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] Without a deflector, jet blast can be dangerous to ...
A blast pen and memorial at the former RAF Kenley A Hawker Hurricane in a revetment at RAF Wittering in 1940. A blast pen was a specially constructed E-shaped double bay at British Royal Air Force (RAF) Second World War fighter stations, being either 150 ft (46 m) or 190 ft (58 m) wide and 80 ft (24 m) front-to-back, accommodating aircraft for safe-keeping against bomb blasts and shrapnel ...
Jet blast is the phenomenon of rapid air movement produced by the jet engines of aircraft, particularly on or before takeoff. A large jet-engined 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] Jet blast can be a hazard to people or other unsecured ...
Wing fence. Close up of the wing fences of a Sukhoi Su-22. This plane was used by Former East German Air Force and retired after German unification. Wing fences, also known as boundary layer fences and potential fences are fixed aerodynamic devices attached to aircraft wings. Often seen on swept-wing aircraft, wing fences are flat plates fixed ...
December 20, 1968. Trinity was the code name of the first detonation of a nuclear weapon, conducted by the United States Army at 5:29 a.m. MWT [ a ] (11:29:21 GMT) on July 16, 1945, as part of the Manhattan Project. The test was of an implosion-design plutonium bomb, nicknamed the "gadget", of the same design as the Fat Man bomb later detonated ...
Maho Beach is a beach on the Dutch side of the Caribbean island of Saint Martin, in the territory of Sint Maarten.It is famous for being adjacent to the Princess Juliana International Airport and is a popular site for tourists and plane watchers, who visit the beach to watch aircraft on final approach land at the airport right at the edge of the water.
Bremer wall. A Bremer wall, or T-wall, is a twelve-foot-tall (3.66 m) portable, steel-reinforced concrete blast wall of the type used for blast protection throughout Iraq and Afghanistan. The Bremer barrier resembles the smaller 3-foot-tall (0.91 m) Jersey barrier, which has been used widely for vehicle traffic control on coalition military ...
Vortilon. Vortilons are fixed aerodynamic devices on aircraft wings used to improve handling at low speeds. [1] [2] The vortilon was invented [3] by aerodynamicists working at Douglas Aircraft who had previously developed the engine pylons for the Douglas DC-8. The original pylons which wrapped around the leading edge of the wing had to be cut ...
