[′thər·məl ′bar·ē·ər]

(aerospace engineering)

A limit to the speed of airplanes and rockets in the atmosphere imposed by heat from friction between the aircraft and the air, which weakens and eventually melts the surface of the aircraft. Also known as heat barrier.

thermal barrier

One of the limits to the speed at which an aircraft can fly. Exceeding the limiting speed can result in damage to the structure. A thermal barrier is normally related to aircraft flying at low levels at very high indicated air speeds.
