Titel:
A Contribution to Noise Improvements for Aircraft by Noise Measurement Evaluation
Autor(en):
F. Weiblen
Zusammenfassung:
Based on noise measurement evaluation of various propeller driven aircraft according to ICAO Annex 16 standards, Chapter VI (flyover noise) and Chapter X (take-off noise), constraints for the design of modern low-noise propellers are discussed: Reduction of propeller speed and propeller diameter are the most valuable parameters to be changed. Both is used in the demanding field of changeing propeller installations on existing aircraft in order to satisfy newest noise allowables. This is obtainable with advanced variable pitch propellers using rounded blade-tips and high lift profiles in the outer blade portions.
