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
Wave drag — is an aerodynamics term that refers to a sudden and very powerful form of drag that appears on aircraft and blade tips moving at high subsonic and supersonic speeds. Overview Wave drag is caused by the formation of shock waves around the aircraft … Wikipedia
Supersonic transport — The Concorde supersonic transport had an ogival delta wing, a slender fuselage and four underslung Rolls Royce/Snecma Olympus 593 engines. A supersonic transport (SST) is a civilian supersonic aircraft designed to transport passengers at speeds… … Wikipedia
Aerodynamics — is a branch of dynamics concerned with studying the motion of air, particularly when it interacts with a moving object. Aerodynamics is closely related to fluid dynamics and gas dynamics, with much theory shared between them. Aerodynamics is… … Wikipedia
