Mach number

The Mach number (M or Ma), often only Mach (; German: [max]), is a dimensionless quantity in fluid dynamics representing the ratio of flow velocity past a boundary to the local speed of sound. It is named after Austrian physicist and philosopher Ernst Mach. M = u c , {\displaystyle \mathrm {M} ={\frac {u}{c}},} where: M is the local Mach number, u is the local flow velocity with respect to the boundaries (either internal, such as an object immersed in the flow, or external, like a channel), and c is the speed of sound in the medium, which in air varies with the square root of the thermodynamic temperature. By definition, at Mach 1, the local flow velocity u is equal to the speed of sound. 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). The local speed of sound, and hence the Mach number, depends on the temperature of the surrounding gas. The Mach number is primarily used to determine the approximation with which a flow can be treated as an incompressible flow. The medium can be a gas or a liquid. The boundary can be travelling in the medium, or it can be stationary while the medium flows along it, or they can both be moving, with different velocities: what matters is their relative velocity with respect to each other. The boundary can be the boundary of an object immersed in the medium, or of a channel such as a nozzle, diffuser or wind tunnel channelling the medium. As the Mach number is defined as the ratio of two speeds, it is a dimensionless quantity. If M < 0.2–0.3 and the flow is quasi-steady and isothermal, compressibility effects will be small and simplified incompressible flow equations can be used.

• Boom Overture - Wikipedia

  Boom Overture is a supersonic airliner under development by Boom Technology. The aircraft is designed to cruise at a maximum speed of Mach 1.7 or 975 knots "Knot (unit)") (1,806 km/h; 1,122 mph), and is expected to reach supersonic speeds without causing a sonic boom at ground level by taking advantage of a physics phenomenon known as mach cutoff. It is expected to carry 60 to 80 passengers, depending on configuration, with a range of 4,250 nautical miles [nmi] (7,870 km; 4,890 mi). Boom aims to introduce the Overture in 2029. The company projects a market for over 1,000 supersonic aircraft serving more than 600 viable routes, with fares comparable to business class. Featuring a delta wing design similar to that of the Concorde, the Overture is expected to use composite materials in its [...] Boom targets a slower Mach 1.7 cruise speed. In January 2022, Boom announced a grant of US$60 million from the US Air Force’s AFWERX program to further develop the Boom Overture supersonic airliner. In July 2022, Boom announced a partnership with Northrop Grumman to develop a 'special mission' variant for the U.S. Government and its allies. Overture's introduction is now planned for 2027, while its first flight is now planned for 2028 with type certification expected in 2029. On July 19, 2022, Boom unveiled a significantly revised proposal for the production version of the Overture at the Farnborough Airshow. This version has four engines and a tailed delta wing. [...] ## Market [edit] According to the company, over 600 daily routes could be viable. At Mach 1.7 over water, transatlantic flight times would be reduced significantly: Newark to London in 3 hours 40 minutes, and Newark to Frankfurt in 4 hours 15 minutes. Boom estimates a potential market for 1,000 supersonic airliners by 2035. The Overture Superfactory has the capacity to assemble 33 aircraft per year on the first assembly line, and up to 66 per year with the addition of a second assembly line, supporting a market of 1,000 to 2,000 aircraft over a 10-year period.[citation needed]
