BAE Systems’ FAST Labs™ research and development organisation has been awarded a $12m contract by the US Defense Advanced Research Projects Agency’s (DARPA) High Operational Temperature Sensors (HOTS) programme.
Many critical defense and industrial systems such as hypersonic aircraft and missiles, automotive, jet engine turbine, and oil-and-gas systems that operate in extreme temperature conditions. Current sensors have limited performance as they cannot operate in temperatures higher than 225°C. Their capability is limited by the materials that comprise the sensors themselves, the accompanying circuitry (e.g., silicon-based transistor technology) and packaging.
The HOTS programme will help develop microelectronic sensor technologies capable of high-bandwidth, high-dynamic-range sensing at extreme temperatures.
“Due to advances in materials and processes, there is now an ability to pursue high-bandwidth pressure sensors capable of performing in high-temperature environments not previously possible,” said Amrita Masurkar, technology development manager at BAE Systems’ FAST Labs™ research and development organisation. “Through the HOTS programme, applications such as industrial process control, jet engine prognostics, and space exploration could benefit from collection of real-time data using high-temperature pressure sensors and circuitry.”
Under the terms of the contract, BAE Systems will design and build a new pressure sensor module – consisting of an integrated transducer and signal-conditioning microelectronics – able to operate with high performance at 800°C or 1,472°F.
Work on this programme will take place at BAE Systems’ facilities in Nashua, New Hampshire and Merrimack, New Hampshire. It will also include collaboration with subcontractors The Penn State Applied Research Laboratory, Purdue University and Kampanics, LLC, and supplier GE Aerospace’s research centre.
