进行了一项研究来评估通过数值优化进行计算机机翼设计的可行性。该设计程序将全潜力、无粘性空气动力学代码与共轭梯度优化算法相结合。选择了三个设计问题来演示设计技术。第一个涉及修改后掠翼内侧 50% 的上表面，以减少受到机翼体积限制的冲击阻力。第二个涉及修改同一后掠翼的整个上表面（除了尖端部分）以增加升阻比，但受到机翼体积和升力系数的限制。最后一个问题涉及修改低速机翼的内侧 50%，以实现良好的失速进展。三个案例的结果表明，该技术足够准确，可以显着改进设计目标。
A study was conducted to assess the feasibility of performing computerized wing design by numerical optimization. The design program combined a full-potential, inviscid aerodynamic code with a conjugate gradient optimization algorithm. Three design problems were selected to demonstrate the design technique. The first involved modifying the upper surface of the inboard 50% of a swept wing to reduce the shock drag subject to a constraint on wing volume. The second involved modifying the entire upper surface of the same swept wing (except the tip section) to increase the lift-drag ratio, subject to constraints on wing volume and lift coefficient. The final problem involved modifying the inboard 50% of a low-speed wing to achieve good stall progression. Results from the three cases indicate that the technique is sufficiently accurate to permit substantial improvement in the design objectives.
