  2. Mach number - Wikipedia

    en.wikipedia.org/wiki/Mach_number

    The transonic speed range is that range of speeds within which the airflow over different parts of an aircraft is between subsonic and supersonic. So the regime of flight from Mcrit up to Mach 1.3 is called the transonic range. Supersonic: 1.2–5.0 794–3,308 915–3,806 1,470–6,126 410–1,702

  3. Transonic - Wikipedia

    en.wikipedia.org/wiki/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.

  4. High-speed flight - Wikipedia

    en.wikipedia.org/wiki/High-speed_flight

    In these transonic speed ranges, compressibility causes a change in the density of the air around an airplane. 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

  5. Hypersonic speed - Wikipedia

    en.wikipedia.org/wiki/Hypersonic_speed

    The transonic speed range is that range of speeds within which the airflow over different parts of an aircraft is between subsonic and supersonic. So the regime of flight from Mcrit up to Mach 1.3 is called the transonic range. [citation needed] Northrop X-4 Bantam (Mach 0.9) — Supersonic [1.2–5) 921–3,836 mph (1,482–6,173 km/h; 412 ...

  6. Critical Mach number - Wikipedia

    en.wikipedia.org/wiki/Critical_Mach_number

    Supersonic aircraft, such as Concorde, Tu-144, the English Electric Lightning, Lockheed F-104, Dassault Mirage III, and MiG 21, are intended to exceed Mach 1.0 in level flight, and are therefore designed with very thin wings. Their critical Mach numbers are higher than those of subsonic and transonic aircraft, but are still less than Mach 1.0.

  7. Supersonic speed - Wikipedia

    en.wikipedia.org/wiki/Supersonic_speed

    The aerodynamics of supersonic aircraft is simpler than subsonic aerodynamics because the airsheets at different points along the plane often cannot affect each other. Supersonic jets and rocket vehicles require several times greater thrust to push through the extra aerodynamic drag experienced within the transonic region (around Mach 0.85–1.2).

    Its inaugural flight — 60 years ago in September 1964 — kicked off a golden era for supersonic aircraft. The plane would later achieve a speed of just over 2,000 miles per hour, nearly 50% ...

  9. Subsonic aircraft - Wikipedia

    en.wikipedia.org/wiki/Subsonic_aircraft

    A subsonic aircraft is an aircraft with a maximum speed less than the speed of sound (Mach 1). The term technically describes an aircraft that flies below its critical Mach number, typically around Mach 0.8. All current civil aircraft, including airliners, helicopters, future passenger drones, personal air vehicles and airships, as well as many ...
