thermal barrier
thermal barrier n (Aeronautics) an obstacle to flight at very high speeds as a result of the heating effect of air friction. Also called: heat barrier Thesaurus| Noun | 1. | thermal barrier - a limit to high speed flight imposed by aerodynamic heatingheat barrierlimit, bound, boundary - the greatest possible degree of something; "what he did was beyond the bounds of acceptable behavior"; "to the limit of his ability" |
thermal barrier
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. (building construction) thermal break Thermal barrierAn 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 break, thermal barrierAn element of low heat conductivity placed in an assembly to reduce or prevent the flow of heat between highly conductive materials; used in some metal window or curtain wall designs intended for installation in cold climates.thermal barrierOne 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.thermal barrier
