使用CFD软件对某机场塔台幕墙在水平和高度方向上不同安装顺序与安装阶段的风场进行了模拟,对各测点的风场数据进行了分析。研究表明,塔台幕墙施工过程中的风场变化主要受到水平方向施工顺序的影响。在水平方向上,优先封闭主要迎风面幕墙能有效减小后续幕墙施工时的场风压;而在高度方向上,从上至下的安装顺序对后续幕墙风场干扰相对较小一些。

Chinese Journal of Aeronautics 2014年第4期27卷 781-790页

作者： Wu Zhao Wang Lixin lin jiaming Ai Junqiang School of Aeronautic Science and Engineering Beihang University

A new identification method is proposed to solve the problem of the influence on the loaded excitation signals brought by high feedback gain augmentation in lateral-directional aerodynamic parameters identification of fly-by-wire（FBW） passenger airliners. Taking for example an FBW passenger airliner model with directional relaxed-static-stability, through analysis of its signal energy distribution and airframe frequency response, a new method is proposed for signal type selection, signal parameters design, and the appropriate frequency relationship between the aileron and rudder excitation signals. A simulation validation is presented of the FBW passenger airliner＇s lateral-directional aerodynamic parameters identification. The validation result demonstrates that the designed signal can excite the lateral-directional motion mode of the FBW passenger airliner adequately and persistently. Meanwhile, the relative errors of aerodynamic parameters are less than 5%.
