Boeing and Lockheed Martin under contracts from the NASA N 3 Supersonic Program have tested what they call SUGAR (Subsonic Ultra Green Aircraft Research) Ray concepts using a Hybrid Wing Body to achieve a 37 dB reduction in Noise relative to today's aircraft. But it still falls short of NASA's goal. Concepts for 2030 to 2035 time frame are being tested. It includes a low sonic boom concept with a V-tail (ni-titanium)to shield NOISE and control the Sonic Boom. They aver that it is possible to achieve Community Noise Certification Limits as subsonic aircraft, say 65 to 75 dB limits. That will also make the aircraft to operate at maximum cruise speed even over land. Others working on such aspects include GE Aviation; Massachusettes Institute of Technology; and Northrop Grumman.

Raja, your contribution is worth acclaim! May there be plenty of them, so that the country's unknown potential brains will lead us to a meaningful conclusion!

Knowing is a great think indeed, something most of don't have. But a thousand times better is conceptualizing and putting knowledge into practice. That's where the real test lies. Hope all knowledge everywhere is converted into practical reality.
