Mach number (M or Ma) (/mɑːk/; 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 the Austrian physicist and philosopher Ernst Mach. $${\displaystyle \mathrm {M} ={\frac {u}{c}},}$$ See more The Mach number is named after Moravian physicist and philosopher Ernst Mach, and is a designation proposed by aeronautical engineer Jakob Ackeret in 1929. As the Mach number is a dimensionless quantity rather than a unit of … See more While the terms subsonic and supersonic, in the purest sense, refer to speeds below and above the local speed of sound respectively, aerodynamicists often use the same terms to talk about particular ranges of Mach values. This occurs because of the … See more As a flow in a channel becomes supersonic, one significant change takes place. The conservation of mass flow rate leads one to expect that contracting the flow channel would increase the flow speed (i.e. making the channel narrower results in faster air … See more • Critical Mach number – lowest Mach number at which the airflow over some point of the aircraft reaches the speed of sound • Machmeter – Flight instrument • Ramjet – Atmospheric jet engine designed to operate at supersonic speeds See more Mach number is a measure of the compressibility characteristics of fluid flow: the fluid (air) behaves under the influence of compressibility in a similar manner at a given Mach … See more Flight can be roughly classified in six categories: For comparison: the required speed for low Earth orbit is approximately 7.5 km/s = Mach 25.4 in air at high altitudes.
