critical mach number वाक्य

At speeds above the critical Mach number, the airflow begins to become transonic, with local airflow in some places causing small sonic shock waves to form.
This results in a much weaker standing shock wave towards the rear of the upper wing surface and a corresponding " increase " in critical mach number.
Early transonic military aircraft, such as the Hawker Hunter and F-86 Sabre, were designed to fly satisfactorily even at speeds greater than their critical Mach number.
Wave drag is independent of viscous effects, and tends to present itself as a sudden and dramatic increase in drag as the vehicle increases speed to the Critical Mach number.
The problem is most severe at the wing root, so increasing the sweep here can further delay the onset and achieve a constant critical Mach number across the whole span.

As an aircraft enters the transonic region close to the speed of sound, airflow over specific parts can exceed the local critical Mach number and create supersonic shock waves, greatly increasing drag.
When the aircraft speed reaches its critical Mach number the accelerated airflow locally reaches the speed of sound and creates a small shock wave, even though the aircraft is still travelling below the speed of sound.
To prevent Mach stall from progressing, the pilot should keep the airspeed below the type's critical Mach number by reducing throttle, extending speed brakes, and if possible, extending the landing gear.
The Me 163 B-1a did not have any wingtip " washout " built into it, and as a result, it had a much higher critical Mach number than the Me 163 B-1.
Also the new wing was apparently aerodynamically inferior to the original Spitfire elliptic one, with lower critical Mach number, leading to someone quipping that " they rather should have left the Spitfire wing on the thing ".
