The Superjet: Engineers at GE Aviation Are Building the Ultimate Jet Engine | GE Reports
Thing is, the tech path for this leads to a similar family of engines, like the J58 that powers the SR-71 (two path engine with outer duct not behind a compressor and used as a ramjet), and SERJ (technically a two path where you have part of the compressor flow go to a combustor and turbine segment, while the rest flows to a ramjet combustor only). Probably the basic difference between ADVENT and SERJ is a lack of subsonic ramjet combustor and an air bleed path.

Interesting research by the japanese to use a gas generator/ultra high bypass ratio turbine to drive clusters of multi stage recycling tip turbine driven lift fans for VTOL lift.
