There are many factors which influence the amount of aerodynamic drag which a body generates. Drag depends on the shape, size, and inclination, of the object, and on flow conditions of the air passing the object. For a three dimensional wing, there is an additional component of drag, called induced drag, which will … Se mer For a lifting wing, the air pressure on the top of the wing is lower than the pressure below the wing. Near the tips of the wing, the air is free to move … Se mer The derivation of the equation for the induced drag is fairly tedious and relies on some theoretical ideas which are beyond the scope of the … Se mer For many years, wing designers have attempted to reduce the induced drag component by special shaping of the wing tips. The Wright Brothers used curved trailing edges on their rectangular wings based on wind tunnel … Se mer Lifting line theory shows that the optimum (lowest) induced drag occurs for an elliptic distribution of lift from tip to tip. The efficiency factor eis … Se mer NettetPreliminary Research Aerodynamic Design to Lower Drag, or Prandtl-D was an unmanned experimental glider-aircraft developed by NASA.
