NACA Airfoil
The NACA airfoils are airfoil shapes for aircraft wings developed by the National Advisory Committee for Aeronautics (NACA). The shape of the NACA airfoils is described using a series of digits following the word "NACA". The parameters in the numerical code can be entered into equations to precisely generate the cross-section of the airfoil and calculate its properties. Origins NACA initially developed the numbered airfoil system which was further refined by the United States Air Force at Langley Research Center. According to the NASA website: Four-digit series The NACA four-digit wing sections define the profile by: # First digit describing maximum camber as percentage of the chord. # Second digit describing the distance of maximum camber from the airfoil leading edge in tenths of the chord. # Last two digits describing maximum thickness of the airfoil as percent of the chord. For example, the NACA 2412 airfoil has a maximum camber of 2% located 40% (0.4 chords) from the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pratt & Whitney Canada PW306A
The Pratt & Whitney Canada PW300 series is a family of turbofan jet engines developed by Pratt & Whitney Canada specifically for business jet applications. Design and development The PW 300 series has been developed in partnership with MTU who are responsible for the low pressure turbine. The first variant, the PW305A, has the following configuration and was designed with a core flexible enough for engines with take-off thrusts from 4,500 to 7,000 lb : a single-stage fan driven by a three-stage low pressure turbine, supercharging a four-stage axial/single-stage centrifugal high-pressure compressor, driven by a two-stage high-pressure turbine. An annular combustor is used. There is no forced mixing before the bypass and core streams leave the engine through a common nozzle. The engine is controlled with a dual channel Full Authority Digital Engine Control (FADEC) system. The PW307A is a new centre-line engine developed specifically for a tri-jet application on the Dassault Fal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turbofan
The turbofan or fanjet is a type of airbreathing jet engine that is widely used in aircraft engine, aircraft propulsion. The word "turbofan" is a portmanteau of "turbine" and "fan": the ''turbo'' portion refers to a gas turbine engine which achieves mechanical energy from combustion, and the ''fan'', a ducted fan that uses the mechanical energy from the gas turbine to force air rearwards. Thus, whereas all the air taken in by a turbojet passes through the combustion chamber and turbines, in a turbofan some of that air bypasses these components. A turbofan thus can be thought of as a turbojet being used to drive a ducted fan, with both of these contributing to the thrust. The ratio of the mass-flow of air bypassing the engine core to the mass-flow of air passing through the core is referred to as the bypass ratio. The engine produces thrust through a combination of these two portions working together; engines that use more Propelling nozzle, jet thrust relative to fan thrust are ...

IAI Galaxy
The Gulfstream G200, formerly known as the IAI Galaxy, is a twin-engine business jet. It was designed originally by Israel Aerospace Industries (IAI) and was produced by IAI for Gulfstream Aerospace from 1999 through 2011. Design and development The G200 was originally named "Astra Galaxy". When Gulfstream Aerospace purchased Galaxy Aerospace in 2001 the model was rebranded as the Gulfstream G200. Israel Aircraft Industries' subsidiary Galaxy Aerospace Inc. began designing the Galaxy in the late 1980s in a risk-sharing partnership with the Soviet aircraft design bureau Yakovlev OKB.Gunston, Bill and Yefim Gordon. ''Yakovlev Aircraft since 1924''. London, UK: Putnam Aeronautical Books, 1997. . The program officially launched in September 1993. Yakovlev handled design and manufacturing of the forward fuselage and empennage. However, the Russian company had trouble meeting agreed production schedules, and the partnership was ended in 1995. This led to another risk-sharing agreement, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yakovlev Yak-77
The Yakovlev Yak-77 was a planned large business or regional commuter jet. Work began in 1992, but no prototype was ever produced. History The Yakovlev Yak-77 was to have been a large business jet and regional commuter, considerably larger than the earlier Yakovlev Yak-48. Little information has been released about this design. Development Work on the Yak-77 began in 1992, the project manager being S A Yakovlev. The aircraft was to have two AE 3010/12 turbofans, uprated members of the Allison 3000 family of two-shaft turbofans, each with a takeoff rating of 4,500 kg (9,920 lb). Avionics were to have been a Collins Pro Line 4 system. In configuration for a business jet, the aircraft would have had seating for eight in a generous cabin. Configured as a regional commuter it would have seated 32 in rows of 2+2. Streatched versions with seating for up to 70 were studied. The aircraft was to have entered production at Saratov Saratov (, ; rus, Сара́тов, a=Ru-Sar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Yakovlev Yak-40
The Yakovlev Yak-40 (russian: Яковлев Як-40; NATO reporting name: Codling) is a regional jet designed by Yakovlev. The trijet's maiden flight was in 1966, and it was in production from 1967 to 1981. Introduced in September 1968, the Yak-40 has been exported since 1970. Development By the early 1960s, Soviet international and internal trunk routes were served by Aeroflot, the state airline, using jet or turboprop powered airliners, but their local services, many of which operated from grass airfields, were served by obsolete piston-engine aircraft such as the Ilyushin Il-12, Il-14 and Lisunov Li-2.Stroud 1968, p. 269–270. Aeroflot wanted to replace these elderly airliners with a turbine-powered aircraft, with the Yakovlev design bureau being assigned to design it. High speed was not required, but it would have to be able to operate safely and reliably out of poorly equipped airports with short (less than 700 m or 2,300 ft) unpaved runways in poor weather.Gunsto ...

Embraer E-Jets
The Embraer E-Jet family is a series of four-abreast narrow-body short- to medium-range twin-engine jet airliners designed and produced by the Brazilian aerospace manufacturer Embraer. The E-Jet was designed as a complement to the preceding ERJ family, Embraer's first jet-powered regional jet; designed to carry between 66 and 124 passengers, it was larger than any prior aircraft built by the company. The project's existence was revealed in early 1997, and was formally introduced at the Paris Air Show two years later. On 19 February 2002, the first prototype E-Jet conducted its maiden flight; later that year, quantity production of the type commenced. In early March 2004, the first E170 deliveries were made to LOT Polish Airlines. The E-Jet series has been a commercial success primarily due to its ability to efficiently serve lower-demand routes while offering many of the same amenities and features of larger jets. Initial teething issues, including hydraulic and engine-specifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
