TsAGI and CIRA Specialists Start a Joint Aerodynamic Noise Reduction Project
In March 2014 in Capua (Italy) a meeting was held between the specialists from the Central Aerohydrodynamic Institute named after Prof. N.E. Zhukovsky (TsAGI) and the Italian Aerospace Research Center (CIRA) dedicated to the launch of the NRD project (Noise Reduction Devices) as a part of the European program Clean Sky.
In accordance with the implementation plans for this project, specialists from Russian and Italian aviation science centers will conduct research aimed at reducing the noise of wings flaps of long-haul aircrafts. It is assumed to employ innovative technologies based, inter alia, on influence on the vortices formed near the side edges of the flaps. TsAGI scientists will focus their activities on active and similar passive noise control methods for the Russian future long-haul aircraft, and CIRA specialists will focus efforts on passive noise control techniques within the framework of the program for creation of a Green regional aircraft.
Head of Aircraft Aeroacoustics and Ecology Department TsAGI Viktor Kopyev noted that; “Such studies have not been conducted in Russia to date. Results should provide a basis for the development of further cooperation between national and European research centers within the Clean Sky and Clean Sky-2 programs.”
Reducing the noise generated by the airframe on the ground is one of the key areas of the Clean Sky program. Noise requirements recommended by International Civil Aviation Organization (ICAO) become more stringent, so in creation of new aircrafts it is necessary to develop new approaches to the reduction of aerodynamic noise, including noise generated by the flow around high-lift devices. The joint project of TsAGI and CIRA, uniting research potential of Russian and Italian scientists, is aimed at solving this problem.
Clean Sky is one of the largest aeronautical research programs in Europe, whose aim is to improve the environmental performance of air transport. The project implementation period is
CIRA is a company founded in 1984 in Italy to manage the national aerospace research program. The main objectives of the Italian aerospace center are the acquisition and transfer of new technologies aimed at improving the competitiveness of existing companies in the industry and encouraging the creation of new companies, as well as promoting education and awareness of aerospace specialists. To achieve these goals CIRA develops research projects, domestic and international cooperation and outreach activities to spread the knowledge and technologies.
