Predictions of Rotor Broadband Noise
(Trinity College Dublin. School of Engineering. Discipline of Mechanical & Manuf. Eng, 2018)This thesis presents an enhanced method for predicting aerodynamically generated broadband noise, produced by rotating machinery. The method improves on existing work for Vertical Axis Wind Turbine (VAWT) noise prediction, ... -
Spatial Noise Source Identification of Tonal Noise in Turbomachinery Using the Coherence Function on a Modal Basis (AIAA-2011-2825)
(2011)In modern helicopter engines, the core noise generated by the combustor and turbine stages dominates the core sound radiated from the engine exhaust. Identi cation of the specific contributions of each rotor-stator stage ... -
TEENI-Turboshaft Engine Exhaust Noise Identification
(2010)The TEENI project is an FP7 level 1 (Theme 7 ? Transport) 1st Call EU-funded project. It focuses on Helicopter Engine Exhaust Broadband Noise, and tries to identify the origin of this noise from external measurements only. ...
