Lift-induced drag — In aerodynamics, lift induced drag, induced drag, vortex drag, or sometimes drag due to lift, is a drag force that occurs whenever a moving object redirects the airflow coming at it. This drag force occurs in airplanes due to wings or a lifting… … Wikipedia
Lift (force) — For other uses, see Lift. Boeing 747 8F landing A fluid flowing past the surface of a body exerts a surface force on it. Lift is the component of this force that is perpendicular to the … Wikipedia
Ground effect in aircraft — Aircraft may be affected by a number of ground effects, aerodynamic effects due to a flying body s proximity to the ground.One of the most important of these effects is the Wing In Ground effect, which refers to the reduction in drag experienced… … Wikipedia
Disk loading — The MV 22 Osprey tiltrotor has a relatively high disk loading, producing visible blade tip vortices from condensation of the marine air in this photo of a vertical takeoff … Wikipedia
Elliptical wing — An elliptical wing is a wing planform shape, first seen on aircraft in the 1930s, which minimizes induced drag. Elliptical taper shortens the chord near the wingtips in such a way that all parts of the wing experience equivalent downwash, and… … Wikipedia
Flight dynamics — is the science of air and space vehicle orientation and control in three dimensions. The three critical flight dynamics parameters are the angles of rotation in three dimensions about the vehicle s center of mass, known as pitch , roll and yaw… … Wikipedia
Vortex — A vortex (pl. vortices ) is a spinning, often turbulent, flow of fluid. Any spiral motion with closed streamlines is vortex flow. The motion of the fluid swirling rapidly around a center is called a vortex. The speed and rate of rotation of the… … Wikipedia
Horseshoe vortex — The horseshoe vortex model is a simplified representation of the vortex system of a wing. In this model the wing vorticity is modelled by a bound vortex of constant circulation, travelling with the wing, and two trailing vortices, therefore… … Wikipedia
ground effect — i. The change in the aerodynamic reaction on an aircraft caused by the proximity of the ground. An aircraft, helicopter, or any other flying machine flying very near to the ground experiences an increase in lift. This additional lift or… … Aviation dictionary
Pusher configuration — An aircraft constructed with a pusher configuration has the engine mounted forward of the propeller which faces in a rearwards direction giving an appearance that the aircraft is pushed through the air. Sometimes the propeller is situated at the… … Wikipedia
