针对某型民用飞机试飞阶段的可达性评估方法开展研究。根据飞机结构特点对可达性的要求,对飞机各个部分提出不同的评估标准,分别进行可达性定性和定量两个方面的评估,建立了基于开敞率的可达性定量评估模型,为后续民机试飞阶段可达性评估提供方法参考和理论依据。 Research on the reachability evaluation method of flight test stage of a civil aircraft. According to the reachability requirements of aircraft structural characteristics, different evaluation criteria are put forward for each part of the aircraft, respectively qualitative and quantitative reachability assessment, and a reachability quantitative assessment model based on the open rate is established Subsequent civil aircraft flight test phase reachability assessment provides a reference and theoretical basis.
