thermal barrier

[′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

An element of low heat conductivity placed on an assembly to reduce or prevent the flow of heat between highly conductive materials; used in metal window or curtain wall designs in cold climates.

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.
