The X-15, at Mach 6.72, is one of the fastest manned aircraft. Cooled nickel-titanium skin; highly integrated (due to domination of interference effects: non-linear behaviour means that superposition of results for separate components is invalid), small wings, such as those on the Mach 5 X-51A Waverider. High-hypersonic 10.0–25.0 6,615–16,537
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.
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 ...

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.
The Alfvén Mach number (also known as the Alfvén number, Alfvénic Mach number, and magnetic Mach number; M A or M M) is a dimensionless quantity representing the ratio of the relative velocity of a fluid to the local Alfvén speed. It is used in plasma physics, where it is analogous to the Mach number but based on Alfvén waves rather than ...
The following is a list of speed records for various types of vehicles.This list only presents the single greatest speed achieved in each broad record category; for more information on records under variations of test conditions, see the specific article for each record category.
Compressible flow (or gas dynamics) is the branch of fluid mechanics that deals with flows having significant changes in fluid density.While all flows are compressible, flows are usually treated as being incompressible when the Mach number (the ratio of the speed of the flow to the speed of sound) is smaller than 0.3 (since the density change due to velocity is about 5% in that case).
