  • Method for reducing jet exhaust takeoff noise from a turbofan engine
    Patent number: 3987621
    Abstract: In a turbofan engine for jet aircraft the inner stream includes no noise suppression apparatus and the jet exhaust noise generated at takeoff is reduced by mechanically suppressing the jet exhaust noise of the outer stream and operating the engine at a bypass ratio, fan pressure ratio and gas generator power setting which yield a jet exhaust noise level from the suppressed outer stream which is louder than the jet exhaust noise level from the unsuppressed inner stream.
