In view of burning and explosion dangerous source which exist in explosive and its manufacture, the security quantitative analysis model of the emergency open system based on the burning and explosion dangerous source evaluation method is proposed, and the system security of the emergency open system is analyzed by the burning and explosion dangerous source evaluation method. The analysis results basically show the regulation of the emergency open system security. The model and the proposed research method can provide reference for security study of other aero explosive device system. The feasibility and reliability of burning and explosion dangerous source evaluation of the emergency open system have been heightened. The security quantitative analysis model of emergency open system in virtue of burning and explosion dangerous source evaluation method can be a good method of the choice of the security design of the whole system. Keywords: System security analysis, Burning and explosion dangerous source evaluation method, Emergency open system, EED IntroductionTo meet the aircraft flight test team members' needs for the air emergency evacuation, it is required that the probability of the false triggering of the emergency opening system of the aircraft's service door is not more than 0.001 under the premise of the confidence level can not being less than 90% when the aircraft is under normal conditions. Therefore, it is need for a security quantitative analysis of the emergency opening system. The so-called quantitative analysis of system security, that is to analyze and determine the security problems of the emergency opening system, the probability of its possible harmful effects, and calculate the security changes taken by the appropriate safety measures in the system. By comparing the compliance status of the emergency opening system's risk before and after the security reform measures being taken, the decision-making basis is provided for selecting the best design. The existing explosion hazard assessment has been focused on the production process effects on the security of EED (Electro-Explosive Devices), which is no need to consider in the practical application of EED. Therefore, the explosion hazard assessment method can not be fully applicable to the security analysis of the emergency opening system, new analytical methods are required to explore in the practice of specific research projects. Therefore, based on the explosion hazard assessment method, a security quantitative analysis model for the emergency opening system is put forward. Basic Structure of EEDEED like hot bridge wire squibs, initiators, and detonators are energetic devices which are activated by application of electric current. They are first elements in an ignition train producing high temperature flames and ignite energetic materials such as pyrotechnics and booster charges. They are composed of ignition pins, bridge wire element, primary charge, and main charge which are enclosed in a metal case. The schematic structure of a t...
