Aerospace Research: Renewal of the IROQUA Agreement

The aircraft noise reduction program, IROQUA (Initiative de Recherche pour l’Optimisation acoustiQUe Aéronautique), has been renewed for a further five years. Its objective is to reduce by half the perceived noise around airports by 2020.

Launched in 2005 by Safran, Airbus, Dassault Aviation, the CNRS and ONERA, in a network comprising some 30 laboratories, IROQUA is dedicated to research into aeroacoustics and reducing aircraft noise. This Agreement, signed under the aegis of the French Civil Aviation Authority (DGAC) and CORAC (the French civil aviation research council), was renewed on November 23 for another five years.

A reinforced initiative
To coincide with this extension, Air France and Aéroports de Paris have joined the IROQUA program alongside the original partners. The reinforcement of the network with air traffic operators and stakeholders will help drive forward the operational implementation of the technological advances arising from the research. Another new feature is the expansion of the network's areas of expertise. IROQUA will supplement its fields of investigation with new physical disciplines, such as vibroacoustics, and cognitive sciences such as psycho-acoustics. Additional lessons will be learned, to underpin the social choices facing manufacturers and decision-makers in the future.

A strategic objective for Safran
"Noise reduction is a strategic objective for Safran. When you realize that air traffic is due to double in the next 15 years [...], you can appreciate the scale of these issues for the Group, one of whose flagship products, the CFM56 (developed in partnership with General Electric), is the engine powering half of all air traffic and which equips, notably, almost three quarters of all short and long-haul aircraft," declared Marc Ventre, Executive Vice-President, CEO Aerospace Propulsion Branch, at the Agreement renewal meeting. He also pointed out the originality and the efficiency of the IROQUA approach in making a network out of scientific and technologic skills within a public / private partnership, gathering number of companies and research laboratories.
