Optimization of air jet pump design for acoustic application (OPA)
Date du début: 1 avr. 2013, Date de fin: 31 juil. 2015,
"According to the call topic, the goal of the project is to optimize the design of a subsonic jet pump, to reduce as much as possible the noise level. The optimization of the subsonic jet pump will be done from the aerodynamic point of view and two type of analyses will be used, a RANS analysis as a “fast-screening” procedure to be able to identify using such techniques a trend in the flow behavio ...

OPtimisation for low Environmental Noise impact AIRcraft (OPENAIR)
Date du début: 1 avr. 2009, Date de fin: 30 sept. 2014,
Reducing noise from aircraft operations perceived by airport neighbouring communities is a major challenge facing the aircraft manufacturing industry, social society and the air transport business. By adopting a whole aircraft approach based on the latest developments in active / adaptive technologies, flow control techniques and advances in computational aero-acoustics applied to the major causes ...

Turboshaft Engine Exhaust Noise Identification (TEENI)
Date du début: 1 avr. 2008, Date de fin: 31 mars 2013,
"Helicopters can generate a large amount of external noise, as their traditional missions –rescue, medical, law enforcement– are very close to populated areas. As emphasised in ACARE SRA2, increasing rotorcraft missions in the public vicinity should not lead to increasing public disturbance. Turboshaft engine is known as a major contributor to exterior noise for take-off conditions. ACARE SRA2 ob ...
