双吊舱联翼布局太阳能飞机气动弹性建模研究

Study of Model Build of Double-Podded Joined-Wing Solar Powered Aircraft

太阳能飞机一般都是大展弦比形式,气动弹性问题非常突出。先对飞机进行受力分析,确定在建立结构模型时需要考虑的关键问题,然后通过静力学分析确定吊舱所在位置,之后根据飞机外形参数建立详细的机翼结构模型和气动模型,再将飞机的结构模型和气动模型连接起来。对整个模型进行的气弹算例计算结果表明,这种建模是合理的。

Solar powered aircraft are generally high aspect wing, the aircraft should study its aeroelastic. Through to the aircraft forcenanalysis, the key to build model will be established, then determine the position of the pod through the staic analysis, third determine the detailed wing structures and pneumatic mode according to the aircraft shape parameters, at last link this two mode and analysis.
