NASA's attempts to suppress the sonic boom supersonic aircraft appeared after 2025

    NASA's attempts to suppress the sonic boom: supersonic aircraft appeared after 2025 [abstract] the NASA langley research center in supersonic wind tunnel are testing noise reduction scheme, can let the supersonic airliner sonic reduce to a minimum, the supersonic flight path on the city from the interference of the sonic boom.

    Concorde supersonic airliners retired, no supersonic passenger service in the world

     According to foreign media reports, the supersonic commercial aircraft will stage a comeback, in the not too distant future, we will get faster flight experience, but the supersonic airliner is still a problem, that is the sonic boom.Supersonic airliner flight speed generally in more than 761 miles per hour, equivalent to 1225 km per hour, the sonic boom to

    personnel, building on the ground after the formation of formation damage.So NASA is developing a new technology, can let the supersonic airliner sonic reduce to a minimum, the supersonic flight path on the city from the interference of the sonic boom.

    On Concorde supersonic airliners flying routes almost no big cities, the aircraft is limited to supersonic flight over the sea, only can operate transatlantic routes, take-off and landing airport has also been restricted, so its noise level is too big.Concorde supersonic airliners after retirement, no supersonic passenger service in the world, developed by NASA is not currently supersonic airliner, and supersonic flight technology, including how to reduce the sonic boom is one of the difficulties.Supersonic aircraft in that instant, spanning the sound barrier will produce obvious shock wave, the wing leading edge will see the obvious shock wave profile.

    Scientist for NASA's langley research center, Alexandra that NASA is trying to change the limitation of supersonic airliner, because after 1973, the federal aviation administration has banned supersonic aircraft flying over in the United States.If the new certification by noise, so supersonic airliner to operate in the United States, at least from the current look, supersonic airliner can only achieve supersonic flight over the ocean.NASA langley research center, supersonic wind tunnel are testing

    noise reduction scheme, acoustics engineer Jonathan thought, we put the sonic boom "split into several parts, trying to find out which part of the disturbing noise.

    NASA laboratory also recruited volunteers, to simulate the

    supersonic airliner flight impact on passengers, if all goes well, the supersonic airliner in 2025, at least in the foreseeable future, supersonic aircraft is expected to be back on the streets, into the sequence of flights.
