为设计某大型支线客机总体方案,在自行设计支线客机总体参数数据库的基础上,应用统计方法对支线客机总体参数和涡扇发动机总体参数进行分析,获得了一些有用的统计关系式,包括使用空重和最大起飞重量、后掠角与展弦比、进近速度与着陆场长等飞机总体参数之间的统计关系式和起飞推力与发动机风扇直径、起飞推力与发动机净重、起飞推力与短舱长度等涡扇发动机参数之间的统计关系式。这些统计结果为大型客机方案设计提供了一定的参考。
In order to design a general scheme of a large regional airliner, based on the design of the overall parameter database of regional airliner, the statistical method is used to analyze the overall parameters of the regional airliner aircraft and the overall parameters of the turbofan engine. Some useful statistical relationships are obtained, including the use of empty Weight and maximum takeoff weight, sweep angle and aspect ratio, approach speed and landing length of the aircraft and other parameters of the overall statistical relationship between takeoff thrust and the diameter of the engine fan, takeoff thrust and net weight of the engine, takeoff thrust and nacelle Length and other turbofan engine parameters between the statistical relationship. These statistics provide a reference for the design of large passenger aircraft.
