As the Paris Air Show kicks off, ATR and RTX (parent of Pratt & Whitney) have announced a collaborative project to develop the next generation of turboprop engines. This partnership aims to push forward regional aviation by enhancing engine efficiency, integrating hybrid-electric propulsion, and modernizing aircraft design.
ATR, a joint venture between Airbus and Leonardo, currently builds the ATR 42-600 and ATR 72-600, powered by Pratt & Whitney Canada’s PW127XT engines—derivatives of the long-serving PW100 series. However, with propulsion technology evolving rapidly, the collaboration is set to move beyond the existing PW100 family, either by developing a heavily modified variant or a potentially clean-sheet engine design.
Key focuses for Pratt & Whitney Canada include increasing thermal efficiency, improving field performance, and utilizing advanced materials like carbon composites and ceramic matrix composites for enhanced durability and reduced weight. Simultaneously, ATR will work on nacelle design, airframe integration, and aerodynamic refinements, including new propeller technology and digital engine controls.
The broader initiative, dubbed ATR EVO, hints at significant aircraft upgrades: lighter cabins, thermal de-icing systems, FADEC, and most notably, a hybrid-electric propulsion system. If successful, this would make ATR the largest commercial aircraft line to deploy hybrid-electric power—potentially setting the stage for a revolution in regional air travel.
With De Havilland’s Dash 8 production paused and limited competition in this aircraft class, ATR is strategically positioned to lead. The ATR-RTX collaboration not only seeks performance and sustainability gains but also aims to redefine the future of regional aviation.
