Scientists at the Indian Institute of Science here have developed low noise technology for Rolls‐Royce aircraft engines. An 11 ‐member team led by Mr U Ramamurthy of IISc’s department of materials engineering began research in 2006 in collaboration with the UK Company and recently delivered the technology. The technology, developed using shape memory alloys, brings down engine noise during landing and take‐off. Mr Ramamurthy told STOI that silencer vanes are capable of operating at 200 degrees Celsius and higher. “Rolls‐Royce was involved in a tripartite research agreement with research groups in IISc and IIT‐Bombay as well as Imperial College, London. The objective was to discover high‐temperature shape memory alloy compositions with a new technique which could be adapted for engines,” Mr Ramamurthy said.
