About some directions in development avation engine buildings

Abstract


Analysis of the acoustic characteristics of the engines with open rotor and turbofan engines shown what in engine noise with open rotor in addition to traditional component of the noise added tonal noise peaks at combination frequencies in low frequency part spectra. All of this creates many difficulties in the reduction the noise of aircrafts with this engines on the ground. Problem of choise engines for future aviation discussed.
