mach shock wave
1Shock wave — Bombshock redirects here. For the Transformers character, see Micromasters#Bombshock. For other uses, see shockwave. Schlieren photograph of an attached shock on a sharp nosed supersonic body. A shock wave (also called shock front or simply shock …
2shock wave — An area or sheet of discontinuity (i.e., of abrupt changes in conditions) set up in a supersonic field of flow, through which the fluid undergoes a finite decrease in velocity accompanied by a marked increase in pressure, density, temperature,… …
3oblique shock wave — A shock wave that forms on a sharp pointed object moving through the air at a speed greater than the speed of sound. Air passing through an oblique shock wave is slowed down but if the wave angle is less than about 70°, it still will be… …
4Mach 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… …
5Wave 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 …
6mach number — mach. Also, Mach number. [1935 40] * * * ▪ physics in fluid mechanics, ratio of the velocity of a fluid to the velocity of sound in that fluid, named after Ernst Mach (Mach, Ernst) (1838–1916), an Austrian physicist and philosopher. In the… …
7Mach 1 — , MACH NUMBER When airplanes first started to fly, their speed was measured like that of a moving vehicle on the ground. As air speeds increased, that method became obsolete, and a new method had to be found. Ernst Mach (1838 1916), an… …
8Mach tuck — is an aerodynamic effect, whereby the nose of an aircraft tends to pitch downwards as the airflow around the wing reaches supersonic speeds. Note that the aircraft is subsonic, and traveling significantly below Mach 1.0, when it experiences this… …
9Mach 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… …
10Mach wave — In fluid dynamics, a Mach wave is a pressure wave traveling with the speed of sound caused by a slight change of pressure added to a compressible flow. These weak waves can combine in supersonic flow to become a shock wave if sufficient Mach… …
