RMSG-3下民用直升机L/HIRF分析

Analysis of Civil Helicopter L/HIRF under RMSG-3

从工程应用的角度出发,采用基本理论研究的研究方法,深入研究了RMSG-3标准在民用直升机的L/HIRF分析的应用。分析了L/HIRF防护退化模式,建立了L/HIRF敏感度评估体系,确定了重要维修项目确定原则,采用矩阵法制定了维修间隔期,确定了维修任务判断方法。为今后民用直升机L/HIRF分析工作及预防性维修任务的确定提供帮助。

From the perspective of engineering application,the application of RMSG-3 standard in L/HIRF analysis of civil helicopter is studied in depth by using the research method of basic theory.This paper analyzes the L/HIRF protection degradation mode,establishes the L/HIRF sensitivity evaluation system,determines the determination principle of important maintenance items,determines the maintenance interval by matrix method,and determines the maintenance task judgment method.It can provide help for the analysis of L/HIRF and the determination of preventive maintenance task of civil helicopter in the future.
