“The F-35 is the most advanced fighter yet built, but decisions and compromises imposed on it more than a decade ago continue to push up its cost, decrease its reliability, limit its performance, and constrain its ability to exploit new technologies. For fighter pilots of ...
Congress should direct the Pentagon to break out the F-35’s propulsion upgrade from the rest of the program to better to track its scope, schedule, and cost, the Government Accountability Office urged in a new May 30 report. Meanwhile, engine-maker Pratt & Whitney added its ...
The Air Force couldn't find a place for Adaptive Engine Technology Program powerplants on the F-35 in its fiscal 2024 budget request, opting to harvest what it can from its $4 billion investment and press on to the Next-Generation Advanced Propulsion program.
If the Air Force and Pentagon decide the F-35 fighter needs an all-new engine, it wouldn’t just give the jet range and performance improvements—it would drive a refresh of the entire fighter propulsion industrial base, a GE Aerospace official claimed Feb. 16. Competitor Pratt & ...
Generational improvements to combat propulsion performance have never been more pressing for the U.S. as it seeks to ensure continued air dominance in tempestuous theaters like the Indo-Pacific. GE Aerospace's XA100 is the most advanced combat engine in the world, and if implemented it would ...
Nearly 50 members of Congress have urged Defense Secretary Lloyd J. Austin III to fund a new phase of development for advanced fighter engines in the fiscal 2024 budget, sending a letter to the Pentagon on Oct. 7. The letter, signed by 49 lawmakers from ...
GE Aviation announced that it completed milestone tests for the engine it hopes will power Air Force fighters well into the future. GE calls its offering in the Adaptive Engine Transition Program the XA100, and the company hopes the Air Force will soon select it ...
GE’s AETP offering, called the XA100, delivers 25% better fuel efficiency, twice the thermal management capacity, and at least 10% more thrust than the existing F-35 engine. The XA100’s three test campaigns—including one currently taking place at the Air Force’s Arnold Engineering Development Complex (AEDC)—have ...
In 1941, Gen. Henry H. “Hap” Arnold of the then-U.S. Army Air Corps, personally reviewed a jet engine patented by Sir Frank Whittle flying on a Gloster E.28/39 aircraft. Impressed by its design, Arnold arranged for a Whittle engine to be brought back to the ...
Fighter jet engines are an inherent compromise. If you want more power, you pay by giving up range. Want more range? It's going to cost you in power. Each generation of jet engines has dealt with this unbreakable rule. But maybe there really is another ...
Pratt & Whitney is testing its Adaptive Engine Technology Program XA101 powerplant and has already demonstrated the objective goals for the program, company military engines president Matthew Bromberg said. He estimates that up to 70 percent of the technology could be fitted to improve fighter ...
Engine makers should be able to meet House defense policy bill language calling for a new F-35 powerplant based on the Adaptive Engine Transition Program by 2027, but only for the conventional takeoff versions, a GE Aviation executive said. “We would be eager to step ...
