Current engine noise and reduction technology
Autor: Eric Nesbitt
Publikováno v: CEAS Aeronautical Journal. 10:93-100
This article reviews current turbofan engine noise and engine noise reduction technology, specifically focusing on the engine technology of larger passenger jetliners which have entered into service within the last ten (10) years. Important factors i

Acoustic Phased Array Quantification of Quiet Technology Demonstrator 3 Advanced Inlet Liner Noise Component
Autor: Leon Brusniak, Jackie W. Wong, Eric Nesbitt, Douglas M. Nark, Michael G. Jones
Publikováno v: 25th AIAA/CEAS Aeroacoustics Conference.
Acoustic phased array flyover noise measurements were acquired as part of the Boeing 737 MAX-7 NASA Advanced Inlet Liner segment of the Quiet Technology Demonstrator 3 (QTD3) flight test program. This paper reports on the processes used for separatin

Flight Test Methodology for NASA Advanced Inlet Liner on 737MAX-7 Test Bed (Quiet Technology Demonstrator 3)
Autor: Jackie W. Wong, Eric Nesbitt, Douglas M. Nark, Michael G. Jones
Publikováno v: 25th AIAA/CEAS Aeroacoustics Conference.
This paper describes the acoustic flight test results of an advanced nacelle inlet acoustic liner concept designed by NASA Langley, in a campaign called Quiet Technology Demonstrator 3 (QTD3). NASA has been developing multiple acoustic liner concepts

Towards a Quieter Low Pressure Turbine: Design Characteristics and Prediction Needs
Autor: Eric Nesbitt
Publikováno v: International Journal of Aeroacoustics. 10:1-15
This article examines Low Pressure Turbine (LPT) noise in modern aircraft and shows how difficult it is to design a quiet LPT. LPT noise has long been neglected in terms of research and prediction capability due to it being considered of lesser impor

Forward Flight Effects on Chevron Noise Reduction
Autor: Eric Nesbitt, Russell Young
Publikováno v: 14th AIAA/CEAS Aeroacoustics Conference (29th AIAA Aeroacoustics Conference).
Jet engine exhaust nozzle chevron designs are used for reducing low frequency jet noise by enhancing the jet mixing process. The development of an empirical method to predict the effect of chevrons, based on a static engine test, can eliminate the ne
