Fixed wing aircraft

For fixed wing aircraft is the impetus - for the forward movement of the aircraft - through the air flow in the wings. It is formed on the wing by the predatory impulse of the wing a spinal approach over the wing caused a negative pressure and thus a top-facing buoyancy force. The wings must not be rigid, then some wings (variable angle), the flight speed to be adjusted such as the Tornado combat aircraft. In a broader sense to use the principle fixed wing aircraft with a fully flexible wings, as sliding and motor umbrellas, and with zerlegbaren wings as Hängegleitern. Many round canopy parachutes, especially Bremsfallschirme and case brakes (Engl. retarder instance) are not lenkbar and are therefore not one of the planes is expected. Ground effect vehicles compress air under a wing and are nothing more than low-flying fixed wing aircraft
