最小设计服役目标是确定用于疲劳分析的典型飞行任务剖面的最重要的参数之一。以研究确定大中型民用飞机最小设计服役目标的方法为目的,对国内民航统计数据进行分析,定位所设计飞机的预期市场,并获得主要分析参数,经过计算、分析进而确定最小设计服役目标。通过算例给出确定最小设计服役目标的方法,并简要介绍此方法的优点,供设计基于国内市场的民用飞机参考。
The minimum design service objective is to determine one of the most important parameters of a typical mission profile used for fatigue analysis. To study the method of determining the minimum design service target of medium and large civil aircraft, this paper analyzes the domestic civil aviation statistics, locates the expected market of the designed aircraft and obtains the main analysis parameters. After calculation and analysis, the minimum design service objective is determined. An example is given to determine the minimum design service objectives and a brief description of the advantages of this method for the design of civil aircraft based on the domestic market reference.
