TsAGI scientists report ASPIRE project results

2 April 2018

ASPIRE is an aerodynamic and acoustic capability development project for high bypass ratio engines in which TsAGI is involved. Scientists of the Russian Center for aeronautical science, together with colleagues from ONERA (France), DLR (Germany) and NLR (Netherlands) discussed the project’s progress and outlined further plans at a meeting in Brussels (Belgium) in March.

TsAGI is tasked with a number of ASPIRE projects. Scientists develop tools for measuring the sound-absorbing features of lining materials and create noise interdiction technologies for engines and wing jets. They also focus on the sound in flow propagation and install microphones on streamlined surfaces of the aircraft.

“The TsAGI team has a unique opportunity to participate in debugging native measuring liner acoustic techniques,” noted Ivan Belyaev, TsAGI Senior Research Scientist of the Department of Aeroacoustics and ecology aircraft. “We will be able to compare our results with the ONERA and DLR data; they have been running similar developments for some time. In addition, for the first time in world practice, we have measured a number of engine and wing jet acoustic interdiction characteristics. The results confirm the high level of TsAGI’s experimental research. In the future we will be able to significantly improve the simulation of the acoustic source and to develop new reduction methods.”

ASPIRE (Aerodynamic and acouStic for high-by-Pass ratIo tuRbofan integration) is the project under the authority of Clean Sky 2 of the EU Framework program “Horizon 2020.” The work began in January 2016 and will end in September 2018.
