Drag divergence Mach number — The drag divergence Mach number (not to be confused with critical Mach number) is the Mach number at which the aerodynamic drag on an airfoil or airframe begins to increase rapidly as the Mach number continues to increase[1]. This increase can… … Wikipedia
drag divergence Mach number — The Mach number at which there is a sudden rise in wing drag as a result of the formation of shock waves. Buffet may take place and control difficulty may occur at this Mach number … Aviation dictionary
Swept 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… … Wikipedia
Airfoil — An airfoil (in American English) or aerofoil (in British English) is the shape of a wing or blade (of a propeller, rotor or turbine) or sail as seen in cross section. An airfoil shaped body moved through a fluid produces a force perpendicular to… … Wikipedia

Coffin corner (aviation) — The coffin corner (or Q corner) is the altitude at or near which a fast fixed wing aircraft s stall speed is equal to the critical Mach number, at a given gross weight and G force loading. At this altitude the airplane becomes nearly impossible… … Wikipedia
Critical Mach number — Transonic flow patterns on an aircraft wing showing the effects at critical mach. In aerodynamics, the critical Mach number (Mcr) of an aircraft is the lowest Mach number at which the airflow over any part of the aircraft reaches the speed of… … Wikipedia
D'Alembert's paradox — In fluid dynamics, d Alembert s paradox (or the hydrodynamic paradox) is a contradiction reached in 1752 by French mathematician Jean le Rond d Alembert.[1] D Alembert proved that – for incompressible and inviscid potential flow – the drag force… … Wikipedia
