Scientists of Perm National Research Polytechnic University have come up with a technology that allows to reduce the noise level produced by airplanes. The results of the study are published in the journal Akustika.
The developed technique is based on the lining of the aircraft engine with special structures capable of absorbing sounds. At the same time, this technology can be used not only on aircraft, but also on power plants and other units.
As Oleg Kustov, a junior researcher at the Laboratory of Noise Generation Mechanisms and Modal Analysis of the Center for Acoustic Research at Perm Polytechnic University, noted, the creation of low-noise airliners is an urgent task for aircraft manufacturers.
"Our scientific group has developed and successfully implemented a technique that will allow us to more effectively predict the acoustic characteristics of sound-absorbing linings in aircraft engines. At the same time, the processes were modeled for the first time for real structures that are used in aircraft construction," he quotes " Scientific Russia ".
At the end of September, it became known that Gazprom Neft had agreed with Aeroflot to cooperate in creating Russia's first production of aviation fuel with a minimum carbon footprint of SAF (produced on the basis of vegetable raw materials).
The partnership provides for the development of effective aviation fuel formulations in accordance with international requirements for limiting greenhouse gas emissions and the CORSIA environmental program of the International Civil Aviation Organization ICAO.
