adj. close to the speed of sound; moving at 700–780 mph (1127–1255 km/h) at sea level. [1940–45] transonicOf or pertaining to the speed of a body in a surrounding fluid when the relative speed of the fluid is subsonic in some places and supersonic in others. This is encountered when passing from subsonic to supersonic speed and vice versa.

Translationstransonic
transonic[tran′sän·ik] (physics) That which occurs or is occurring within the range of speed in which flow patterns change from subsonic to supersonic (or vice versa), about Mach 0.8 to 1.2, as in transonic flight or transonic flutter. transonicAn aircraft flight at speed ranges in which the airflow over some parts is subsonic and in other places supersonic. The transonic speed region lies between 0.8 and 1.2 Mach. This is the region in which an aircraft transitions from subsonic speeds to speeds equal to or higher than the speed of sound. In this speed range, abrupt changes in flight characteristics can take place. See subsonic.transonic
tran·son·ic (tran-son'ik), In ultrasound, describes a region of a relatively unattenuating medium. A distinction should be made between a transonic region and an acoustic echo. [trans- + sonic] transonic
