航空气动力手册翼-身组合体编写小组在编写有关翼-身组合体纵向气动特性的过程中,小组收集了国内外使用的工程估算方法,对这些方法进行了分析和校核,以决定取舍,对某些部分进行了修改和补充。本文综合介绍对各种工程估算方法的分析、校核、修改及补充的情况,并通过29个算例将估算结果和实验进行了比较,以说明文献[12]所提供的估算方法的精确度和适用范围。至于文中所用到的一些近似处理和经验假设的理论依据,将在文献[16]中介绍。
Aerodynamic Manual Wing-Body Compositing Team In preparing the longitudinal aerodynamic characteristics of the wing-body assembly, the team collected engineering estimates used both at home and abroad, analyzed and reviewed these methods to determine the trade-offs , Some parts have been revised and supplemented. In this paper, we introduce the analysis, checking, modification and supplementing of various engineering estimation methods, and compare the estimation results with the experiments through 29 examples to illustrate the accuracy of the estimation method provided in [12] And the scope of application. The theoretical basis of some approximate treatments and empirical assumptions used in this paper will be introduced in [16].
