  • normal 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. If a Mach wave is at right angles to the direction of movement of the body, the wave is called… …   Aviation dictionary

  • Shock 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 …   Wikipedia

  • shock 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,… …   Aviation dictionary

  • Normal shock tables — The Normal shock tables are a series of tabulated data listing the various properties before and after the occurrence of a normal shock wave.[1] With a given upstream Mach number, the post shock Mach number can be calculated along with the… …   Wikipedia

  • normal shock — A shock wave at 90° to the direction of airflow. It is found ahead of an airfoil approaching the speed of sound. Airflow behind the normal shock is invariably subsonic. Also called a normal shock wave …   Aviation dictionary

  • 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

  • Shock hardening — is a process used to strengthen metals and alloys, wherein a shock wave produces atomic scale defects in the material s crystalline structure. As in cold work, these defects interfere with the normal processes by which metallic materials yield… …   Wikipedia

  • Oblique shock — A small scale X 15 placed in a NASA supersonic wind tunnel produces an oblique shock wave at the nose of the model (along with other shocks). An oblique shock wave, unlike a normal shock, is inclined with respect to the incident upstream flow… …   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

  • Moving shock — In fluid dynamics, a moving shock is a shock wave that is traveling through a fluid (often gaseous) medium with a velocity relative to the velocity of the fluid already making up the medium.[1] As such, the normal shock relations require… …   Wikipedia
