民用飞机构型差异管理分析

Analysis of Configuration Difference Management for Civil Aircraft

在民用飞机研制及后续的交付运营过程中,构型差异是无法规避的客观存在,这种构型差异包括单机构型状态与型号设计之间的差异、单机设计状态与设计要求之间的差异,以及制造状态与设计要求之间的差异。准确记录这些差异,评估差异的影响,提供有效证据,以明确差异的可接受程度,确定限制和相关对策,是飞机研制过程的关键问题和难点问题。以研制阶段的试验试飞机为例,对飞机设计构型差异和制造构型差异产生的过程进行分析,提出了对构型差异管理的改进建议。

In the course of the development of civil aircraft and the subsequent delivery and operation process,it is impossible to avoid the configuration differences existing objectively. The configuration differences include the difference between the single ship and type design,the difference between the single status and single design requirements,and the difference between the manufacture state and the design requirements. It is the key problem and difficulty in the aircraft development process to record the differences exactly,evaluate the effect of differences,and provide effective evidence in order to make clear the limit relevant countermeasure. Based on the fight test aircraft,this paper analyzed the configuration differences of design and the configuration differences of manufacture.Improvement suggestions for management of the configuration differences were proposed.
