This would give the tip a ground speed of 3.6 km/s (Mach 10), which would be matched by a hypersonic airplane carrying the payload module, with transfer at an altitude of 100 km. The tether would be made of existing commercially available materials: mostly Spectra 2000 (a kind of ultra-high-molecular-weight polyethylene ), except for the outer ...
At Mach 0.65, u is 65% of the speed of sound (subsonic), and, at Mach 1.35, u is 35% faster than the speed of sound (supersonic). An F/A-18 Hornet creating a vapor cone at transonic speed just before reaching the speed of sound. The local speed of sound, and hence the Mach number, depends on the temperature of the surrounding gas.
In aerodynamics, 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 pressure, density, temperature, and stagnation pressure ratios.

Dimensionless numbers (or characteristic numbers) have an important role in analyzing the behavior of fluids and their flow as well as in other transport phenomena. [1] They include the Reynolds and the Mach numbers, which describe as ratios the relative magnitude of fluid and physical system characteristics, such as density, viscosity, speed of sound, and flow speed.
Project Mayhem, the Air Force's secret new hypersonic bomber, is underway. Development on the bomber, which travels at Mach 10, just took a big step forward.
Mach 10 or variation, may refer to: Mach number for ten times the speed of sound Hypersonic speed of 10 times the speed of sound; Mach 10 Training Systems, a coaching consultancy of James McCallum (cyclist) "Mach 10" (song), a 2007 song by Dub Pistols off the album Speakers and Tweeters; MachTen, a Unix-like operating system based on BSD and ...
Flow in this regime is still Mach number dependent. Simulations start to depend on the use of a constant-temperature wall, rather than the adiabatic wall typically used at lower speeds. The lower border of this region is around Mach 5, where ramjets become inefficient, and the upper border around Mach 10–12. [citation needed]
