Creating contemporary aircraft includes the efforts to minimize its environmental footprint. Reducing aircraft noise is one of the top challenges. Solving it is an activity area of TsAGI (a part of NRC “Zhukovsky Institute”). Relevant results of such activities were presented at the Environmental Acoustics 9th Russian National Conference of Young Scientists and Specialists, hosted by Bauman MSTU from May 23 to 24.

The Conference was opened with a lecture by D. Sc. Viktor Kopyev, Head for Aircraft Aeroacoustics and Ecology, TsAGI. He spoke on the research aimed to reduce aircraft noise, both environmental and cabin.

‘It is essential to understand clearly the nature of sound generation to reduce aircraft environmental noise and to provide acoustic comfort for the passengers and the crew. The tests done with TsAGI’s unique facilities allow eliminating undesirable acoustic effects timely, at the design stage. During the tests, we measure the level of noise and can localize its exact sources, which are mostly aircraft propulsion, including open rotor and propellers, the streamlined airframe units, interference noise, etc.’, said Viktor Kopyev.

Aimed to show and discuss the new-generation specialists’ scientific achievements in aeroacoustics, the Conference showed the results of the research by young scientists and postgraduates from TsAGI (M. Demyanov and V. Bashkatov), and by future MIPT graduates who are currently practicing at TsAGI (A. Brazhkin, I. Mironyuk, and A. Petrov). Their reports highlighted cutting-edge scientific approaches to noise—for instance, the study of capacities of liners in creating green aircraft. The main solution is the acoustic lining of engine ducts and optimization of lining capacities to reduce propulsion noise. TsAGI also presented its achievements in jet stream numerical modeling, research into contribution by single propeller and open rotor into aircraft noise, issues of multi-array microphone acoustic measurements, etc.

The 9th Russian National Conference of Young Scientists and Specialists was timed to 110th birthday anniversary of Yevgeniy Yudin, the aeroacoustics scientist and the father of aeroacoustics in TsAGI. He contributed largely to the development of approaches aimed to solve aircraft environmental noise issues, to give recommendations on jet aerodrome noise suppressors, etc.
