NASA, ONERA team up on noise research

On the occasion of the International Forum for Aviation Research IFAR, held in Daejeon (South Korea), Bruno Sainjon, CEO of the French aerospace research agency ONERA, and Dr Jaiwon Shin, Associate Administrator for the Aeronautics Research Mission Directorate at NASA, signed an agreement specifying the terms of an enhanced bilateral scientific cooperation for 4 years on the subject of reducing aircraft noise.

This agreement covers four main research topics:

  • Acoustic liners (absorbent materials)
  • Noise modeling around an airport platform (modeling of its source and of its propagation)
  • Perception and noise discomfort perceived by residents (auralization and psychoacoustics)
  • Signal processing methods for the identification of sound sources (spatial location, sound levels)

The DLR will also participate in the topic of modeling the noise around an airport platform and will also contribute flight data from its test aircraft Attas (a Fokker VFW614).

The purpose of the agreement is the mutual comparison of various noise prediction methods, thereby acquiring new knowledge on the same field of research but through different methods, with which both institutions will be able to increase their expertise.

The agreement will strengthen the NASA-ONERA partnership on noise initiated in 2008, and is part of the framework agreement for cooperation signed between the two institutions in 1991.

The first ONERA-NASA collaboration took place more than 40 years ago. In 1972, it related to helicopter aeroelasticity, and research topics have since diversified to cover materials and structures, aerodynamics, human factors, icing, air traffic management (ATM) and aircraft noise reduction.
