XA100
The General Electric XA100 is an American adaptive cycle engine demonstrator being developed by General Electric (GE) for the Lockheed Martin F-35 Lightning II and form the basis for the propulsion system for the United States Air Force's sixth generation fighter program, the Next Generation Air Dominance (NGAD). The three-stream adaptive cycle design can direct air to the bypass third stream for increased fuel efficiency and cooling or to the core and fan streams for additional thrust and performance. The thrust class engine is expected to be significantly more powerful and efficient than existing low-bypass turbofans. Development The U.S. Air Force and U.S. Navy began pursuing adaptive cycle engine in 2007 with the Adaptive Versatile Engine Technology (ADVENT) program, a part of the larger Versatile Affordable Advanced Turbine Engines (VAATE) program. This technology research program was then followed by the Adaptive Engine Technology Demonstrator (AETD) program in 2012, whi ...

Lockheed Martin F-35 Lightning II
The Lockheed Martin F-35 Lightning II is an American family of single-seat, single-engine, all-weather stealth multirole combat aircraft that is intended to perform both air superiority and strike missions. It is also able to provide electronic warfare and intelligence, surveillance, and reconnaissance capabilities. Lockheed Martin is the prime F-35 contractor, with principal partners Northrop Grumman and BAE Systems. The aircraft has three main variants: the conventional takeoff and landing (CTOL) F-35A, the short take-off and vertical-landing (STOVL) F-35B, and the carrier-based (CV/ CATOBAR) F-35C. The aircraft descends from the Lockheed Martin X-35, which in 2001 beat the Boeing X-32 to win the Joint Strike Fighter (JSF) program. Its development is principally funded by the United States, with additional funding from program partner countries from NATO and close U.S. allies, including the United Kingdom, Australia, Canada, Italy, Norway, Denmark, the Netherland ...

General Electric YF120
The General Electric YF120, internally designated as GE37, was a variable cycle afterburning turbofan engine designed by General Electric Aircraft Engines in the late 1980s and early 1990s for the United States Air Force's Advanced Tactical Fighter (ATF) program. It was designed to produce maximum thrust in the class. Prototype engines were installed in the two competing technology demonstrator aircraft, the Lockheed YF-22 and Northrop YF-23. Pratt & Whitney's competing F119 was selected over the F120 to power the ATF, the competition for which the Lockheed team won, and became F-22 Raptor. History Development General Electric (GE) began developing the GE37, which would become basis of the XF120 and YF120, for the Joint Advanced Fighter Engine (JAFE) program in the early 1980s aimed at supplying the powerplant for the Air Force's Advanced Tactical Fighter (ATF). The core technology used in the F120 design was developed during two industry-government programs, the Advanced Tech ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Adaptive Versatile Engine Technology
The ADaptive Versatile ENgine Technology (or ADVENT) program is an aircraft engine development program run by the United States Air Force with the goal of developing an efficient adaptive cycle, or variable cycle engine for next generation military aircraft in the 20,000 lbf (89 kN) thrust class. The program was succeeded by the Adaptive Engine Technology Demonstrator (AETD) program in 2012 and the Adaptive Engine Transition Program (AETP) in 2016, with the latter focused on developing and testing a 45,000 lbf (200 kN) thrust class adaptive cycle engine for next generation fighter aircraft and potential F-35 re-engining. Objective The objective of ADVENT is to develop an engine that is optimized for several design points, rather than the traditional single point. Instead of having an engine that is designed solely for high speed (like many current fighter engines are) or for high fuel efficiency (like many current commercial engines are), the final ADVENT eng ...

Adaptive Cycle Engine
A variable cycle engine (VCE), also referred to as adaptive cycle engine (ACE), is an aircraft jet engine that is designed to operate efficiently under mixed flight conditions, such as subsonic, transonic and supersonic. The next generation of supersonic transport (SST) may require some form of VCE. To keep aircraft drag at supercruise down, SST engines require a high specific thrust (net thrust/airflow) to keep the cross-sectional area of the powerplant to a minimum. This implies a high jet velocity not only at supersonic cruise, but at take-off, which makes the aircraft noisy. A high specific thrust engine has a high jet velocity by definition, as the following approximate equation for net thrust implies: :F_\text = \dot \left(V_\text - V_\text\right) where: : \dot = \fracm,\, intake mass flow rate : V_\text,\, fully expanded jet velocity (in the exhaust plume) : V_\text,\, aircraft flight velocity Rearranging the above equation, specific thrust is given by: : \frac = V_\ ...

WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. For e ...

Afterburner
An afterburner (or reheat in British English) is an additional combustion component used on some jet engines, mostly those on military supersonic aircraft. Its purpose is to increase thrust, usually for supersonic flight, takeoff, and combat. The afterburning process injects additional fuel into a combustor in the jet pipe behind (''i.e.'', "after") the turbine, "reheating" the exhaust gas. Afterburning significantly increases thrust as an alternative to using a bigger engine with its attendant weight penalty, but at the cost of increased fuel consumption (decreased fuel efficiency) which limits its use to short periods. This aircraft application of "reheat" contrasts with the meaning and implementation of "reheat" applicable to gas turbines driving electrical generators and which reduces fuel consumption. Jet engines are referred to as operating ''wet'' when afterburning and ''dry'' when not. An engine producing maximum thrust wet is at ''maximum power,'' while an engine ...
