Variable Sweep Wings Paper Presentation & Seminar

A variable-sweep wing is a wing configuration that allows to alter planform for various flight conditions. A variable-sweep wing can be moved during flight-usually between a swept-back position and a straight position. This allows it to take advantage of the aerodynamics of a swept wing at high speeds while avoiding the drawbacks of such a design at lower speeds. It is successful in this respect, but the added mass and complexity required counter the benefits and stand in the way of widespread adoption. The term variable-geometry is often used synonymously with swing-wing, though strictly speaking swing-wing is a specific type of variable geometry.
