提出一种新的通用航空飞行器布局方案。应用基于二次曲线的模线设计方法,构造通用航空飞行器翼身组合体的布局方案。通过二次曲线的控制点和形状参数实现参数化外形建模,提高了布局方案设计的效率,为进一步的气动特性计算和布局方案设计优化奠定了基础。采用修正的牛顿流理论和一阶平面面元法,对通用航空飞行器进行高超声速气动特性计算,并对其飞行轨迹进行了仿真和优化。计算结果验证了通用航空飞行器布局方案的合理性,显示了参数化外形建模方法在通用航空飞行器布局选择和进一步深入研究中的实用性。
Proposed a new general aviation aircraft layout program. The design method of mold line based on quadratic curve is used to construct the layout scheme of the wing assembly of general aviation vehicle. Parametric shape modeling is achieved through the control points and shape parameters of the quadratic curve so as to improve the efficiency of the layout scheme design and lay a foundation for further aerodynamic characteristics calculation and layout design optimization. Based on the modified Newtonian theory and the first-order plane-plane method, the hypersonic aerodynamic characteristics of GA are calculated, and their flight paths are simulated and optimized. The calculation results verify the rationality of GA aircraft layout scheme and show the practicability of parametric profile modeling in GA aircraft layout selection and further study.
