ülehelikiirusega

ülehelikiirusega refers to exceeding the speed of sound. The speed of sound varies depending on the medium through which it is traveling, but in dry air at 20 degrees Celsius (68 degrees Fahrenheit), it is approximately 343 meters per second, or 1,235 kilometers per hour. Objects that travel at or above this speed are considered supersonic.

The phenomenon of an object breaking the sound barrier was first understood and achieved by test pilots. When an aircraft approaches and then exceeds the speed of sound, it creates a shock wave. This shock wave is responsible for the characteristic sonic boom heard on the ground. The sonic boom is essentially the sound of the sudden change in air pressure as the object passes through.

Supersonic flight has significant applications in aviation, particularly for military aircraft and some commercial airliners, though the latter are less common due to economic and environmental considerations. The design of supersonic aircraft differs from their subsonic counterparts, requiring specific aerodynamic features to manage the forces and pressures associated with high-speed flight. Research into supersonic and hypersonic (speeds five times the speed of sound or greater) travel continues to push the boundaries of aerospace engineering.
