Fundamentals of Flap Technologies in Modern Aircraft
Flaps are e high- flt devices mounted on thee trailing edge of ain aircraft 's wing. Their primary intencje is to increase the wing' s camber and, in many designs, its surface area. By doing so, they generate consignificationty more flt slower speeds morems, where they can be retracted or set to a slight deftion to optimes the 'to- drag ratio (L / D).
