A typical blast fence at an airport An airman services a jet blast deflector (JBD) before flight operations aboard an aircraft carrier. A jet blast deflector (JBD) or blast fence is a safety device that redirects the high energy exhaust from a jet engine to prevent damage and injury.
The rounded shape (blunt body) of a capsule forms a shock wave that keeps most of the heat away from the heat shield, but a thermal protection system is still necessary. The space capsule must be strong enough to withstand reentry forces such as drag , and must reenter at a precise angle of attack to prevent a skip off the surface of the ...
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.

The thermal control subsystem can be composed of both passive and active items and works in two ways: Protects the equipment from overheating, either by thermal insulation from external heat fluxes (such as the Sun or the planetary infrared and albedo flux), or by proper heat removal from internal sources (such as the heat emitted by the internal electronic equipment).
Whipple shield used on NASA's Stardust probe. The Whipple shield or Whipple bumper, invented by Fred Whipple, [1] is a type of spaced armor shielding to protect crewed and uncrewed spacecraft from hypervelocity impact / collisions with micrometeoroids and orbital debris whose velocities generally range between 3 and 18 kilometres per second (1.9 and 11.2 mi/s).
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 ...
