GE Aviation and NASA will run a wind tunnel test program over the northern summer to evaluate and test counter-rotating fan-blade systems for open-rotor jet engine designs. The newly improved rig for testing was originally used by GE and NASA in the 1980s on scale models of counter-rotating fan systems, which led to the development of the GE36 engine. The test program also demonstrated that an open-rotor jet engine consumed 30 percent less fuel compared to similar-sized conventional jet engines. Just think what a 30 percent drop in fuel consumption would deliver today, not only to an airline industry struggling to keep ticket prices down, but also the positive benefits to the environment.
