The Aeroacoustic Source Mechanisms of Subsonic-tip-speed Propellers

Dobrzynski, W. (1998) The Aeroacoustic Source Mechanisms of Subsonic-tip-speed Propellers. Invited Lecture, Haifa (isr), 31.08.1998.

Full text not available from this repository.


This basic lecture on propeller noise summarizes the fundamental noise generating mechanisms for subsonic tip speed propellers. Based on that the effects on noise of different geometrical and operational parameters are presented. Realistic propeller installations often cause excessive noise to be generated. This may be due to oblique or disturbed inflow conditions and non-uniform rotational speed. Related noise characteristics and governing parameters are discussed. Flyover noise measurement and -analysis techniques are described and examples of typical test results are provided.
