Gizmag Comment Feed: GE and NASA to give open-rotor jet engine systems a spin http://www.gizmag.com 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.en gizmag.com Comment on 'GE and NASA to give open-rotor jet engine systems a spin' by Muraculous http://www.gizmag.com/ge-nasa-open-rotor-jet-engine-systems/11962/#comment-22936 http://www.gizmag.com/ge-nasa-open-rotor-jet-engine-systems/11962/#comment-22936 Wed, 19 May 2010 12:00:21 -0500 Comment on 'GE and NASA to give open-rotor jet engine systems a spin' by Gadgeteer http://www.gizmag.com/ge-nasa-open-rotor-jet-engine-systems/11962/#comment-3202 http://www.gizmag.com/ge-nasa-open-rotor-jet-engine-systems/11962/#comment-3202 Fri, 19 Jun 2009 23:52:19 -0500 Comment on 'GE and NASA to give open-rotor jet engine systems a spin' by Raino Sommer http://www.gizmag.com/ge-nasa-open-rotor-jet-engine-systems/11962/#comment-3097 http://www.gizmag.com/ge-nasa-open-rotor-jet-engine-systems/11962/#comment-3097 Wed, 17 Jun 2009 15:24:15 -0500
