Collins Aerospace lab completes Clean Aviation SWITCH testing and moves on to LEIA project LONDON, July 22, 2026 /PRNewswire/ -- Farnborough International Air Show – Collins Aerospace, an RTX (NYSE: RTX ) business, has completed integrated lab testing for the European Union's Clean Aviation SWITCH project at The Grid , its advanced electric power systems lab in Rockford, Ill. The tested hybrid-electric powertrain subsystems, which successfully operated with simulated aircraft and engine systems, are now headed to Airbus's laboratories for further aircraft level integration testing, including work on aircraft design, battery interfacing and energy-management systems. "This is the largest integrated systems test conducted at The Grid since its opening in 2023," said Kristin Smith, vice president of Electric Power Systems at Collins Aerospace. "By combining our technology expertise with deep industry collaboration, we are demonstrating how hybrid-electric systems can significantly reduce fuel consumption for next-generation aircraft." SWITCH aims to improve engine efficiency for future short- and medium-range aircraft by integrating hybrid-electric systems on a Pratt & Whitney GTF™ engine, including two Collins megawatt class motor generators and controllers. Testing at The Grid was supported by Pratt & Whitney teams who performed powertrain system integration and supplied the...
