RTX completes preliminary design review of hybrid-electric GTF engine demonstrator

RTX has completed the preliminary design review for the GTF hybrid-electric propulsion demonstrator. The engine is a combination of two Collins Aerospace megawatt-class electric motor generators within a Pratt & Whitney GTF engine. RTX said the hybrid-electric propulsion system aims to enhance engine efficiency across all phases of flight and reduce fuel burn as well as emissions for future short- and medium-range aircraft. At a press event at the Farnborough International Airshow, the company said the engine is still in its “infancy stage”. It is part of RTX’s SWITCH project, supported by the European Union’s Clean Aviation programme. “Completing the
