Transsonický is a term used to describe a range of speeds encountered by an object or aircraft as it transitions from subsonic to supersonic speeds. This transition occurs roughly between Mach 0.8 and Mach 1.2. During this flight regime, the airflow around the object can become a complex mixture of both subsonic and supersonic regions. As an object accelerates through this range, shock waves begin to form on its surface. These shock waves are areas of abrupt change in pressure, temperature, and density, and they can cause significant increases in drag and changes in aerodynamic forces. Designing aircraft to operate efficiently and stably in the transsonic regime presents considerable engineering challenges. The "sound barrier" is the point at which an object breaks through this transsonic range and achieves sustained supersonic flight. Understanding and mitigating the effects of transsonic flight is crucial for the design of high-speed aircraft, missiles, and other aerospace vehicles.
