Objective
In the domain of civilian aeronautics, the increasing noise restrictions around airports are a challenging problem for aircraft and engine manufacturers. Despite significant progresses since the definition of ACARE objectives, jet noise remains the main source of noise for an aircraft at take-off and many works have been dedicated to its understanding and its reduction. First generation of noise reduction devices were passive such as chevrons or mixer which enhance the mixing in the shear layers to reduce jet noise, but also decrease the engine performance during cruise. Second generation noise reduction concepts under development are active and can be switched off after take-off.
ORINOCO is a small focussed collaborative project based on the cooperation between Europe and Russia and deals with advanced engine noise control based on plasma actuators. Plasma technologies have initially been developed for flow control and their first applications for jet noise reduction were confronted with technical aspects far from acoustics. This use of plasma actuators is a novel concept that requires fundamental approaches to understand the interaction mechanisms with the main jet and the resulting radiated sound. The main topic of ORINOCO is manifold and contains theoretical, numerical and experimental investigations for an efficient implementation of plasma actuators for jet noise reduction, especially on the basis of instability waves reduction. As a consequence of these fundamental considerations, most of the 13 partners involved in ORINOCO (7 European - 6 Russian) come from Academic or Research community. Several plasma actuators concepts will be studied and assessed in small scale anechoic facilities with isothermal main jet and the most promising ones will be evaluated with a heated main jet. The work performed within the project will be monitored by an Expert Panel composed by industrial members from Europe and Russia, proof of their interest on this topic.
