Transonic - Wikipedia
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 ...
Since the advent of the jet engine, virtually all commercial transports now cruise in the transonic speed range. As the Mach number increases, shock waves appear in the flowfield, getting stronger as the speed increases.
Transonic Aircraft - NASA
2021年5月13日 · For aircraft speeds which are very near the speed of sound, the aircraft is said to be transonic. Typical speeds for transonic aircraft are greater than 250 mph but less than 760 mph, and the Mach number M is nearly equal to one, M ~= 1 . While the aircraft itself may be traveling less than the speed of sound, the air going around the aircraft ...
From Subsonic to Hypersonic Flow - Spartan College of …
2023年11月29日 · Subsonic aircraft designs feature thicker wings and more curvature, optimizing lift at lower speeds. The transonic flow occurs approximately between Mach 0.75 and Mach 1.20. This is a complex and critical speed range where the airflow around the aircraft transitions from subsonic to supersonic speeds.
Transonic Flight - SKYbrary Aviation Safety
In aeronautics, transonic refers to the condition of flight in which a range of velocities of airflow exist surrounding and flowing past an air vehicle or an airfoil that are concurrently below, at, and above the speed of sound in the range of Mach 0.8 to 1.2.
Transonic Flow: Structure & Dynamics | Vaia
Transonic flow refers to the condition where air flows around an object at speeds near the speed of sound, typically within the range of Mach 0.8 to 1.2. This aerodynamic phenomenon is crucial in the design and performance of aircraft as it involves complex changes in air pressure and density, leading to challenges such as shock waves and ...
Transonic Flow - centennialofflight.net
Transonic flow presents a special problem area as neither equations describing subsonic flow nor those describing supersonic flow may be accurately applied to the regime. At subsonic speeds, drag was composed of three main components—skin-friction drag, pressure drag, and induced drag (or drag due to lift).
It is generally recognized that the transonic speed range is that in which the flow about an aerodynamic configuration is an interacting mixture of sub-sonic and supersonic fields. The Mach number for the onset of such conditions is called the critical Mach number, thus transonic flow at subsonic freestream Mach numbers is called supercritical ...

Transonic - SKYbrary Aviation Safety
Transonic refers to the condition of flight in which a range of airflow velocities exist. The air surrounding and flowing past an aircraft or an airfoil which is in transonic flight will be concurrently below, at, and above the speed of sound.
