The Cambridge-MIT Institute says:

Cambridge-MIT Institute 'Silent' Aircraft Initiative.

This long-term, transatlantic initiative brings together leading academics from Cambridge University in the UK and the Massachusetts Institute of Technology (MIT) inthe United States with representatives from all parts of the civil aerospace/aviation industry. They are working together, sharing knowledge, testing the technologies and developing the design for a plane that is radically quieter than current passenger aircraft.

CMI's 'Silent' Aircraft Initiative has an ambitious aim: to discover ways dramatically to reduce aircraft noise, to the point where it would be virtually unnoticeable to people outside the airport perimeter in a typical built-up area. Not only will this directly advantage communities situated close to airports, it will also provide a major boost to the UK aerospace industry, and help UK airlines and airports to operate more productively.

London Luton Airport is the latest in an extended "Knowledge Integration Community" of partners involved in this three-year project, including regulators, airport operators, airlines, aerospace manufactures and representatives of community groups opposed to aircraft noise. Fellow partners in the project include British Airways, Boeing, the Civil Aviation Authority, Cranfield University, Marshalls Aerospace, National Air Traffic Services, and Rolls-Royce.

London Luton Airport has made a long-term commitment to the initiative, and an Airport team led by Airfield Environment Manager Neil Thompson will be assisting the CMI team in a variety of practical ways, allowing data acquistion vital for the development of the next generations of low noise emission passenger aircraft.

To meet their targets the Cambridge-MIT Institute (CMI) 'Silent' Aircraft team are currently looking at a number of radical concepts for reducing aircraft noise - including embedding jet engines within the main fuselage, new undercarriage and airframe configurations, and a complete re-examination of the conventional wisdom on take-off and landing approaches.

If you forgive the dreadful politically correct jargon ("Knowledge Integration Community") then anything along this line is welcome. These are the real environmentalists, people who do science and engineering research to make the situation better. (As distinct from the self-proclaimed environmentalists who only know how to complain about the "sins" of the world.)
