This milestone marks another important step as the program works to begin flight testing in 2024, John Pullen reports for Avionics International.

ARLINGTON, Va. - American aerospace company Raytheon Technologies is doing its part to help the aviation industry reach its goal of sustainable air travel. In addition to funding other companies focused on developing hybrid-electric propulsion systems via its venture capital firm RTX Ventures, Raytheon recently completed the first engine run of its regional hybrid-electric demonstrator, John Pullen reports for Avionics InternationalContinue reading original article.

The Military & Aerospace Electronics take:

12 January 2022 - “Aviation is moving toward a greener, cleaner future. Our partnership with NASA on HyTEC will allow Pratt & Whitney engineers to explore new technologies that will help make future aircraft propulsion systems even more sustainable,” said Geoff Hunt, senior vice president, Engineering and Technology, at Pratt & Whitney. “The use of SAF blends is increasing today to 50% and will reach 100% within a few years. This is a key pathway to achieving the industry’s goal of net zero carbon emissions by 2050. Our engine technology continues to improve in efficiency – flying further, with more power and on less fuel. This award helps Pratt & Whitney continue to ensure we develop advanced propulsion technologies that will be ready for the next-generation aircraft in the next decade.”

In October 2021, NASA awarded Pratt & Whitney two contracts under the HyTEC project to develop technologies for a high-pressure turbine that will include next generation ceramic matrix composites (CMC) materials capable of operating at higher temperatures than current CMCs, environmental barrier coatings, and advanced cooling and aerodynamic approaches that will enable new component designs and efficiencies.

In the second phase of the HyTEC project, Pratt & Whitney plans to demonstrate a technology-infused core comprised of a high-pressure compressor, high-pressure turbine, and combustor leveraging successes from the first generation GTF core. This phase is planned for 2024 through 2027 and will provide critical learning and increased maturation of the core prior to the next program launch.
