The Mach number (M or Ma), often only ... So the regime of flight from Mcrit up to Mach 1.3 is called the transonic range. Supersonic: 1.2–5.0 794–3,308 915 ...
In aerodynamics, the critical Mach number (Mcr or M*) ... Dassault Mirage III, and MiG 21, are intended to exceed Mach 1.0 in level flight, and are therefore designed ...
A Machmeter is an aircraft pitot-static system flight instrument that shows the ratio of the true airspeed to the speed of sound, a dimensionless quantity called Mach number. This is shown on a Machmeter as a decimal fraction. An aircraft flying at the speed of sound is flying at a Mach number of one, expressed as Mach 1.
What is supersonic flight? The Mach number is defined as a plane’s speed divided by the speed that sound waves move through the air. ... with Mach numbers greater than 1. The Mach number is an ...
The precise Mach number at which a craft can be said to be flying at hypersonic speed ... So the regime of flight from Mcrit up to Mach 1.3 is called the transonic ...
Transonic (or transsonic) flow is air flowing around an object at a speed that generates regions of both subsonic and supersonic airflow around that object. [1] The exact range of speeds depends on the object's critical Mach number, but transonic flow is seen at flight speeds close to the speed of sound (343 m/s at sea level), typically between Mach 0.8 and 1.2.
Graph of altitude/speed region envelope for Lockheed U-2 depicting coffin corner. Coffin corner (also known as the aerodynamic ceiling [1] or Q corner) is the region of flight where a fast but subsonic fixed-wing aircraft's stall speed is near the critical Mach number, making it very difficult to keep an airplane in stable flight.
During flight, a wing produces lift by accelerating the airflow over the upper surface. This accelerated air can, and does, reach supersonic speeds, even though the airplane itself may be flying at a subsonic airspeed ( Mach number < 1.0).
