先进战斗机生命保障系统

生命保障系统为适应新型战斗机发展需求，围绕"以人为保障对象"系统特征，采用基于系统工程的需求/功能分析方法，从飞机总体、生理、六性、飞管、任务等需求出发，提出系统需求，开展需求分析向工程实践转化研究，确定分解了系统、成品的设计及指标要求。通过系统架构优化、提高快速响应能力研究，建立大系统综合的系统架构。基于数据共享、控制融合的飞管平台以及氧气介质传感器技术，结合六性、FMECA和FTA，开展数字协同环境下生命保障系统综合设计，系统电子信息化程度取得突破，具备高度综合的全数字显示与控制、自主诊断和状态监测能力，获得高效维修保障能力，为实现玻璃化座舱、快速出动、快速布防、跨区域作战、自主保障提供有力支撑。

Life support system in advanced fighter

To adapt to the development of the new-type fighter aircraft, additional functions and requirements of the life support system are proposed based on the human-oriented design concept and demands of the general design, physiology, "Six Character", ergonomics, vehicle management, and missions. This paper reflects on the design experience of foreign advanced fighter aircraft and uses the requirement and function analysis method of system engineering. Through the research of transformation from requirement analysis to engineering practice, design requirements and indexes of the system with its airborne equipment are determined and broken down. The studies on optimizing system architecture and improving quick response capability establish the life support system framework integrated with the general aircraft system. Benefiting from the open vehicle management system with data sharing, fusion control, oxygen sensor technology, "Six Character", Failure Modes, Effects and Criticality Analysis (FMECA), and Fault Tree Analysis (FTA), integrated design of the life support system in digital coordination environment has been carried out and a breakthrough in the electronic information has been achieved so that the highly-integrated ability of all-digital display, self-diagnosis, and condition monitoring is available in the life support system. The proposed design improves its maintainability and provides strong support for the fighter aircraft in glass canopy, fast response, fast deployment, interregional operation, independent support, and high survivability.
