Guy is a Senior Editor for Aviation Week, based in Colorado Springs. Before joining Aviation Week in 2007, Guy was with Flight International, first as technical editor based in the U.K. and most recently as U.S. West Coast editor. Before joining Flight, he was London correspondent for Interavia, part of Jane's Information Group.
In 2013 the Jesse H. Neal award for Best Technical Content was awarded to Guy Norris and Graham Warwick for their Advanced Propulsion feature. He received the 2015 Lauren D. Lyman Award for outstanding achievement in aerospace communications. And in 2018 he was awarded Technology Writer of the Year by the judges of the Aerospace Media Awards.
Guy is also a multiple winner of the Royal Aeronautical Society Aerospace Journalist of the Year Award in the Air Transport, Propulsion and Systems/Technology categories, and in 2006 he received the Royal Aeronautical Society Decade of Excellence Award for sustained achievement in aerospace journalism.
Amongst other works Guy has authored the aerospace section of a science encyclopedia and co-authored, and produced an educational aviation CD-ROM. Guy has also authored more than a dozen books on the histories of Airbus, Boeing and other airframe manufacturers.
IntercooledIn an intercooled engine, air exiting the low-pressure (LP) compressor is cooled before entering the high-pressure (HP) compressor using bypass air scooped into a set of heat exchangers nested around the engine core. The cooled air has lower combustor entry temperatures, thereby lowering flame temperatures which, in turn, reduce NOx emissions. The overall thermodynamic efficiency is also improved because the relative temperature rise in the combustor is bigger for a given turbine entry temperature (TET).
Various forms of unsteady or pulse detonation combustion in the future could feature turbine-based combined cycle (TBCC) engine concepts that form part of NASA’s ongoing studies into highly reliable, reusable launch systems.
General Electric is joining with NASA to revive studies of its long-abandoned GE36 unducted fan, or “open rotor” and is simultaneously launching a next-generation CF34 technology effort as part of a pressing drive to develop families of fuel-saving engines.
