Ways of Reducing Noise of a Ducted Fan Aircraft Propulsion Unit

Original language description

The UL-39 ultra-light aircraft which is being developed by the Institute of Aerospace Engineering, Faculty of Mechanical Engineering, CTU in Prague, is equipped with an unconventional ducted fan propulson unit. This paper deals with noise sources of thispropulsion unit and ways of reducing its noise level. The main sources of noise are identified and discussed. Then, for each respective source, methods of computational estimation of acoustic quantities along with potential noise-suppressing design improvements are presented
