INNOVATIONS UNVEILED during July's searingly hot Farnborough International Airshow emphatically showed aerospace's ongoing push towards sustainability.There were numerous electric, hybrid-electric and hydrogen aviation announcements.Airbus and CFM International will use an A380 to test the CFM RISE (Revolutionary Innovation for Sustainable Engine) open rotor design to study engine/wing integration, aerodynamic performance and emissions.Raytheon units Pratt & Whitney and Collins Aerospace announced the Scalable Turboelectric Powertrain Technology, a new hybrid-electric demonstrator to develop high-voltage distributed turboelectric hybrid-electric propulsion concepts in the 100-500kW class. Ground tests will begin in late 2022. P&W has also started flight-testing GTF Advantage to further reduce fuel burn and emissions on the geared turbofan range powering A320s, A220s and E-Jet's E2sGE Aviation has completed first test of a megawatt-class and multi-kilovolt hybridelectric propulsion system in altitude conditions, simulating a single-aisle commercial flight, in NASA's Electric Aircraft Testbed facility in Sandusky, Ohio.
