== Purpose ==

The main purpose of the circulation control wing is to increase the [[lifting force]] of an aircraft at times when large lifting forces at low speeds are required, such as [[takeoff]] and [[landing]]. Wing [[Flap (aircraft)|flaps]] and [[Leading edge slats|slats]] are currently used during landing on almost all aircraft and on takeoff by larger jets. While flaps and slats are effective in increasing lift, they do so at a high cost of drag.<ref name="cc" /> The benefit of the circulation control wing is that no extra drag is created and the lift coefficient is greatly increased. It is being claimed that such a system could increase the landingmaximum coefficient of lift in the landing configuration of a [[Boeing 737]] by 150% to 250%, thus reducing approach speeds by 35% to 45% and landing distances by 55% to 75% and that; such advances in wing design could allow for a dramatic wingreduction in the size reductionof inthe large,wing wideof bodya jetslarge jet airplane.<ref name="cc" />
