transonic speed

Transonic speed refers to the range of velocities approximately between Mach 0.8 and Mach 1.2, where the airflow around an aircraft transitions from subsonic (below the speed of sound) to supersonic (above the speed of sound). In this range, some parts of the airflow are subsonic while others are supersonic, creating complex shock waves and aerodynamic effects that can impact stability and control. Achieving and navigating this speed zone requires specialized design considerations to manage these aerodynamic challenges effectively.
