Combustion regimes in aircraft engines discussed at TsAGI
10 April 2018
In early April 2018 the Zhukovsky Central AeroHydrodynamic Institute (TsAGI) hosted a workshop, devoted to the work of the scientific laboratory “Research and Development of Physical Models and Numerical Technologies for Describing Combustion Regimes in Aircraft Engines.” Scientists from TsAGI, Moscow State University, and the laboratory leadership took part in the event.
The workshop’s main task was to prepare and hold hot-tests at TsAGI’s hypersonic simulator. Institute specialists’ immediate plans are to build a high-speed combustor chamber with optical windows. The experiment is planned for this autumn. As a result, the scientists are planning to set up an experimental data system to validate theoretical models and calculation programs.
“The hot-test is the project objective,” explained Vladimir Vlasenko, Deputy Head of the Laboratory and Doctor of Physics and Mathematics. “Optical windows will allow us to view in detail turbulent combustion inside the combustion chamber. It is especially important to ensure the accuracy of the experiment. We have to prevent vibration, chamber deformation and other negative effects. I believe we will be able to pin point the area where combustion begins. This will be the first-of-its-kind experiment for TsAGI.”
In addition, participants discussed test calculations of turbulent flows, which were conducted in the laboratory. They also discussed the development of promising jet engines with resonator and rotating detonation. The controlled detonation would significantly increase the efficiency of the engine. The laboratory performance targets became the final issue of the event.
The laboratory “Research and Development of Physical Models and Numerical Technologies for Describing Combustion Regimes in Aircraft Engines” was opened at TsAGI’s Technopark in July, 2017. Creation of the laboratory became possible thanks to the mega-grant of the Government of the Russian Federation, won by TsAGI in 2016. Professor Vladimir Sabelnikov, adviser to the French national aerospace research center ONERA became the head of the laboratory. The project will last for 2 years.
