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
Mach wave — A wave formed in front of a body when it is moving at the speed of sound. The waves do not move ahead of the body; they bunch up and form a Mach wave. A Mach wave is at right angles to the direction of movement of the body and is called a normal… … Aviation dictionary
Mach number — (mathrm{Ma} or M) (generally pronEng|ˈmɑːk, sometimes IPA|/ˈmɑːx/ or IPA|/ˈmæk/) is the speed of an object moving through air, or any fluid substance, divided by the speed of sound as it is in that substance. It is commonly used to represent an… … Wikipedia
Ramjet — A ramjet, sometimes referred to as a stovepipe jet, or an athodyd, is a form of jet engine that contains no major moving parts. Unlike most other airbreathing jet engines, ramjets have no rotary compressor at the inlet, instead, the forward… … Wikipedia
