Integrated High Performance Turbine Engine Technology
The Integrated High Performance Turbine Engine Technology program was a project of the United States military. Its objective was to conduct science and technology research that would secure advancements in the engineering of the gas turbine engines used in military aircraft. It ran from 1987 until 2005. IHPTET designated goals in each of three engine classes: turbofan/turbojet, turboprop/turboshaft, and expendable engines. For the turbofan class the primary goal was to double the engine thrust-to-weight ratio. The program made many significant developments which have been employed in such aircraft as the F-35 / Joint Strike Fighter. It was firmly regarded as successful although it did not fully achieve its explicit goals. It was succeeded by the Versatile Affordable Advanced Turbine Engines (VAATE) program.

London is the capital and largest city of England and the United Kingdom, with a population of just under 9 million. It stands on the River Thames in south-east England at the head of a estuary down to the North Sea, and has been a major settlement for two millennia. The City of London, its ancient core and financial centre, was founded by the Romans as '' Londinium'' and retains its medieval boundaries.See also: Independent city ยง National capitals The City of Westminster, to the west of the City of London, has for centuries hosted the national government and parliament. Since the 19th century, the name "London" has also referred to the metropolis around this core, historically split between the counties of Middlesex, Essex, Surrey, Kent, and Hertfordshire, which largely comprises Greater London, governed by the Greater London Authority.The Greater London Authority consists of the Mayor of London and the London Assembly.

National Academies Press
The US National Academies Press (NAP) was created to publish the reports issued by the National Academies of Sciences, Engineering, and Medicine, the National Academy of Engineering, the National Academy of Medicine, and the National Research Council. It publishes nearly 200 books a year on a wide range of topics in the sciences. The NAP's stated mission is seemingly self-contradictory: to disseminate as widely as possible the works of the National Academies of Sciences, Engineering, and Medicine, and to be financially self-sustaining through sales. This mission has led to great experimentation in openness regarding online publishing. The National Academy Press (as it was known in 1993) was the first self-sustaining publisher to make its material available on the Web, for free, in an open access model. By 1997, 1000 reports were available as sequential page images (starting with i, then ii, then iii, then iv...), with a minimal navigational envelope. Their experience up to 1998 ...

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 ...

Advanced Affordable Turbine Engine
The Improved Turbine Engine Program (ITEP), formerly the Advanced Affordable Turbine Engine (AATE) program, is a United States Army project to develop a General Electric T700 replacement for the UH-60 Black Hawk and AH-64 Apache, improving fuel consumption, power, durability and cost. Honeywell and Pratt & Whitney formed the ATEC joint venture to develop the T900, while GE Aviation builds the T901. In February 2019, the US Army selected the GE T901 as the winner of the program. History In December 2006, the U.S. Army's Aviation Applied Technology Directorate (AATD) solicited proposals for the 3000 shp ''Advanced Affordable Turbine Engine'' (AATE) free-turbine turboshaft to replace the GE T700 that currently power the UH-60 Black Hawk and AH-64 Apache rotorcraft, leveraging the DoD/NASA/ DOE VAATE program. Refitting the existing fleet of twin-engine Black Hawks and Apaches would require a total of 6,215 engines, including spares. Any aircraft that currently uses the T700 ...

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 Netherlands ...

United States Military
The United States Armed Forces are the military forces of the United States. The armed forces consists of six service branches: the Army, Marine Corps, Navy, Air Force, Space Force, and Coast Guard. The president of the United States is the commander-in-chief of the armed forces and forms military policy with the Department of Defense (DoD) and Department of Homeland Security (DHS), both federal executive departments, acting as the principal organs by which military policy is carried out. All six armed services are among the eight uniformed services of the United States. From their inception during the American Revolutionary War, the U.S. Armed Forces have played a decisive role in the history of the United States. They helped forge a sense of national unity and identity through victories in the First Barbary War and the Second Barbary War. They played a critical role in the American Civil War, keeping the Confederacy from seceding from the republic and preserving the unio ...

Thrust-to-weight Ratio
Thrust-to-weight ratio is a dimensionless ratio of thrust to weight of a rocket, jet engine, propeller engine, or a vehicle propelled by such an engine that is an indicator of the performance of the engine or vehicle. The instantaneous thrust-to-weight ratio of a vehicle varies continually during operation due to progressive consumption of fuel or propellant and in some cases a gravity gradient. The thrust-to-weight ratio based on initial thrust and weight is often published and used as a figure of merit for quantitative comparison of a vehicle's initial performance. Calculation The thrust-to-weight ratio is calculated by dividing the thrust (in SI units – in newtons) by the weight (in newtons) of the engine or vehicle. Note that the thrust can also be measured in pound-force (lbf), provided the weight is measured in pounds (lb). Division using these two values still gives the numerically correct (dimensionless) thrust-to-weight ratio. For valid comparison of the initial th ...
