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 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.
English: A U.S. Navy Douglas TA-4J Skyhawk of Training Wing 3 (TW-3) 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 in the Gulf of Mexico, 1 April 1989.
As an aircraft is taxied onto the catapult, the wings are spread and a large jet blast deflector panel rises out of the flight deck behind the engine exhaust. Prior to final catapult hookup, final checkers (inspectors) make final exterior checks of the aircraft, and loaded weapons are armed by ordnancemen .
The Air Department added several significant changes to the flight deck, including enlarging the jet blast deflectors (JBD) and installing more powerful catapults to handle the new Grumman F-14 Tomcat, which Kitty Hawk was due to receive for its next deployment.
Jet blast is the phenomenon of rapid air movement produced by the jet engines of aircraft, particularly on or before takeoff. A large jet-engine aircraft can produce winds of up to 100 knots (190 km/h; 120 mph) [ 1 ] as far away as 60 metres (200 ft) behind it at 40% maximum rated power. [ 2 ]
These types of FOD are very difficult to track and manage once they are introduced onto the airfield. A jet engine intake, engine blast, and propeller or helicopter rotor draft then can pick up the debris easily. This material, once loose around operational aircraft, can lead to serious safety concerns, including personnel injury and equipment ...
