Pratt & Whitney Canada and ATR are collaborating to explore a mild hybrid version of the PW127XT engine for ATR's upcoming Evo turboprop, scheduled for release in 2035. This partnership aims to enhance the regional aircraft's efficiency by contributing up to 10% 2MW peak output, aiding the thermal engine during takeoff and climb phases.
ATR is focusing on a hybrid architecture that integrates an improved 200kW electrical motor with a reduction gearbox. This setup could optimize the engine with a lower power rating, boosting aircraft efficiency. At the Paris Air Show, more details about this project were shared, highlighting a goal for at least a 20% reduction in overall fuel burn.
The plan includes adapting existing technology and conducting comprehensive studies between Pratt & Whitney Canada and ATR. Daniel Cuchet, ATR's senior vice-president of engineering, stated: "(This is) The development of advanced propulsion technology for regional turboprop aircraft. All this we do as a complete package for feeding the Evo, and this is what we are studying today with Pratt and also internally to ATR."
