Raytheon explores pioneering power systems for future aircraft
The company’s involvement spans the full range of power architecture and product collaborative initiatives under the Aerospace Growth Partnership which include: Power Off-take and Power Conversion for the More Electric Engine (SILOET II, Rolls-Royce), Electric Engine Start power delivery (POMOVAL, Labinal Power Systems), Motor Drive power delivery sub-systems (LAMPS, UTC), Dedicated HiTSiC Power Modules (R-PSM, Raytheon), and the Harsh Environment Health Monitoring Devices (HEEDS, AEC).
Central to Raytheon’s strategy is leveraging its unique HiTSiC (High Temperature Silicon Carbide) produced at its UK foundry, which excels at optimal power delivery in high density, high temperature power supplies. Existing modules have a maximum operating temperature of around 150°C due to the limitations of silicon devices. As a result, large, heavy liquid cooling systems are required. Raytheon’s new silicon carbide can operate at temperatures of above 300°C, allowing more compact modules and greater efficiency, which is perfect for commercial aircraft, breaking away from the traditional tradeoffs while providing great value for money.
Steven Doran, Managing Director of Power and Control, Raytheon UK, commented: “Raytheon has a 25 year track record in electronic systems for harsh operating conditions where high current, power density, temperature and value are the key factors. The SWAP-V (Size, Weight, Power – Value) goal is being achieved through greater collaboration, with industry and academic experts in emerging technologies for harsh environments.”
