In the Cosmic Era time line, the ablative armor concept is applied in similar capacity to the anti-beam coating and laminated armor technologies utilised by mobile suits as a form of protection against beam and laser weaponry. Selected spacecraft are also able to deploy ablative gel for high-velocity atmospheric reentries.
In engineering, a heat shield is a component designed to protect an object or a human operator from being burnt or overheated by dissipating, reflecting, and/or absorbing heat. [1] The term is most often used in reference to exhaust heat management and to systems for dissipating frictional heat. Heat shields are used most commonly in the ...
The first reentry test of a PICA-X heat shield was on the Dragon C1 mission on 8 December 2010. [35] The PICA-X heat shield was designed, developed and fully qualified by a small team of a dozen engineers and technicians in less than four years. [33] PICA-X is ten times less expensive to manufacture than the NASA PICA heat shield material. [36]
The golden areas are MLI blankets on the Mars Reconnaissance Orbiter. The principle behind MLI is radiation balance. To see why it works, start with a concrete example - imagine a square meter of a surface in outer space, held at a fixed temperature of 300 K (27 °C; 80 °F), with an emissivity of 1, facing away from the sun or other heat sources.
The sunshield component attaches to the main spacecraft, and its booms expand outward spreading out the heat shield and separating the layers. [24] During launch the shield is folded up; later, when it is in space, it is carefully unfurled. [24] When the sunshield is fully spread open, it is 14.6 meters (48 ft) wide by 21.1 meters (69 ft) long ...

US Postal Service employees work inside the Los Angeles Mail Processing & Distribution Center on December 3. The facility is currently processing 1 million packages per day.
Thermal engineering may be practiced by mechanical engineers and chemical engineers. One or more of the following disciplines may be involved in solving a particular thermal engineering problem: thermodynamics, fluid mechanics, heat transfer, or mass transfer. One branch of knowledge used frequently in thermal engineering is that of thermofluids.
