The workings of a turbojet engine are based on fundamental physics, especially Newton's third law. Just like a balloon moves forward when air is released, a jet engine uses a high-velocity exhaust to ...

GE designed an operational variable-cycle engine in the late 1980s for the program that led to the F22. I think it was called the GE YF120 and flew in both the YF22 and the YF23 black widow.

Jet engines are a lot simpler than you might think although, ... “A Brayton cycle is simply compression, combustion, and expansion equals volume,” the video’s host notes, ...

These included the highest combined compressor and turbine temperature operation “in the history of jet engine propulsion.” GE’s adaptive cycle engine architecture is unique to the aero engine ...

This new system uses a version of the Brayton cycle, which jet engines also use to generate electricity and thrust. ... Most jet engines are powered by an open Brayton cycle.

But rival General Electric wants the Air Force to toss the F135 and re-engine with its own XA-100 adaptive cycle engine. Already, two flight weight XA100 prototypes completed testing in 2022.

GE Aerospace is getting an Air Force Life Cycle Management Center contract with a value of up to $203 million for work on new jet engine technologies, the Department of Defense said last week.

HOW GE’S HYPERSONIC ENGINE COMPARES TO OTHER DESIGNS. Last November, Atlanta-based aviation firm Hermeus demonstrated their turbine-based combined cycle Chimera engine could successfully ...
