Lift-to-drag ratio — In aerodynamics, the lift to drag ratio, or L/D ratio ( ell over dee in the US, ell dee in the UK), is the amount of lift generated by a wing or vehicle, divided by the drag it creates by moving through the air. A higher or more favorable L/D… … Wikipedia
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
Drag (physics) — Shape and flow Form drag Skin friction 0% 100% 10% 90% … 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
Drag coefficient — In fluid dynamics, the drag coefficient (commonly denoted as: cd, cx or cw) is a dimensionless quantity that is used to quantify the drag or resistance of an object in a fluid environment such as air or water. It is used in the drag equation,… … Wikipedia
Aircraft — An aircraft is a vehicle which is able to fly through the Earth s atmosphere or through any other atmosphere. Rocket vehicles are not aircraft if they are not supported by the surrounding air. All the human activity which surrounds aircraft is… … Wikipedia
Aircraft flight control systems — consist of flight control surfaces, the respective cockpit controls, connecting linkages, and the necessary operating mechanisms to control an aircraft s direction in flight. Aircraft engine controls are also considered as flight controls as they … Wikipedia
Aircraft dynamic modes — Source: Flight dynamicsThe dynamic stability of a vehicle denotes the complete study of the motion occurring after the vehicle has been disturbed. If the aircraft returns to equilibrium without overshoot, the motion is a simple subsidence. If the … Wikipedia
Dihedral (aircraft) — For other uses, see Dihedral. The upward tilt of the wings and tailplane of an aircraft, as seen on this Boeing 737, is called dihedral angle Dihedral angle is the upward angle from horizontal of the wings or tailplane of a fixed wing aircraft.… … Wikipedia
trim drag — An increment in drag, resulting from the aerodynamic trimming of an aircraft. The tailplane in any aircraft produces lift, which may be positive or negative. In the process of producing lift, drag is also produced. If additional lift is required… … Aviation dictionary
Fictional military aircraft — are imagined aircraft which are used in fiction, in its various media, but do not exist in the real world. These aircraft may be conjectured variants of real world aircraft or they may be completely fabricated by the author. Contents 1 Fictional… … Wikipedia
