Second ENODISE Public Workshop
Advanced porous treatment, liners and meta-materials for engine and air frame noise mitigation
RWTH Aachen University, Germany
with the participation of DJINN and INVENTOR
ENODISE (Innovative Design of Installed Aircraft Components for aircraft noise reduction), coordinated by VKI, is aimed at reducing aircraft noise and gaseous-polluting emissions through novel aircraft architectures. These feature a much tighter integration of the propulsion system with the airframe than in conventional aircraft. Complex aerodynamic and acoustic engine-airframe interactions result, which must be better understood to achieve the envisaged benefits. ENODISE investigates the key aeroacoustic installation effects at low TRL level, and provides a solid background of knowledge and methods, based on simplified but typical configurations, allowing several integration solutions to be evaluated.
INVENTOR (Enabling Optimized Disruptive Airframe-Propulsion Integration Concepts), coordinated by ONERA, is studying the physics of noise generated by landing gears and high-lift devices at landing/approach with a view to developing innovative low-noise installed landing gear, high-lift device components and noise reduction technologies to lower external noise from business jets and short-to-medium range transport aircraft.
