Supersonic flight begins when an aircraft exceeds Mach 1, the speed of sound. At this point, airflow behavior changes dramatically due to the formation of shock waves.

Engineers must carefully design wing shapes, engine inlets, and fuselage profiles to reduce wave drag and maintain stability. Delta wings and swept-back wings are common solutions for high-speed aircraft.

Materials used in supersonic aircraft must withstand high aerodynamic heating. Specialized alloys and composites help manage thermal stresses.

Examples include military fighter jets and experimental commercial supersonic aircraft currently under development.

Future innovations aim to reduce sonic booms, making civilian supersonic travel more practical.
