First reporting meeting of the DeSiReH project held in Germany
Professionals of TsAGI took part in the first reporting meeting within the DeSiReH 7FP EC (Design, Simulation and Flight Reynolds Number Testing for Advanced High Lift Solutions) project. In
The project partners DLR (Germany), FOI (Sweden),
As a test pattern, experimental data was used which was obtained within the previous
The study proved that none of the currently existing RANS methods gives the correct description of the fluid physical peculiarities under
Special interest was paid to a discussion on optimization techniques. The representatives of Dassault Aviation (France) and CIRA (Italy) demonstrated that using the Adjoint approach makes it possible to apply, in optimizing cycles,
DLR proposed to consider the numerical scheme entropic error influence upon the results when computing the aircraft drag coefficient. In a number of cases the abovementioned influence reaches 20% and requires particular attention as the entropic function is used as a restricting parameter during optimization (it is not to grow). The ONERA representatives touched upon the heat issue. For the second time they demanded control over the accuracy of obtaining the wing integral characteristics not only for the surface but for the shape as well. It is a rather severe test on conservatism of applied numerical schemes.
A celebration in honor of one of project partners took place after the seminar finalized its work: The IBK Company observed its 25th anniversary. Compliments and a souvenir were presented on behalf of Sergey Chernyshev, Executive Director of FSUE TsAGI.
«We note the heightened interest that was manifested to TsAGI on behalf of both the seminar participants and of the official establishment," said Sergei Bosnyakov, Deputy Head of propulsion aerodynamics department, the DeSiReH project Leader on behalf of TsAGI. «All this confirms the high regard for TsAGI in the 'European table of ranks'.»
