Nahüberschallflug
Nahüberschallflug refers to flight at speeds approaching the speed of sound. This range is typically considered to be between Mach 0.8 and Mach 1.0. During nahüberschallflug, the airflow over the aircraft's surfaces can experience both subsonic and supersonic velocities simultaneously, leading to complex aerodynamic phenomena.
As an aircraft accelerates towards the speed of sound, the air immediately surrounding its surfaces must accelerate
The development of swept wings in the mid-20th century was a direct response to the challenges posed
