767-300
The Boeing 767 is an American wide-body aircraft developed and manufactured by Boeing Commercial Airplanes. The aircraft was launched as the 7X7 program on July 14, 1978, the prototype first flew on September 26, 1981, and it was certified on July 30, 1982. The original 767-200 entered service on September 8, 1982, with United Airlines, and the extended-range 767-200ER in 1984. It was stretched into the in October 1986, followed by the 767-300ER in 1988, the most popular variant. The 767-300F, a production freighter version, debuted in October 1995. It was stretched again into the 767-400ER from September 2000. To complement the larger 747, it has a seven-abreast cross-section, accommodating smaller LD2 ULD cargo containers. The 767 is Boeing's first wide-body twinjet, powered by General Electric CF6, Rolls-Royce RB211, or Pratt & Whitney JT9D turbofans. JT9D engines were eventually replaced by PW4000 engines.

Boeing KC-767
The Boeing KC-767 is a military aerial refueling and strategic transport aircraft developed from the Boeing 767-200ER. The tanker received the designation KC-767A, after being selected by the U.S. Air Force (USAF) initially to replace older KC-135Es. In December 2003, the contract was frozen and later canceled due to corruption allegations. The tanker was developed for the Italian and Japanese air forces, who ordered four tankers each. Financing of the development of the aircraft has largely been borne by Boeing, in the hope of receiving major orders from the USAF. Boeing's revised KC-767 proposal to the USAF was selected in February 2011 for the KC-X program under the designation KC-46. Development Commercial Derivative Air Refueling Aircraft At the start of the 2000s a considerable and sudden increase in their maintenance costs was leading the U.S. Air Force to run a procurement program for the replacement of around 100 of its oldest KC-135E Stratotankers. Most USAF K ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Boeing 777
The Boeing 777, commonly referred to as the Triple Seven, is an American long-range wide-body airliner developed and manufactured by Boeing Commercial Airplanes. It is the world's largest twinjet. The 777 was designed to bridge the gap between Boeing's other wide body airplanes, the twin-engined 767 and quad-engined 747, and to replace older DC-10s and L-1011 trijets. Developed in consultation with eight major airlines, with a first meeting in January 1990, the program was launched in October, with an order from United Airlines. The prototype was rolled out in April 1994, and first flew in June. The 777 entered service with the launch customer, United Airlines, in June 1995. Longer range variants were launched in 2000, and were first delivered in 2004.

Unit Load Device
A unit load device (ULD) is a container used to load luggage, freight, and mail on wide-body aircraft and specific narrow-body aircraft. It allows preloading of cargo, confidence the containerised load will fit in the aircraft and efficient planning of aircraft weight and balance and reduced labour and time in loading aircraft holds compared with 'bulk-loading' single items of cargo or luggage by hand. Each ULD has its own packing list or manifest so that its contents can be tracked. A loaded aircraft cargo pallet secured with a cargo net also forms a ULD, but its load must be gauged for size in addition to being weighed to ensure aircraft door and hold clearances. The IATA publishes ULD regulations and notes there are 900,000 in service worth more than US$1 billion, averaging $ each. Types ULDs come in two forms: pallets and containers. ULD pallets are rugged sheets of aluminium with rims designed to lock onto cargo net lugs. ULD containers, also known as cans and pods, a ...

Twinjet
A twinjet or twin-engine jet is a jet aircraft powered by two engines. A twinjet is able to fly well enough to land with a single working engine, making it safer than a single-engine aircraft in the event of failure of an engine. Fuel efficiency of a twinjet is better than that of aircraft with more engines. These considerations have led to the widespread use of aircraft of all types with twin engines, including airliners, fixed-wing military aircraft, and others. Aircraft configurations There are three common configurations of twinjet aircraft. The first, common on large aircraft such as airliners, has a podded engine usually mounted beneath, or occasionally above or within, each wing. The second has one engine mounted on each side of the rear fuselage, close to its empennage, used by many business jets. In the third configuration both engines are within the fuselage, side-by-side, used by most fighters since the 1960s. Later fighters using this configuration include the Su- ...

Supercritical Airfoil
A supercritical airfoil (supercritical aerofoil in British English) is an airfoil designed primarily to delay the onset of wave drag in the transonic speed range. Supercritical airfoils are characterized by their flattened upper surface, highly Camber (aerodynamics), cambered ("downward-curved") aft section, and larger leading-edge radius compared with NACA airfoil, NACA 6-series laminar airfoil shapes. Standard wing shapes are designed to create lower pressure over the top of the wing. Both the thickness distribution and the camber of the wing determine how much the air accelerates around the wing. As the speed of the aircraft approaches the speed of sound, the air accelerating around the wing reaches Mach number, Mach 1 and shockwaves begin to form. The formation of these shockwaves causes wave drag. Supercritical airfoils are designed to minimize this effect by flattening the upper surface of the wing. The origins of the supercritical airfoil can be traced back to the German a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
