Fotografati per la prima volta i boom sonici degli aerei

The shock waves of the sonic boom of two jets were immortalized by NASA. A result never achieved.

It is an image destined to remain in history that captured by a team of NASA scholars who, for the first time, have “resumed” a sonic boom produced by the shock wave of two jet in flight. The images, created thanks to a ten-year research led by J.T. Heineck, in Mountain View, show two T-38s from the U.S. Air Force Test Pilot School, as they fly during a series of tests carried out at the Armstrong Flight Research Center in Edwards, California. Through strioscopy, a technique that allows you to observe the turbulences in the air or in the fluids crossed by a solid, you can admire the ripples of the atmosphere produced by the jet that exceed the speed of sound.

It is the exact instant in which a roar is heard on the ground, known in the jargon of “sonic boom“, caused by the breaking of the so-called sound wall. The data will be used for the design of the X-59 QueSST, a jet capable of reaching supersonic speed, without producing, however, the sonic boom, but a much quieter roar. The development of aircraft capable of flying at high speeds, but without producing sonicis booms, is the goal of researchers who aim to reduce the inconvenience to the population and the current restrictions on this type of flights.
