transsonický

Transsonic refers to the range of speeds between subsonic and supersonic, typically defined as speeds slightly above the speed of sound. In the context of aerodynamics and fluid dynamics, the speed of sound is the speed at which sound waves propagate through a medium, such as air. At transsonic speeds, the airflow around an object, such as an aircraft, can transition from subsonic to supersonic and vice versa, leading to complex aerodynamic phenomena.

The term is particularly relevant in the design and operation of aircraft, as it represents a critical range where the airflow over the aircraft's surfaces can become turbulent and unpredictable. This can result in phenomena such as shock waves, which are abrupt changes in pressure and density, and boundary layer separation, where the airflow detaches from the surface of the aircraft. These effects can significantly impact the aircraft's performance, stability, and control.

Transsonic speeds are also of interest in the study of supersonic and hypersonic flows, as they provide a transition region where the fundamental principles of fluid dynamics can be studied and understood. In engineering applications, transsonic speeds are often encountered in the design of high-speed aircraft, such as supersonic jets and hypersonic vehicles, as well as in the development of high-speed trains and other high-speed transportation systems.
