Experimental investigation of rotor/stator interaction noise generation, acoustic mode measurements

Zandbergen, T. (author)

An experimental investigation was carried out in the low speed wind tunnel LST to study aircraft engine noise generation by rotor/stator interaction. Reported is a follow-up experiment including detailed acoustic measurements in the duct downstream of a rotor with cylindrical pins to complement earlier tests whereby rotor wake velocities and...

Experimental investigation of rotor/stator interaction noise generation. Model description and aerodynamic measurements

Zandbergen, T. (author)

An experimental investigation was carried out to study aircraft engine noise generation by rotor/stator interaction. The experiment was designed to enable a first step verification of a theoretical fan noise model and to indicate further developments which may be needed to provide a representative acoustic field modelling for engine duct liner...

Propeller noise measurements inf DNW on the fuselage of a twin engine aircraft model

Zandbergen, T. (author), Sarin, S.L. (author), Donnelly, R.P. (author)

Results of sound pressure measurements on the fuselage wall of a twin engine propeller driven model are presented. The tests were carried out in the German-Dutch low speed wind tunnel DNW in the Netherlands. The model was equipped with either metallic propeller blades or composite blades. The propeller diameter was 0.762 m. Six microphones were...

In-flight acoustic measurements in the engine intake of a Fokker F28 aircraft

Zandbergen, T. (author), Sarin, S.L. (author), Laan, J.N. (author), Zeemans, H.J. (author)

Acoustic measurements were carried out in the engine intake ducts of a Fokker F28 aircraft during flight. One of the two tail-mounted, low by-pass ratio engines having a hard-walled intake was instrumented to determine the amplitudes of the circumferential modes which constitute the sound field. In the other engine the impedance of the inlet...

On the practical use of a three-microphone technique for in-situ acoustic impedance measurements on double layer flow duct liners

Zandbergen, T. (author)

A three-microphone technique is presented for in-situ acoustic impedance measurements on double layer liners of the Helmholtz resonator type. It can be used under conditions of flow and arbitrary noise sources. The emphasis of this paper is the practical application of this technique, including microphone installation and the implications of...

The NLR/NGTE joint programme on the measurement of attenuation and impedance in acoustic flow duct facilities.

Zandbergen, T. (author), Martlew, D.L. (author)

The National Aerospace Laboratory NLR in the Netherlands and the National Gas Turbine Establishment NOTE operate similar acoustic flow duct facilities but with differences in their respective approaches to the measurement of attenuation and impedance of duct linings. A joint exercise was arranged with the object of comparing methods and results,...
