STEP-Tech will focus on the development of high voltage distributed turbine electric hybrid propulsion concepts in the 150-500 kW scale, and can be scaled up to 1 MW and beyond. The modularity and extensibility of the STEP-Tech validation platform makes it possible to quickly build prototypes and validate against a wide range of configurations. After completing a proof of concept earlier this year, ground testing of the platform is scheduled to begin in late 2022. "Innovation has always been at the heart of Pratt & Whitney," said Geoff Hunt, Senior Vice President of Engineering and Technology at Pratt & Whitney. We are very excited to expand our exploration of hybrid technology by working closely with Collins. Hybrid technology has great potential not only to unlock greater efficiency for future aircraft, but also to support emerging advanced air traffic solutions. Our continued pursuit of advanced propulsion technologies will ultimately drive aviation on a path to net zero carbon emissions by 2050."
(The STEP-Tech demonstration platform covers a variety of potential applications, including advanced air motor vehicles, high-speed eVTOL, and hybrid wing body aircraft.)
The STEP-Tech validation platform will include complete end-to-end system capabilities, including high efficiency turbo generators, energy storage, power electronics, and modular electric thrusters. The successfully proven technology can be implemented in a range of new aircraft applications, including high-speed EVtoLs, small and medium unmanned aerial vehicles (UAVs), and small and medium commercial aviation transport aircraft. Henry Brooks, President of Collins Aerospace Power and Controls, said, "With Pratt & Whitney's proven track record in aerospace propulsion and Collins' legacy of innovation in power systems, we are extremely well positioned to lead the development of hybrid technologies for a new generation of sustainable aircraft. Our verifiers program will help mature the technology and components for applications ranging from small EvtoLs and regional turboprops to single-aisle aircraft."
Existing partnerships between Pratt & Whitney and Collins on hybrid technology include products based on German? Flight verification aircraft for the Havilland 8-100 turboprop regional jet. Hybrid electric propulsion systems offer the opportunity to optimize engine performance at different stages of flight, resulting in greater fuel efficiency and lower CO2 emissions across a range of different aircraft classes. Hybrid technology is also highly scalable, meaning that the electrical components and electrical control systems developed as part of the announced verifier could eventually support larger scale applications, including single-aisle commercial aircraft.
