Pratt & Whitney Canada PW127XT fuel nozzle and combustor testing
Pratt & Whitney Canada is testing fuel nozzle and combustors for hydrogen combustion on its PW127XT regional airliner turboprop engine.

Pratt & Whitney Canada is preparing to demonstrate hydrogen combustion technology on a PW127XT turboprop engine as part of the Canadian government’s Initiative for Sustainable Aviation Technology (INSAT). On November 6, the RTX group company said the Hydrogen Advanced Design Engine Study (HyADES) will be conducted in partnership with Next Hydrogen Solutions, which is developing high-efficiency, low-cost electrolyzers for the hydrogen production process.

Funding for the first phase of work covers fuel nozzle and combustor rig testing using hydrogen fuel, with future phases involving engine ground tests. The PW127XT is the latest member of Pratt & Whitney’s PW100 series of engines that have accumulated more than 220 million flight hours on a variety of regional airliners.
