考虑日历寿命的飞机梯次使用研究

Research in Echelon Usage of Aircraft Considering the Calendar Life

为了解决日历寿命对飞机梯次使用计划的影响问题,本文简述了当前飞机梯次使用方法——梯次使用图法,分析其主要缺点是没有对日历寿命指标进行控制,并从确定送修飞机、梯形图绘制、计划飞行时数分配等方面进行了改进。最后以余寿梯值方差为检验标准,运用实例证明了改进方法的优越性。

To resolve the influence of the calendar life to the echelon usage plan of aircraft, this paper have a brief description of the main echelon usage method （echelon usage plot）, and analysis that unconstraint of calendar life is the main disadvantage. And upswing the echelon usage plot by ensuring the overhaul aircrafts, drawing the echelon usage plot, and counting the planning fly-hour. At last, verify the availability of the method with an example by the standard of variance of lifespan step.
