飞机单机寿命监控中瞬时油量的确定方法研究

摘要

实施单机寿命监控能够有效体现飞机寿命的差异性。针对飞参数据中瞬时油量数据缺失的问题，提出了采用平均油耗率和相似原理来估算飞机瞬时油量的方法，进而对飞机的损伤情况进行计算。通过对具体飞机大量飞参数据的处理及结果分析，讨论了油量确定方法的影响因素和适用范围，为相关飞机实施单机寿命监控提供了技术基础。%　　Implementation of single aircraft life monitoring can reflect the difference of aircraft life. To solve the problem of lacking instantaneous fuel volume data among flight data, a method to estimate aircraft instantaneous fuel volume was put forward, which employed average fuel consumption rate and similarity principle, and then aircraft damage was figured out. The influencing factors and the application scope of the fuel volume determination method were discussed through processing large quantity of flight data of concrete aircrafts and analyzing the results. The purpose was to provide supporting technology for monitoring individual aircraft fatigue life of relevant aircrafts.
