Tip Extensions, Winglets, and C-wings: Conceptual Design and Optimization

  title={Tip Extensions, Winglets, and C-wings: Conceptual Design and Optimization},
  author={S. Andrew Ning and I. M. Kroo},
Conceptual wing design analysis methods are combined with numerical optimization to find minimum drag wings subject to constraints on lift, weight, pitching moment, and stall speed. For conceptual design studies root bending moment is often used to assess wing weight. However, this is often a poor indication of wing weight, especially for nonplanar configurations. The weight model used not only retains simplicity, but also accounts for the depth of the wing structural box and variations in area… CONTINUE READING
