Jet Blast Deflector
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. Without a deflector, jet blast can be dangerous to people, equipment, vehicles and other aircraft.Morrison, Rowena. ''ASRS Directline'', Issue Number 6, August 1993"Ground Jet Blast Hazard."Retrieved on November 13, 2009. Jet blast deflectors range in complexity from stationary concrete, metal or fiberglass fences to heavy panels that are raised and lowered by hydraulic arms and actively cooled. Blast deflectors can be used as protection from helicopter and fixed-wing aircraft propwash. At airports and jet engine service centers, jet blast deflectors can be combined with Soundproofing, sound-deadening walls to form a ground run-up enclosure within which a jet aircraft engine can safely and more qui ...

Aircraft Carrier
An aircraft carrier is a warship that serves as a seagoing airbase, equipped with a full-length flight deck and hangar facilities for supporting, arming, deploying and recovering carrier-based aircraft, shipborne aircraft. Typically it is the capital ship of a naval fleet, fleet (known as a carrier battle group), as it allows a naval force to power projection, project seaborne naval aviation, air power far from homeland without depending on local airfields for staging area, staging aerial warfare, aircraft operations. Since their inception in the early 20th century, aircraft carriers have evolved from wooden vessels used to deploy individual tethered reconnaissance balloons, to nuclear marine propulsion, nuclear-powered supercarriers that carry dozens of fighter aircraft, fighters, strike aircraft, military helicopters, airborne early warning and control, AEW&Cs and other types of aircraft such as unmanned combat aerial vehicle, UCAVs. While heavier fixed-wing aircraft such as a ...

Air Moorea Flight 1121
Air Moorea Flight 1121 was a de Havilland Canada DHC-6 Twin Otter which crashed into the ocean shortly after takeoff from Moorea Airport on Moorea Island in French Polynesia on 9 August 2007 killing all 20 people on board. It was bound for Tahiti's Faaʻa International Airport on a regular 7-minute service, one of the shortest on earth, scheduled a day. The crash resulted from loss of control due to failure of the airplane's elevator cable. Frequent takeoff and landing are believed to have been a major factor in the crash, because of wear and tear on the elevator cables, inspected only at fixed time intervals, regardless of usage. Another factor may have been jet-blast from large planes pushing back from the ramp at Fa'a'ā International. Background The aircraft, registration F-OIQI, serial number 608, was a de Havilland Canada DHC-6-300 Twin Otter powered by two Pratt & Whitney Canada PT6A-27. As of 8 August 2007, the airframe had flown 55,044 cycles in approximately 30, ...

Airbus A340
The Airbus A340 is a long-haul, long-range, wide-body passenger airliner that was developed and produced by Airbus. In the mid-1970s, Airbus conceived several derivatives of the Airbus A300, A300, its first airliner, and developed the A340 quadjet in parallel with the Airbus A330, A330 twinjet. In June 1987, Airbus launched both designs with their first orders and the A340-300 took its maiden flight on 25 October 1991. It was certified along with the A340-200 on 22 December 1992 and both versions entered service in March 1993 with launch customers Lufthansa and Air France. The larger A340-500/600 were launched on 8 December 1997; the A340-600 flew for the first time on 23 April 2001 and entered service on 1 August 2002. Keeping the eight-abreast economy cross-section of the A300, the early A340-200/300 has a similar airframe to the A330-200/300. Differences include four CFM56s instead of two high-thrust turbofans to bypass ETOPS restrictions on trans-oceanic routes, and a th ...

Muzzle Brake
A muzzle brake or recoil compensator is a device connected to, or a feature integral (ported barrel) to the construction of, the muzzle or barrel of a firearm or cannon that is intended to redirect a portion of propellant gases to counter recoil and unwanted muzzle rise. Barrels with an integral muzzle brake are often said to be ported. The concept of a muzzle brake was first introduced for artillery. It was a common feature on many anti-tank guns, especially those mounted on tanks, in order to reduce the area needed to take up the strokes of recoil and kickback. They have been used in various forms for rifles and pistols to help control recoil and the rising of the barrel that normally occurs after firing. They are used on pistols for practical pistol competitions, and are usually called compensators in this context.STI article

Space Shuttle Thermal Protection System
The Space Shuttle thermal protection system (TPS) is the barrier that protected the Space Shuttle Orbiter during the extreme heat of atmospheric reentry. A secondary goal was to protect from the heat and cold of space while in orbit. Materials The TPS covered essentially the entire orbiter surface, and consisted of seven different materials in varying locations based on amount of required heat protection: * Reinforced carbon–carbon (RCC), used in the nose cap, the chin area between the nose cap and nose landing gear doors, the arrowhead aft of the nose landing gear door, and the wing leading edges. Used where reentry temperature exceeded . * High-temperature reusable surface insulation (HRSI) tiles, used on the orbiter underside. Made of coated LI-900 silica ceramics. Used where reentry temperature was below 1,260 °C. * Fibrous refractory composite insulation (FRCI) tiles, used to provide improved strength, durability, resistance to coating cracking and weight reduc ...

Fourth-generation Jet Fighter
The fourth-generation fighter is a Jet fighter generations, class of jet fighters in service from around 1980 to the present, and represents design concepts of the 1970s. Fourth-generation designs are heavily influenced by lessons learned from the previous generation of combat aircraft. Jet fighter generations#Third generation, Third-generation fighters were often designed primarily as Interceptor aircraft, interceptors, being built around speed and Air-to-air missile, air-to-air missiles. While exceptionally fast in a straight line, many third-generation fighters severely lacked in maneuverability, as doctrine held that traditional Dogfight, dogfighting would be impossible at supersonic speeds. In practice, air-to-air missiles of the time, despite being responsible for the vast majority of air-to-air victories, were relatively unreliable, and combat would quickly become subsonic and close-range. This would leave third-generation fighters vulnerable and ill-equipped, renewing an i ...

Flight Deck
The flight deck of an aircraft carrier is the surface on which its aircraft take off and land, essentially a miniature airfield at sea. On smaller naval ships which do not have aviation as a primary mission, the landing area for helicopters and other VTOL aircraft is also referred to as the flight deck. The official U.S. Navy term for these vessels is "air-capable ships". Flight decks have been in use upon ships since 1910, the American pilot Eugene Ely being the first individual to take off from a warship. Initially consisting of wooden ramps built over the forecastle of capital ships, a number of battlecruisers, including the British and , the American and , and the Japanese ''Akagi'' and battleship ''Kaga'', were converted to aircraft carriers during the interwar period. The first aircraft carrier to feature a full-length flight deck, akin to the configuration of the modern vessels, was the converted liner which entered service in 1918. The armoured flight deck was ...
