The GE27 was developed in the early 1980s under the "Modern Technology Demonstrator Engines" (MTDE) program sponsored by the United States Army Aviation Applied Technology Directorate. Sporting a 22:1 pressure ratio, which was a record for single-spool compressors at the time, the GE27 was GE's unsuccessful submission to power the Bell Boeing V-22 Osprey tiltrotor aircraft.
