Modern Problems of Aircraft Propulsion Aerogasdynamics Discussed at TsAGI

2 November 2021

Research on aircraft propulsion lays among top research priorities of TsAGI (a part of NRC “Zhukovsky Institute”). To discuss the topic, TsAGI organized a cross-sectoral research-and-technology conference, Modern Problems of Aircraft Propulsion Aerogasdynamics. The event took place in October.

The conference embraced a wide number of topical areas: advanced aircraft configurations, integrating engines into aircraft, aerogasdynamics of air intakes and jet nozzles, combustion processes, propellers, modern calculation methods, test facilities, and test methods. Together with TsAGI scientists, the event was attended by their colleagues from Baranov Central Institute of Aviation Motor Development, UEC-Aviadvigatel, UEC-Saturn, Motor Design Bureau, Gromov Flight Research Institute, Semenov Research Center of Chemical Physics, Federal Research Center “Computer Science and Control” of the RAS, Keldysh Institute of Applied Mathematics of the RAS, Safronov Research-and-Testing Ground for Aviation Systems, Bauman Moscow State Technical University, as well as other enterprises and institutions of the industry.

The conference opened with a plenary speech by Aleksandr Chevagin, TsAGI Deputy Head for Aircraft Aerodynamics and Flight Dynamics, Head for Propulsion Aerodynamics. His report, Conceptual Research into Technological Advance for Civil Aircraft Propulsion in 2020-2035, presented some results of exploratory and applied research by TsAGI, aimed to support the development of propulsion for modern civil aviation.

In particular, he noted TsAGI’s legacy in developing its research-and-technology basis and test facilities for solving new challenges in aviation and engine design. The speaker also showed development of the test facilities and numerical modeling methods, which significantly expanded the aerodynamics-related fundamental knowledge, enabled solving applied problems in flight safety, and increased efficiency of propulsions integrated into aircraft.

Alexander Chevagin emphasized that integrated approach to aircraft is one of the main trends in aviation industry, considering it as a part of the future air transport system as well. ‘We are currently researching and developing new technologies that will meet the current challenges in aviation, including advanced aircraft configuration, complex engine integration into airframe, methods of aerodynamic drag reduction, flow control, provision of gas-dynamic stability at limit conditions, higher efficiency achieved by decreased energy losses, lower environmental noise, etc.’ he said.

The plenary session also included a report by A.V. Lukovnikov, CIAM Head of Department, Doctor of Technical Sciences, which considered the Institute’s work aimed to provide technological advance for aircraft engines and propulsions for 2020-2030. Another report, which dealt with the use of numerical technologies for concept design of detonation propulsion, was delivered by Professor S.M. Frolov, Scientist at Semenov Research Center of Chemical Physics, Doctor of Physical and Mathematical Sciences.

Totally, the participants presented over 60 reports at the conference, including research results by industrial enterprises and research organizations.

Aerodynamics of aircraft engines lays among TsAGI’s key research activities. The scientists do a wide range of calculations and tests which enable concept design of a propulsion integrated into airframe, considering the purpose of the aircraft.
