, and the laser diode of low power pulsed laser detonation circuit was tested and the laser output waveform of laser diode in different energy storage capacity and discharge voltage was collected. Experiments show that low power pulse laser detonation based on super capacitor energy storage circuit discharge with high efficiency, good transient performance, for a low power consumption requirement, for laser detonation system and low power consumption and provide reference light miniaturization of engineering practice.
