Aeroacoustic Noise Source Identification Using Irregularly Sampled LDV Measurements Coupled with Beamforming (AIAA-2011-2719)
(2011)This paper develops a technique which relates dynamic pressure measurements taken outside the hydrodynamic eld of a low speed jet to single point, one component velocity measurements taken within the jet using a Laser ... -
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. ...
