摘要
横航向稳定性是影响飞翼布局飞机飞行品质的主要因素。通过添加展向三个翼段的上反角,拓展了传统无尾飞翼布局横航向稳定性设计的空间,并基于一套横航向稳定性参数高效求解工具,实现了稳定性分析的自动求解流程。通过在整个设计空间中的稳定性参数求解,参考有人驾驶飞机飞行品质规范MIL-F-8785C,获得了符合二级飞行品质的设计点,证明了无尾飞翼布局飞机在大范围的设计空间中存在着满足横航向稳定性品质的设计方案。
Dihedral angle of three panels is added to the conventional tailless flying wing aerodynamic configuration in this study,and the design space of Lateral-directional dynamic stability is extended in this paper.Combined with efficient softare,the stability is automatically analyzed.The results of the self-compiled program are closer to the wind tunnel experimental data.As the main aerodynamic estimation tool,it can not only satisfy the faster calculation speed,but also ensure better calculation accuracy.
