1A device or coating for protection from excessive heat.
- ‘Andy Tyler has built a jet-powered shopping cart whose engine ‘glows red hot at temperatures up to 600°C, so he has to sit with his back to a heat shield.’’
- ‘If the salt solution is warmer, say near a car's muffler or heat shield, its conductivity will also increase.’
- ‘The front is based upon the current Russian, rather than Bulgarian, pattern and incorporates a steel heat shield.’
- ‘Its superior ability to block heat flow also means you can often eliminate the need for a heat shield.’
- ‘On the eastern side, a single elongated stone juts out at an angle in front of the mouth of the hearth, forming a heat shield.’
- ‘A transparent safety guard and heat shield protect the working area.’
- ‘A front spoiler, side skirts, radiator grille and sports exhaust with a specially-designed heat shield give the car an elegant look.’

- ‘Fire burst out on the ropes, burning them off, but not harming her since she had the heat shield up.’
- ‘The engine glows red hot at temperatures up to 600°C, so the driver needs a heat shield.’
- ‘Emhart identified problem areas where Chrysler might incur warranty and quality related issues, including the attachment of the heat shield to the vehicle's underbody.’
- ‘A slightly loose heat shield is unlikely to fall off completely and is not a terminal problem for the car, so if you don't want to pay BMW prices the first answer is to live with it.’

- ‘He has made a spectacle frame with solar batteries with two bulbs covered with heat shields at the bottom of the frame.’
- 1.1 An outer covering on a spacecraft, especially on the nose cone and leading edges, to protect it from the heat generated during re-entry into the earth's atmosphere.
- ‘Mission engineers are curious to learn how the heat shield behaved as it passed through the Martian atmosphere.’
- ‘The service module, and the orbital module are burned in the Earth's atmosphere, whilst the re-entry module uses its heat shield to make a safe return.’
- ‘But the prospect of checking out the heat shield and better understanding what happened to it when it came through the atmosphere is something that no other mission has ever done.’
- ‘We know all three parachutes did deploy and the heat shield worked.’
- ‘The gold heat shield on the orbital workshop was a replacement for an earlier shield that malfunctioned.’

- ‘This also minimizes the heat soak the vehicle is exposed to and eliminates the weight and expense of a heat shield.’
- ‘The engineers will be working for the next few months to analyze the performance of the heat shield that protected the spacecraft as it slammed into Mars' atmosphere.’
- ‘Because the shuttle was designed for repeated re-entry, an ablative heat shield was not an option.’
- ‘Once the velocity is slow enough and temperatures are safe, the heat shield at the bottom of the spacecraft will be jettisoned and the scientific instruments it was protecting can begin to take data.’
- ‘After the craft parachutes to dry land (with a splashdown as a backup option), NASA can easily recover it, replace the heat shield and launch it again.’
- ‘This caused gases to go through the damaged area during re-entry and thereby causing heat shield tiles to rip off.’
- ‘‘We went [to the area] to study the heat shield of course and we actually spent a couple of days studying the heat shield before we even realized there was a rock there,’ Squyres elaborated.’
- ‘The heat shield material, therefore, is state of the art.’
