喷气公务机总体参数和性能统计分析

Statistical Analysis of Relationship between Gross Parameters and Performance Data of Business Airplane

按照飞机设计的基本原理 ,通过对现有喷气公务机总体参数和性能数据的统计分析 ,寻找它们之间可能存在的内在关系 ,得到了 1 0个经验公式 ,包括使用空重与起飞重量、燃油重量与起飞重量、着陆重量与起飞重量、机翼面积与起飞重量、机翼面积与使用空重、机身长度与使用空重、内部容积与使用空重以及推力、巡航速度、后掠角、展弦比等一些组合参数之间的数学关系。另外还得到了推重比、翼载荷等常用参数的取值范围。这些统计结果为公务机概念设计提供了一些有用的数据。

Based on the elementary concepts of aircraft design and aerodynamics, statistical analysis is made for the gross parameters and performance of business airplane. The potential relations among these parameters are found. 10 experiential expressions are obtained from 33 data of the business airplane. These expressions are as follows: empty weight and take off weight, fuel weight and take off weight, land weight and take off weight, wing area and empty weight, fuselage length and empty weight as well as some other compounded parameters. Additionally, the value limits of some parameters are analyzed. These expressions and data are proved to be useful for the conceptual design of business airplanes.
