Fleet Commonality
In aviation, fleet commonality is the economic and logistic benefits of operating a standardized fleet of aircraft that share common parts, training requirements, or other characteristics. Different types of commonality Commonality policies may be defined in a variety of ways, depending on the operator: * for civilian aircraft: ** By model, same generation (e.g. Boeing "Next Generation" 737-700, 737-800, and 737-900) ** By model, different generations (e.g. Boeing's "Next Generation" 737-700 and 737 MAX-7) ** By family (e.g. Boeing 737) ** Between families (e.g. deck, between Boeing 767-400ER, 777 and 737 NG) ** By manufacturer (e.g. Boeing) ** By engine (e.g. Rolls-Royce RB211) ** Any combination of the above * for military aircraft, the same can be said: ** By model, same generation ** By model, different generations (e.g. General Dynamics F-16A/B, multirole F-16C/D) ** By family (e.g. General Dynamics F-16) *Commonality can also be seen in engines : ** By famil ...

F-16
The General Dynamics F-16 Fighting Falcon is an American single-engine supersonic multirole fighter aircraft originally developed by General Dynamics for the United States Air Force (USAF). Designed as an air superiority day fighter, it evolved into a successful all-weather multirole aircraft with over 4,600 built since 1976. Although no longer purchased by the U.S. Air Force, improved versions are being built for export. In 1993, General Dynamics sold its aircraft manufacturing business to the Lockheed Corporation, which became part of Lockheed Martin after a 1995 merger with Martin Marietta. The F-16's key features include a frameless bubble canopy for enhanced cockpit visibility, a side-mounted control stick to ease control while maneuvering, an ejection seat reclined 30 degrees from vertical to reduce the effect of g-forces on the pilot, and the first use of a relaxed static stability/fly-by-wire flight control system that helps to make it an agile aircraft.

Avionics
Avionics (a portmanteau of ''aviation'' and ''electronics'') are the Electronics, electronic systems used on aircraft. Avionic systems include communications, Air navigation, navigation, the display and management of multiple systems, and the hundreds of systems that are fitted to aircraft to perform individual functions. These can be as simple as a searchlight for a police helicopter or as complicated as the tactical system for an airborne early warning platform. History The term "avionics" was coined in 1949 by Philip J. Klass, senior editor at ''Aviation Week & Space Technology'' magazine as a portmanteau of "aviation electronics". Radio communication was first used in aircraft just prior to World War I. The first Airborne radio relay, airborne radios were in zeppelins, but the military sparked development of light radio sets that could be carried by heavier-than-air craft, so that aerial reconnaissance biplanes could report their observations immediately in case they we ...

Fuselage
The fuselage (; from the French language, French ''fuselé'' "spindle-shaped") is an aircraft's main body section. It holds Aircrew, crew, passengers, or cargo. In single-engine aircraft, it will usually contain an Aircraft engine, engine as well, although in some amphibious aircraft the single engine is mounted on a hardpoint, pylon attached to the fuselage, which in turn is used as a floating Hull (watercraft), hull. The fuselage also serves to position the Flight control surfaces, control and Stabilizer (aeronautics), stabilization surfaces in specific relationships to Wing, lifting surfaces, which is required for aircraft stability and maneuverability. Types of structures Truss structure This type of structure is still in use in many lightweight aircraft using welding, welded steel tube trusses. A box truss fuselage structure can also be built out of wood—often covered with plywood. Simple box structures may be rounded by the addition of supported lightweight strin ...

Pratt & Whitney F100
The Pratt & Whitney F100 (company designation JTF22) is a low bypass afterburner, afterburning turbofan engine. It was designed and manufactured by Pratt & Whitney to power the U.S. Air Force's "FX" initiative in 1965, which became the McDonnell Douglas F-15 Eagle, F-15 Eagle. The engine was to be developed in tandem with the Pratt & Whitney F401, F401 which shares a similar core but with an upscaled fan for the U.S. Navy's Grumman F-14 Tomcat, F-14 Tomcat. The F401 was later abandoned due to costs and reliability issues. The F100 also powered the General Dynamics F-16 Fighting Falcon, F-16 Fighting Falcon for the Air Force's Lightweight Fighter (LWF) program. Development In 1967, the United States Navy and United States Air Force issued a joint engine Request for Proposals (RFP) for the F-14 Tomcat and the FX, which became the parallel fighter design competition that led to the McDonnell Douglas F-15 Eagle, F-15 Eagle in 1970.

