Every aircraft has a drag divergence Mach number. For aircraft not designed for high subsonic flight, this can be as low as Mach 0.8." Captain Richard Levy told us that from inside the cockpit ...

In his book The Race for Mach 1, Kempel does the math: “At a Mach number of 0.929, at about 624 mph, [the XP-86] had overcome only about 18 percent of the airplane’s peak drag-rise.

Everyone has heard of a fast plane having its speed described in terms of its Mach number. Mach 2, for example, means twice the speed of sound in air, Mach 3 is three times, and so on.

For turbulent boundary layers in supersonic and hypersonic flow, there exist only three experiments which give turbulence data at a Mach number greater than 4 (Fernholz and Finley 1977, 1981): the hot ...

The XB-1 reached Mach 1.122 when it broke the sound barrier for the first time after about 12 minutes into the flight. ... Aircraft speed is measured by a Mach number, ...

Most jets fly a typical profile cruising at a specific Mach number, often around Mach .80. Flight management computers provide recommendations depending on the priority of fuel saving or speed.

1838: Ernst Mach is born in the small town of Chirlitz, then part of the Austrian Empire. The scientist would go on to conduct research in many fields, but his most memorable work in aerodynamics ...

Every aircraft has a drag divergence Mach number. For aircraft not designed for high subsonic flight, this can be as low as Mach 0.8." Captain Richard Levy told us that from inside the cockpit ...
