Next Seminar PYCNIC: A Machine Learning Approach for Detecting Convergence of CFD Simulations Joshua Diaz, Science and Technology Corporation, NASA Ames Research Center February 8, 2023, 9:00 a.m. These seminars are typically held weekly, and will be recorded for on-demand playback on the web in the AMS seminar archive. Hosted by the Computational Aerosciences Branch at the NASA Advanced Supercomputing facility, this seminar series presents talks on recent achievements, innovative tools, and current problems being faced by members of the modeling and simulation community from NASA, government, industry, and academia. Alongside continually advancing the efficiency of aircraft propulsion systems, the company is also developing technologies to support greater use of cleaner, alternative fuels, including Sustainable Aviation Fuels (SAFs) and hydrogen, each of which will benefit from the increased efficiencies enabled by hybrid-electric propulsion technology.Advanced Modeling and Simulation (AMS) Seminars Raytheon Technologies is leading the development of hybrid-electric propulsion technologies across multiple demonstrator programs, including STEP-Tech and SWITCH, spanning a wide range of potential future aircraft applications. De Havilland Canada is supporting integration of the propulsion system on the experimental aircraft. Ricardo PLC is also supporting the project with component design, system integration, and testing. The development of battery component designs and associated electrical control systems will also be supported by the National Research Council of Canada and the Innovative Vehicle Institute. ![]() H55 S.A., recently the subject of a minority investment by Raytheon Technologies’ venture capital arm, RTX Ventures, will supply battery systems. Since Raytheon Technologies launched the demonstrator project via its Pratt & Whitney Canada and Collins Aerospace businesses in July 2021, supported by the Governments of Canada and Quebec, numerous organisations in Canada and around the world have joined the initiative. I am confident that 3C’s extensive flight test experience and historical relationship with Transport Canada will complement Raytheon Technologies’ outstanding team to safely demonstrate this important technological advance.” “3C has assembled a trusted Quebec team that includes Chrono Aviation, WAAS Aerospace, and Elisen & associés to integrate the hybrid-electric powertrain, battery system, and high voltage electrical harness into 3C’s Dash 8 research aircraft. “We are honoured that Raytheon Technologies has chosen our Design Approval Organization to lead the flight test program for this historic demonstrator project,” said John Maris, 3C president and chief test pilot for the project. “With our ground test program now well underway, planned flight testing will enable us to accelerate the demonstration of this next generation sustainable propulsion technology as we continue to expand our collaboration within Canada’s aerospace ecosystem and beyond.”įlight Test Centre of Excellence (Cert Center Canada – 3C), will modify and operate the De Havilland Canada Dash 8-100 aircraft, serving as the platform for future flight demonstrations. “Hybrid-electric propulsion technology offers significant potential to optimise efficiency across a range of different aircraft applications, helping our industry meet its ambitious goal for achieving net zero CO2 emissions,” said Jean Thomassin, executive director new products and services, Pratt & Whitney Canada. This powerplant technology will enable more efficient engine performance during the different phases of flight, such as take-off, climb and cruise, reducing fuel burn and CO 2 emissions by up to 30 percent compared to today’s most advanced regional turboprop aircraft. The system fully integrates a 1 MW electric motor developed by Collins Aerospace with a highly efficient Pratt & Whitney fuel-burning engine, specially adapted for hybrid-electric operation. The propulsion system’s initial run took place at Pratt & Whitney’s innovation facility in Longueuil, Quebec and performed as expected. Raytheon Technologies announced the successful first engine run of the company’s regional hybrid-electric flight demonstrator, marking a key milestone towards flight testing, targeted to begin in 2024. ![]()
