Source: Pratt & Whitney Hybrid-electric propulsion technology has potential to increase efficiency and reduce emissions for future aircraft applications RTX  announced the completion of the preliminary design review for the hybrid-electric propulsion demonstrator engine being developed as part of the SWITCH project, supported by the European Union's Clean Aviation Joint Undertaking (Clean Aviation). By combining two Collins Aerospace megawatt-class electric motor generators within a Pratt & Whitney GTF™ engine, the hybrid-electric propulsion system aims to enhance engine efficiency across all phases of flight, offering the potential to reduce fuel burn and emissions for future short- and medium-range aircraft. "Completing the preliminary design review is a significant milestone toward demonstrating the potential of hybrid-electric technology to further enhance the performance and [...]

Source: Pratt & Whitney Swiss shop becomes the 17th active facility in growing GTF MRO network Pratt & Whitney, an RTX business, and SR Technics announced today the induction of the first Pratt & Whitney GTF™ engine at the MRO service provider's Zurich-based facility. SR Technics will provide full disassembly, assembly and test capability for the PW1100G-JM engine for the Airbus A320neo aircraft family. "Today, we extend our relationship with SR Technics, which began 35 years ago with maintenance on the PW4000 engine," said Marc Meredith, vice president of commercial aftermarket for GTF engines at Pratt & Whitney. "With their top-tier performance history, SR Technics will continue to deliver industry-leading services providing vital support for the expanding GTF fleet." Pratt [...]