General Electric T700
The General Electric T700 and CT7 are a family of turboshaft and turboprop engines in the class. Design and development In 1967, General Electric began work on a new turboshaft engine demonstrator designated the "GE12" in response to US Army interest in a next-generation utility helicopter. The GE12 was designed and conceived by GE's Art Adamson and Art Adinolfi. In 1967, both GE and Pratt & Whitney were awarded contracts to work parallel with each other to design, fabricate, and test the technology. The Army effort led, in the 1970s, to development of the Sikorsky S-70 Black Hawk, powered by twin GE "T700" turboshafts, the production descendant of the GE12. The T700 was initially bench-tested in 1973, passed military qualification in 1976, and went into production in 1978. The initial "T700-GE-700" is an ungeared free-turbine turboshaft, with a five-stage axial / one-stage centrifugal mixed-flow compressor, featuring one-piece "blisk" axial stages, with the inlet guide vanes a ...

Multirole Combat Aircraft
A multirole combat aircraft (MRCA) is a combat aircraft intended to perform different roles in combat. These roles can include air to air combat, air support, aerial bombing, reconnaissance, electronic warfare, and suppression of air defenses. Definition A Multi-role fighter aircraft is a type of military jet that is designed to perform a variety of combat missions rather than being specialized for a single role. These aircraft combine the capabilities of air-to-air fighters and air-to-ground attack aircraft, offering versatility and efficiency on the battlefield. More roles can be added, such as aerial reconnaissance, forward air control, and electronic-warfare aircraft. Attack missions include the subtypes air interdiction, suppression of enemy air defense (SEAD), and close air support (CAS). Multirole vs air-superiority Multirole has also been applied to one aircraft with both major roles, a primary air-to-air combat role, and a secondary role like air-to- ...

Rolls-Royce RB211
The Rolls-Royce RB211 is a British family of high-bypass turbofan engines made by Rolls-Royce Holdings, Rolls-Royce. The engines are capable of generating of thrust. The RB211 engine was the first production turbofan#Three-spool, three-spool engine and turned Rolls-Royce from a significant player in the aero-engine industry into a global leader. Originally developed for the Lockheed L-1011 TriStar, it entered service in 1972 and was the exclusive engine to power the L-1011. Mismanagement of the initial development and consequent cost issues led to the effective nationalisation of Rolls-Royce Limited, to save the workforce and the engine businesses important to the UK and many other aerospace and aircraft operating companies. In the early 1970s, the engine was reckoned by the company to be capable of at least 50 years of continuous development. The RB.211 was renamed, in 1989, to become the basis of the Rolls-Royce Trent family of engines when the RB211-524L was renamed to the ...

Aviation
Aviation includes the activities surrounding mechanical flight and the aircraft industry. ''Aircraft'' include fixed-wing and rotary-wing types, morphable wings, wing-less lifting bodies, as well as lighter-than-air aircraft such as hot air balloons and airships. Aviation began in the 18th century with the development of the hot air balloon, an apparatus capable of atmospheric displacement through buoyancy. Clément Ader built the "Ader Éole" in France and made an uncontrolled, powered hop in 1890. This was the first powered aircraft, although it did not achieve controlled flight. Some of the most significant advancements in aviation technology came with the controlled gliding flying of Otto Lilienthal in 1896. A major leap followed with the construction of the '' Wright Flyer'', the first powered airplane by the Wright brothers in the early 1900s. Since that time, aviation has been technologically revolutionized by the introduction of the jet engine which enabl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
