Featherlite Trailers is an all-aluminum trailer manufacturer, located in Cresco, Iowa. It is the oldest all-aluminum trailer brand in the United States, [ 1 ] [ 2 ] and today manufactures horse trailers and a range of specialty trailers.
The America class (formerly the LHA(R) class) is a ship class of landing helicopter assault (LHA) type amphibious assault ships for the United States Navy (USN). The class is designed to put ashore a Marine Expeditionary Unit using helicopters and MV-22B Osprey V/STOL transport aircraft, supported by AV-8B Harrier II or F-35 Lightning II V/STOL aircraft and various attack helicopters.
The United States Navy built nearly 1,200 tank landing ships, classified as "Landing Ship, Tank" or "LST", from the World War II-era up through the early 1970s. [47] The Newport class , which entered service in 1969, would be the last class built and the only class capable of exceeding 20 knots.
The automatic shut off nozzle shuts off when pressure in the fuel system reaches 9 psi (62 kPa) or greater. Due to the pressure introduced into the fuel tank, most tanks require additional structure to prevent bursting or damaged weld joints. This bursting is both a safety and environmental hazard.
A small amount of fuel in the tank leaves pumps on the floor of the tank exposed to the air-fuel mixture, and an electric pump is a potential ignition source. The explosion of a Thai Airways International Boeing 737 in 2001 and a Philippine Airlines 737 in 1990 also occurred in tanks that had a small amount of residual fuel.
While the accuracy of the official findings is still questioned in this case, similar explosions have occurred in other aircraft. It is possible to reduce the chance of fuel tank explosions by a fuel tank inerting system or fire fighting foam in the tanks. [5] The Boeing 737, for example, has two systems that reduce the chance of a fuel tank ...
A wet wing (also referred to as integral fuel tanks [1]) is an aerospace engineering technique where an aircraft's wing structure is sealed and used as a fuel tank.. The use of wet wings has become common among civilian designs, from large transport aircraft, such as airliners, to small general aviation aircraft.
Conformal fuel tanks are mounted above the wings to replace the drag of underwing tanks. Combined, they carry 1,590 kg (3,500 lb) of extra fuel, while adding extra lift and expanding combat radius by 130 nmi (240 km) with a small transonic acceleration penalty.
