Fuel Fraction
In aerospace engineering, an aircraft's fuel fraction, fuel weight fraction, or a spacecraft's propellant fraction, is the weight of the fuel or propellant divided by the gross take-off weight of the craft (including propellant): :\ \zeta = \frac The fractional result of this mathematical division is often expressed as a percent. For aircraft with external drop tanks, the term internal fuel fraction is used to exclude the weight of external tanks and fuel. Fuel fraction is a key parameter in determining an aircraft's range, the Range (aircraft), distance it can fly without refueling. Louis Charles Breguet, Breguet’s aircraft range (aircraft), range equation describes the relationship of range with airspeed, lift-to-drag ratio, Thrust specific fuel consumption, specific fuel consumption, and the part of the total fuel fraction available for cruise, also known as the cruise fuel fraction, or cruise fuel weight fraction. In this context, the Breguet range is proportional to - ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
GlobalFlyer At KSC Before Launch
The Scaled Composites Model 311 Virgin Atlantic GlobalFlyer (Aircraft registration, registered N277SF) is an aircraft designed by Burt Rutan in which Steve Fossett first flew a solo nonstop airplane flight around the world in slightly more than 67 hours (2 days 19 hours) in 2005. The flight speed of set the world record for the fastest nonstop non-refueled circumnavigation, beating the mark set by the previous Rutan-designed Rutan Voyager, Voyager aircraft at 9 days 3 minutes with an average speed of . The aircraft was owned by the pilot Steve Fossett, sponsored by Richard Branson's Virgin Atlantic airline, and built by Burt Rutan's company, Scaled Composites. The two companies subsequently worked together on Virgin Galactic. In February 2006, Fossett flew the GlobalFlyer for the longest aircraft flight distance in history: . Design and construction The GlobalFlyer was specifically designed to make an uninterrupted (non-refueled) circumnavigation of the globe with a single ...

Panavia Tornado
The Panavia Tornado is a family of twin-engine, variable-sweep wing multi-role combat aircraft, jointly developed and manufactured by Italy, the United Kingdom and Germany. There are three primary #Variants, Tornado variants: the Tornado IDS (interdictor/attack aircraft, strike) fighter-bomber, the Tornado ECR (electronic warfare aircraft, electronic combat/reconnaissance aircraft, reconnaissance) SEAD aircraft and the Tornado ADV (air defence variant) interceptor aircraft. The Tornado was developed and built by Panavia Aircraft GmbH, a tri-national consortium consisting of British Aerospace (previously British Aircraft Corporation), Messerschmitt-Bölkow-Blohm, MBB of West Germany, and Aeritalia of Italy. It first flew on 14 August 1974 and was introduced into service in 1979–1980. Due to its multirole design, it was able to replace several different types of aircraft in the adopting air forces. The Royal Saudi Air Force (RSAF) became the only export operator of the Tornad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
CS100
The Airbus A220 is a family of five-abreast narrow-body airliners by Airbus Canada Limited Partnership (ACLP). It was originally developed by Bombardier Aviation and had two years in service as the Bombardier CSeries. The program was launched on 13 July 2008. The smaller A220-100 (formerly CS100) first flew on 16 September 2013, received an initial type certificate from Transport Canada on 18 December 2015, and entered service on 15 July 2016 with launch operator Swiss Global Air Lines. The longer A220-300 (formerly CS300) first flew on 27 February 2015, received an initial type certificate on 11 July 2016, and entered service with airBaltic on 14 December 2016. Both launch operators recorded better-than-expected fuel burn and dispatch reliability, as well as positive feedback from passengers and crew. In July 2018, the aircraft was rebranded as the A220 after Airbus acquired a majority stake in the programme through a joint venture that became ACLP in June 2019. The A220 t ...
