wing drag
31wing flap — noun : a hinged or pivoted and sometimes extensible portion of an airplane wing used to increase the lift and drag for making landings at reduced speeds …
32effective profile drag — The difference between the total wing drag and the induced drag of a wing with the same aspect ratio but elliptically loaded. Profile drag is the combined effect of form drag and skin friction and which increases as square of the speed and is… …
33profile drag — noun aeronautics : the portion of the wing drag that is due to friction and turbulence in the fluid and that would be absent if it were nonviscous * * * profile drag, Aeronautics. the part of the drag of an airfoil resulting from its shape and… …
34induced drag — noun : the portion of the wing drag induced by or resulting from the generation of the lift …
35interference drag — Drag caused by flow interference at the wing/fuselage, wing/nacelle, and other such junctions. This interference leads to the modification of boundary layers and creates a greater pressure difference between the fore and aft areas on the surfaces …
36Lift-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… …
37Swept wing — A swept wing is a wing planform common on high speed aircraft, with the wing swept back instead of being set at right angles to the fuselage. This is a useful drag reducing measure for aircraft flying just below the speed of sound. Forward sweep… …
38Aspect ratio (wing) — In aerodynamics, the aspect ratio of a wing is defined as the square of the wing span divided by the wing area.:AR = {b^2 over S}where: b is the wing span, and: S is the wing area.Informally, a high aspect ratio indicates long, narrow wings,… …
39Flying wing — For the Canadian football position, see Flying wing (football). Flying wing Graphic rendering A flying wing is a tailless fixed wing aircraft which has no definite fuselage, with most of the crew, payload and equipment being housed inside the… …
40Oblique wing — on a NASA AD 1 An oblique wing (also called a slew wing) is a variable geometry wing concept. On an aircraft so equipped, the wing is designed to rotate on center pivot, so that one tip is swept forward while the opposite tip is swept aft. By… …
