shock waves/ shock wavesPan Am 103TWA 800Accident investigations such as of Pan Am 103 and TWA 800 reveal the key role of shock-wave propagation in destroying the aircraft when an on-board explosion occurs. This paper surveys shock wave propagation inside an aircraft fuselage, caused either by...
THE question of the minimum realizable sonic boom shock pressure rise is, in a sense, a closed one. For any given aircraft weight, flight Mach number and altitude, if the aircraft is sufficiently long, then shock waves may be avoided altogether. This is a consequence of two phenomena: the...
单词shock wave 释义shock wave moving region of very high air pressure caused by an explosion or an aircraft moving faster than sound 激震波, 冲击波, 激波(由爆炸或超音速飞机引起的) (fig 比喻) As soon as news of the tragedy was announced, shock waves spread rapidly to all parts of the cou...
In several ways shocks come into existence by artificial generation, such as with nuclear or chemical explosions, with the sonic boom of supersonic aircraft and any supersonic flying projectile, by a bullet pushing the air in the barrel of a rifle, as bow waves around an obstacle in a ...

4.10 Shock Waves Shock wave in fluids could be generated by the sudden, intense disturbance of a fluid. This disturbance could be, for example, powerful explosion, or flight of the supersonic aircraft. Supersonic aircraft produce shock waves that propagate through the atmosphere at a speed higher...

Very frequently, the shock wave/boundary layer interaction has also been found in ‘‘internal’’ flows. With most of the interaction flows appearing in a variety of flow devices including ducts, pipelines, supersonic wind tunnels, supersonic inlets of aircraft engines, supersonic ejectors, etc....
1.A large-amplitude compression wave, as that produced by an explosion or by supersonic motion of a body in a medium. 2.A severe disruption, disturbance, or reaction:The bad news sent shock waves through the stock market. American Heritage® Dictionary of the English Language, Fifth Edition...
Some of these tests can be made in wind tunnels, but the need for full flight conditions simulation, the problem of tunnel wall interference, and the short distance the shocks can be examined from the aircraft, limit the usefulness of wind tunnel tests. Previous measurement techniques for ...
