Supersonic - the world is still looking for a successor to the Concorde, but sonic boom and overflight noise remain the tallest hurdle. Both Lockheed Martin and Boeing are working with NASA exploring concepts which enable dramatically reduced noise levels, making a modern supersonic jetliner a possibility.
Since the Concorde’s final landing at London’s Heathrow Airport nearly a decade ago, commercial supersonic air travel has been as elusive as a piece of lost luggage. However, this hasn’t stopped NASA from continuing the quest […]
"There are three barriers particular to civil supersonic flight; sonic boom, high altitude emissions and airport noise. Of the three, boom is the most significant problem,” said Peter Coen, manager of NASA’s High Speed Project with the agency’s Aeronautics Research Mission Directorate’s Fundamental Aeronautics Program.Previous research by NASA, the military and the aircraft industry has determined that a variety of factors, from the shape and position of aircraft components to the propulsion system’s characteristics, determine the make-up of a supersonic aircraft’s sonic boom. Therefore, engineers are able to tune or “shape” a boom signature through design to minimize the loudness of the boom it produces in flight.
