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 structure must be strong enough to withstand heat and high speed air streams as well as dust and debris carried by the turbulent air. [ 1 ]
A muzzle shroud, linear compensator, blast shield, forward blast diverter or concussion reduction device (CRD) is a sleeve (either circular or otherwise) that attaches to and extends beyond the muzzle of a firearm in order to redirect some of the noise and concussion, or shock wave, from the muzzle blast forward and away from the shooter, and ...
A fragment also punctured the centerline external fuel tank of A-4 #310, positioned just aft of the jet blast deflector of catapult number 3. The resulting fire was fanned by 32- knot (59 km/h; 37 mph) winds and the exhaust of at least three jets.
A TA-4J Skyhawk aircraft waits behind the blast deflector for its turn at the catapult as another Skyhawk clears the flight deck of the auxiliary aircraft landing training ship USS LEXINGTON (AVT-16) during pilot carrier training.

The part that provides reverse thrust for thrust reversal is the deflector doors ("bucket") with aerodynamic contour on both inner and outer surface at the tailpipe of a jet engine. The doors are in a deployed location when thrust reversal takes effect and at stowed location when otherwise.

Blown flaps, blown wing or jet flaps are powered aerodynamic high-lift devices used on the wings of certain aircraft to improve their low-speed flight characteristics. They use air blown through nozzles to shape the airflow over the rear edge of the wing, directing the flow downward to increase the lift coefficient .
Jet engines can suffer major damage from even small objects being sucked into the engine. In the United States, the Federal Aviation Administration (FAA) requires that all engine types pass a test which includes firing a fresh chicken (dead, but not frozen) into a running jet engine from a small cannon. The engine does not have to remain ...
