TEENI-Turboshaft Engine Exhaust Noise Identification

, 2010
PUBLISHED Trinity College, Foster Place, Dublin 2 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. The project was launched on 1 April 2008 and will last 3 years.
