| Blown flap | Blown flaps are a powered aerodynamic high-lift device the wings of certain aircraft to improve the low-speed lift during takeoff and landing. The process is sometimes called a boundary layer control system (BLCS). They were a popular design feature in the 1960s, but fell from use due to their complex maintenance needs. Today a simpler version can be found on military transport aircraft, although the term is not widely used. (references) | ||
