可靠性设计在民用飞机环控系统中的应用

民用飞机环控系统可靠性设计的目标是保证飞机达到规定的可靠性定量指标和定性要求,以提高飞机的可靠度,降低运营费用,使飞机具有良好的经济性和市场竞争能力。民用飞机环控系统在设计中大量采用了冗余设计、成熟技术及标准化设计等设计手段,以保证飞机的可靠性和安全性。通过可靠性分析验证飞机平均故障间隔时间和签派可靠度是否满足环控系统设计要求。

Application of Reliability Design in Civil Aircraft Environment Control System

The purpose of the reliability design on civil aircraft environment control system is to ensure the aircraft meet the qualitative and quantitative reliability requirements, reduce the cost in working, and to make better economical and compete ability. In order to ensure the reliability and safety, a fairly large number of technology are used in aircraft environment control system design, redundancy design, mature technology and standardization design. Reliability analysis is used to validate whether mean time between failures and dispatch reliability meet the requirement.
