Pratt & Whitney Canada, with support from Canada’s Initiative for Sustainable Aviation Technology (Insat), is embarking on the 'hydrogen advanced design engine study' (HyADES) to demonstrate hydrogen combustion technology on a PW127XT regional turboprop engine. The collaboration with Next Hydrogen Solutions Inc aims to develop high-efficiency low-cost electrolysers for hydrogen production infrastructure. This project reflects Pratt & Whitney Canada's commitment to advancing aviation sustainability through various pathways, including engine efficiency enhancements, hybrid-electric propulsion, and sustainable aviation fuel compatibility. The initiative targets regional aviation as a promising sector for hydrogen adoption while showcasing the adaptability of the PW127XT engine to operate with low-carbon alternative fuels. Funding will initially support fuel nozzle and combustor rig testing with hydrogen, with future plans for full engine ground testing. Concurrently, Pratt & Whitney Canada is involved in the turbine engine advanced materials for efficiency (TEAME) project in collaboration with Derivation Research Laboratory (DRL) to explore materials for gas turbine engines that enhance efficiency and reduce emissions. The PW127XT engine, known for its fuel efficiency, reliability, and reduced maintenance costs, continues to prove its leadership in the turboprop engine segment. The broader efforts by Pratt & Whitney Canada and its partners underscore a commitment to driving innovation and sustainability in the aviation industry.
