TF34
The General Electric TF34 is an American military turbofan engine used on the A-10 Thunderbolt II, S-3 Viking and RQ-170 Sentinel. Design and development Developed by GE Aircraft Engines during the late 1960s, the original engine comprises a single stage fan, driven by a 4-stage low pressure (LP) turbine, supercharging a 14-stage high pressure (HP) compressor, driven by a 2-stage HP turbine. An annular combustor is featured. The TF34-GE-400A is rated at 9,275 lbf (41.26 kN) static thrust. The civilian variant, the CF34, is used on a number of business and regional jets. Variants ;TF34-GE-2 Initial variant for Lockheed S-3, entered production in August 1972. ;TF34-GE-100 Variant for Fairchild A-10A, first flown in A-10 during May 1972.

General Electric CF34
The General Electric CF34 is a civilian high-bypass turbofan developed by GE Aviation from its TF34 military engine. The CF34 is used on a number of business and regional jets, including the Bombardier CRJ series, the Embraer E-Jets, and Comac ARJ21/C909. In 2012, there were 5,600 engines in service. Design and development The original engine contained a single stage fan driven by a 4-stage low pressure (LP) turbine, supercharging a 14-stage high pressure (HP) compressor driven by a 2-stage HP turbine, with an annular combustor. Later higher thrust versions of the CF34 feature an advanced technology core, with only 10 HP compressor stages. Latest variants, the and , were derived from the CFM56 engine family, and have a radically different HP spool, containing a 9-stage compressor driven by a single stage turbine. The LP spool has 3 core booster stages behind the fan. Static thrust is for the variant. On wing times can reach 14,000 hours, an overhaul costs over $1. ...

RQ-170 Sentinel
The Lockheed Martin RQ-170 Sentinel, nicknamed Wraith, is an American unmanned aerial vehicle (UAV) developed by Lockheed Martin and operated by the United States Air Force (USAF) for the Central Intelligence Agency (CIA). While the USAF has released few details on the UAV's design or capabilities, defense analysts believe that it is a stealth aircraft fitted with aerial reconnaissance equipment. Introduced in 2007, it was deployed to Afghanistan in late 2007, and to South Korea two years later, in September 2009. Some images and details of the aircraft were released after Iran captured an RQ-170 in 2011. It has a flying wing design, and uses a single engine, speculated to be either a General Electric TF34 turbofan or a Garrett TFE731. Development The RQ-170 Sentinel was developed by Lockheed Martin's Skunk Works as a stealth unmanned aerial vehicle (UAV). Journalists have noted design similarities between the RQ-170 and previous stealth and UAV programs such as the Lock ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
General Electric Aircraft Engines
General Electric Company, doing business as GE Aerospace, is an American aircraft engine supplier that is headquartered in Evendale, Ohio, outside Cincinnati. It is the legal successor to the original General Electric Company founded in 1892, which split into three separate companies between November 2021 and April 2024, adopting the trade name GE Aerospace after divesting its healthcare and energy divisions. GE Aerospace both manufactures engines under its name and partners with other manufacturers to produce engines. CFM International, the world's leading supplier of aircraft engines and GE's most successful partnership, is a 50/50 joint venture with the French company Safran Aircraft Engines. As of 2020, CFM International holds 39% of the world's commercial aircraft engine market share (while GE Aerospace itself holds a further 14%). GE Aerospace's main competitors in the engine market are Pratt & Whitney and Rolls-Royce. The division operated under the name of General Elec ...

A-10 Thunderbolt II
The Fairchild Republic A-10 , also infamously known under the nickname , is a single-seat, twinjet, twin-turbofan, straight wing, straight-wing, Subsonic aircraft, subsonic attack aircraft developed by Fairchild Aircraft, Fairchild Republic for the United States Air Force (USAF). Initial operating capability, In service since 1977, it is named after the Republic P-47 Thunderbolt strike-fighter of World War II, but is instead commonly referred to as the "Warthog" (sometimes simply "Pig, Hog"). The A-10 was designed to provide close air support (CAS) to ground troops by attacking enemy armored vehicles, tanks, and other ground forces; it is the only production-built aircraft designed solely for CAS to have served with the U.S. Air Force. Its secondary mission is to direct other aircraft in attacks on ground targets, a role called forward air controller (FAC)-airborne; aircraft used primarily in this role are designated OA-10.

Lockheed S-3 Viking
The Lockheed S-3 Viking is a four-crew, twin-engine turbofan-powered jet aircraft designed and produced by the American aerospace manufacturer Lockheed Corporation. Because of its characteristic sound, it was nicknamed the "War Hoover" after the vacuum cleaner brand. The S-3 was developed in response to the VSX program conducted by the U.S. Navy (USN) to procure a successor anti-submarine warfare (ASW) aircraft to the Grumman S-2 Tracker. It was designed, with assistance from Ling-Temco-Vought (LTV), to be a carrier-based, subsonic, all-weather, long-range, multi-mission aircraft. On 21 January 1972, the prototype ''YS-3A'' performed the type's maiden flight. Upon entering regular service during February 1974, it proved to be a reliable workhorse. In the ASW role, the S-3 carried automated weapons and in-flight refueling gear. Further variants, such as the ''ES-3A Shadow'' carrier-based electronic intelligence (ELINT) platform, and the ''US-3A'' carrier-based utility a ...

Sikorsky S-72
The Sikorsky S-72 was an experimental Sikorsky Aircraft compound helicopter developed as the Rotor Systems Research Aircraft (RSRA) for the National Aeronautics and Space Administration (NASA) and the United States Army. The RSRA was a testbed for rotor and propulsion systems for high-speed. Design and development RSRA Sikorsky and Bell Helicopters competed for the RSRA contract. Bell's preferred proposal was the "Bell 646A" with rotors based on the Bell 240 UTTAS; the alternative was the smaller "Bell 646B" based on the Bell 309 KingCobra. Sikorsky proposed either a new aircraft or a modified Sikorsky S-67 Blackhawk with the rotor and gearbox from the Sikorsky S-61. Sikorsky won the contract for two aircraft in January 1974. The modified S-67 became the S-72. The S-72 could be fitted with wings and General Electric TF34 turbofans to allow compound helicopter configurations to be experimentally investigated at speeds up to . In addition, it could fly as a fixed-wing aircra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

High-bypass Turbofan
A turbofan or fanjet is a type of airbreathing jet engine that is widely used in aircraft propulsion. The word "turbofan" is a combination of references to the preceding generation engine technology of the turbojet and the additional fan stage. It consists of a gas turbine engine which achieves mechanical energy from combustion, and 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 jet thrust relative t ...
