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 ...
Transonic flow occurs when there is mixed sub- and supersonic local flow in the same flowfield (typically with freestream Mach numbers from M = 0.6 or 0.7 to 1.2). Usually the supersonic region of the flow is terminated by a shock wave, allowing the flow to slow down to subsonic speeds. This complicates both computations and wind tunnel testing.
Transonic Flow - an overview | ScienceDirect Topics
Transonic flow refers to steady flows that occur when there is a transition between subsonic and supersonic flow. It is characterized by a surface called the transitional or sonic surface. AI generated definition based on: Fluid Mechanics (Second Edition), 1987
From Subsonic to Hypersonic Flow - Spartan College of …
2023年11月29日 · Transonic Flow. 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 Flow - an overview | ScienceDirect Topics
Transonic flows occur over aircraft flying near Mach 1, in the tip region of propeller blades, and in nozzles, turbines and compressors of jet engines. Transonic flows can be loosely defined as flows in which the local flow speed is close to the speed of sound.
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 .
Notable examples of the power of this method include the achievement of the Wright brothers in leaving the ground (after first building a wind tunnel), and more recently Whitcomb’s discovery of the area rule for transonic flow, followed by his development of aftloaded supercritical airfoils and winglets [2, 3, 4]. The process was expensive.
Transonic Flow - SpringerLink
2021年1月5日 · Under this condition the flow is called ‘transonic’. In this chapter we are going to study a special case of an external flow for which the free stream speed of the flow is close to the speed of sound, i.e. the Mach number is about unity.
Transonic Aerodynamics | Progress in Astronautics and Aeronautics
As the name implies, transonic aerodynamics is concerned with the flow phenomena that exist where the velocities are in the neighborhood of the local speed of sound. Since it is in this regime that civil aircraft cruise and military aircraft maneuver, flight at transonic speeds is a common occurrence for many aircraft.
