Pratt Canada Picks Battery Supplier for Hybrid-Electric Project


Pratt & Whitney Canada (P&WC) has picked out Switzerland’s H55 to offer battery units for the engine company’s regional hybrid-electric flight demonstrator method, P&WC explained Thursday. The development of the battery element patterns and affiliated electrical management methods will also attract aid from the Countrywide Investigate Council Canada (NRC) and the province of Quebec’s Ground breaking Automobile Institute (IVI).

A spinoff from Solar Impulse, the to start with electric powered plane to fly all over the world, H55 develops modular, light-weight propulsion and strength storage techniques for electric powered plane this sort of as the eBeaver, now under growth by Western Canadian seaplane operator Harbour Air.

“We’re delighted to draw from H55’s engineering in the field of aircraft battery programs and collaborate with NRC and IVI on optimizing the design and style for our hybrid-electric flight demonstrator plan,” reported Jean Thomassin, Pratt Canada’s government director of new solutions and expert services. “Hybrid-electric know-how holds important prospective to increase the efficiency of next-generation plane propulsion systems, letting us to established new requirements for sustainability for regional and commuter aircraft.”

H55 joins the P&WC-led program some ten months immediately after the governments of Canada and Quebec fully commited to contributing about 50 % of a C$163 million expense in the hybrid-electrical propulsion technological know-how for a Dash 8-100 flight demonstrator scheduled to commence ground testing late this 12 months and fly in 2024.

P&WC targets a 30 % improvement in gasoline efficiency and commensurate reduction in CO2 emissions, when compared with today’s most sophisticated turboprop engines for regional aircraft. Fellow Raytheon subsidiary Collins Aerospace will supply the 1 megawatt electric powered motor for the hybrid-electrical propulsion procedure.

The NRC’s contributions will include things like supporting the development of the high-voltage battery sub-programs and their linked elements. In the meantime, IVI will support progress work to optimize the structure and integration of the battery and manage programs on the Dash 8 experimental plane.

Pratt & Whitney phone calls hybrid-electrical propulsion technological innovation a main component of its method for advancing the efficiency of aircraft propulsion units in assist of the sector-vast target of attaining net-zero CO2 emissions for aviation by 2050. The company’s engineering improvement routines also include the advancement of sustainable aviation fuels (SAFs) and hydrogen, each of which can profit from the greater efficiencies enabled by hybrid-electric powered propulsion techniques.
