4 terms

hybrid-electric propulsion system technical

"ground testing of the flight-standard propulsion system and propeller"

A hybrid-electric propulsion system combines a conventional engine (such as a gas turbine or internal-combustion engine) with one or more electric motors and batteries to move a vehicle, aircraft, or vessel. For investors, it matters because it can lower fuel and operating costs, reduce regulatory and environmental risk, and open new market demand—similar to a car that can switch between gas and electric power to save money and meet emissions rules.

motor controller technical

"a 1-megawatt electric motor and motor controller developed by RTX's Collins Aerospace"

A motor controller is an electronic device that governs the speed, torque, direction, and braking of an electric motor by regulating power flow and signals. Think of it as the car's transmission and accelerator for machines: it determines how smoothly and efficiently a motor performs, which matters to investors because controller design affects product performance, energy use, manufacturing cost, reliability, and compliance with safety or efficiency standards.

thermal engine technical

"combines an advanced Pratt & Whitney Canada thermal engine with a 1-megawatt electric motor"

A thermal engine is a machine that converts heat into mechanical work by moving energy from a hot source to a cold sink through a working fluid or material. Think of it like a water wheel driven by hot and cold temperatures instead of flowing water. Investors care because thermal engines determine fuel and energy efficiency, operating costs, and emissions for industries such as power generation, transportation, and manufacturing, which affect profitability and valuation.

regional turboprop mission technical

"for a typical 250-nautical-mile regional turboprop mission"

A regional turboprop mission is a flight operation using a turboprop-powered aircraft on short to medium regional routes, characterized by specific stage lengths, passenger or cargo loads, frequency, and turnaround times. For investors, it matters because the mission profile drives fuel use, maintenance, seating capacity and hourly costs—similar to choosing a delivery van versus a small car for local runs—so it influences airline route economics, fleet choices and asset value.

Ground testing of flight-standard engine and propeller for RTX Hybrid-Electric Flight Demonstrator begins in Quebec

LONDON, July 21, 2026 /PRNewswire/ -- Farnborough International Airshow – Pratt & Whitney Canada today announced a new phase in the RTX Hybrid-Electric Flight Demonstrator project, with ground testing of the flight-standard propulsion system and propeller in Longueuil, Quebec. Following completion of the ground test, the hybrid-electric propulsion system will be installed on the De Havilland Canada Dash 8-100 experimental aircraft, with the first flight expected in 2027. Pratt & Whitney is an RTX (NYSE: RTX) business.

"Assembling the final, flight-standard propulsion system brings us one step closer to proving hybrid-electric technology in flight," said Jean Thomassin, executive director, New Products and Services Introduction, Pratt & Whitney Canada. "We are advancing thermal engine and hybrid-electric technologies which could enhance fuel efficiency and performance for a wide range of future aircraft applications."

The hybrid-electric propulsion system combines an advanced Pratt & Whitney Canada thermal engine with a 1-megawatt electric motor and motor controller developed by RTX's Collins Aerospace, along with a battery system supplied by H55 S.A., a Swiss developer of certifiable aviation energy storage systems.

With the electric motor providing additional power during demanding flight phases such as takeoff and climb, the hybrid-electric architecture enables the propulsion system to operate more efficiently throughout the flight mission. The project aims to demonstrate up to 30% improved fuel efficiency for a typical 250-nautical-mile regional turboprop mission.

The RTX Hybrid-Electric Flight Demonstrator project has accelerated collaboration between leading aerospace industry companies and research institutions within Canada and abroad, including De Havilland Aircraft of Canada, GKN Aerospace, AeroTEC, Ricardo, the National Research Council of Canada and the Innovative Vehicle Institute.

The project is supported by the governments of Canada and Quebec. Additionally, the project's propulsion system verification phase is supported by Strix, the organization managing Canada's Initiative for Sustainable Aviation Technology (INSAT), with funding from the Government of Canada, as part of its fifth wave of innovative research projects.
