Workshop ORINOCO on jet noise reduction with plasma actuators

Wednesday 25th September 2013 - Onera Châtillon (Salle Contensou)

 

The participation is free of charge, but registration is required.

Logo OrinocoIncreasing noise restrictions around civilian airports continue to offer a challenging problem for aircraft and engine manufacturers. Research and development efforts over many years have resulted in significant reductions in the noise radiated by aircraft engines currently in service. Despite these progresses, jet noise still remains the main source of noise at takeoff.  To reach the targets of the ACARE agenda (a reduction of the external noise by 10 EPNdB per operation of fixed-wing aircraft by 2020) a technology breakthrough is now necessary.

ORINOCO embodies the cooperation between Europe and Russia in the framework of advanced engine noise control based on plasma actuators. The novel concept of using plasma actuators controlling jet noise requires a fundamental approach to understanding the interaction mechanisms with the main jet and the resulting radiated sound. Several avenues of investigation - theoretical, numerical and experimental – are pursued towards the evaluation of new plasma actuators concepts for jet noise reduction.

The present workshop will provide the opportunity to present the main results obtained in ORINOCO. During the four years of the project, some actuators were developed and improved for the specific objective of jet noise reduction. The instability wave concept was at the centre of theoretical investigations to analyse the mechanisms of noise radiation. Finally, control strategies were studied through stability analysis in order to define the best way to act on the jet.
