Creation of high-speed air passenger transport is a topic that is in the focus of attention of the scientific community of the aviation industry. Scientists are concerned about finding answers to the questions posed by this ambitious task. The VIII All-Russian Youth Scientific Forum “Science of the Future – Science of the Young” with the participation of experts from leading research organisations, including the Zhukovsky Central Aerohydrodynamic Institute, became a platform for their discussion. This year’s meeting took place in Orel at the end of September, the press service of TsAGI said.
The event was attended by Viktor Kopyev, Head of the Research Centre for Aeroacoustics – Head of the Department of Aeroacoustics and Aircraft Ecology, Doctor of Physical and Mathematical Sciences. He made a report “The Problem of Supersonic Civil Aircraft (SCA) Compliance of Supersonic Civil Aircraft (SCA) with Prospective Ground Noise Standards”, in which he presented the current state of research on aeroacoustics of high-speed air transport.
“Research shows that the sources of ground noise in GHS are similar to those for subsonic aircraft, but their impact on the overall level is likely to be different. We estimate that the dominant factors will be engine jet noise, fan noise, and the airframe itself. Therefore, the solution to the problem may lie in the search for new layouts that will balance these effects,” said Viktor Kopyev.
TsAGI is currently implementing a bilateral project with the Chinese Aerodynamic Research Centre CARDC, aimed at studying aerodynamic noise and ways to reduce it for the wing of a promising supersonic civil aircraft. As part of this work, which received a grant from the Russian Science Foundation for international research, scientists are conducting tests in the institute’s acoustic chamber and the Chinese centre’s silenced wind tunnel. The results will serve to replenish the data bank on airframe noise and allow them to study the generation mechanisms of this phenomenon.
“New studies of GHS airframe noise are needed today, including large-scale work. They will make it possible to identify the main sources, develop approaches to modelling these sources and develop low-noise airframe configurations,” Viktor Kopyev stressed.
