WRIGHT-PATTERSON AIR FORCE BASE, Ohio (AFNEWS) -- Air Force Research Laboratory engineers have outlined a five-year timeline for a new, adaptive engine that will enable pilots to switch from high speed combat maneuvers to long-range persistence mode as effortlessly as a bird in flight.
AFRL's Propulsion Directorate recently issued a Broad Agency Announcement calling for industry to develop a demonstration program for the revolutionary engine, called Adaptive Versatile Engine Technology, or ADVENT.
Also known as Project ADVENT, the program's goals are to develop inlet, engine and exhaust technologies that optimize propulsion system performance over a broad range of altitude and speed.

My guess on what they might be studying is the concept of Variable Bypass engines. It is well known that the mose fuel efficient Jets use High bypass engines like Turbofans or even turboprops. High speed aircraft either use very low bypass engines, like the F-119's on the F-22, or Turbojets like the J-58's that flew on the Blackbird Spyplane. If they could find a way to combine the advantages of both types into one engine, that would be a major advance in engine technology.
