Raytheon Technologies’ Pratt and Whitney & Collins Aerospace divisions have made significant progress in advancing hybrid-electric power with the demonstration of Scalable Turboelectric Powertrain Technology (STEP-Tech), which completed the first engine run and electric system integration test.
As a modular and scalable demonstration platform, STEP-Tech offers rapid prototyping of distributed intelligence concepts for next-generation applications, including advanced aerial vehicles, high-speed EVs and hybrid wing-body aircraft, Rayton said.
Raytheon Technologies’ core technology is a key component of Raytheon’s technology roadmap to increase efficiency in many future aircraft applications, from advanced air mobility to regional aircraft and single aisles, he said. Officer Mark Russell.

Raytheon Technologies said the successful test at Raytheon Technologies’ research center in East Hartford, Connecticut included the first run of a partially powered STEP-Tech turbogenerator. An electrical system experiment where battery and supercapacitor energy storage systems are integrated with a high-voltage transmission system followed. The next test involved a full power turbogenerator run and checking of the propellers.
With support from the governments of Canada and Quebec, Raytheon Technologies is developing hybrid-electric power as part of a hybrid-electric flight demonstration program. The work also includes a sustainable water-injection turbofan in collaboration with the European Union’s Clean Aviation Convention.

Through such demonstration programs, Raytheon Technologies aims to develop a broad portfolio of sustainable aviation technologies in collaboration with its business units and industry and public-private partnerships. The strategy includes enabling continued aircraft efficiency and widespread use of sustainable aviation fuel (SAF) to support civil aviation’s net-zero CO goal.2 Release in 2050
