Validation of FEA results by results of aero-thermal testing. Aero-Thermodynamic Loads on Lightweight Advanced Structures - ATLLAS II. D3.1.9. Final Report.

Abstract

The numerical FEA model of the “CANARD” designed from TMC material by TISICS for the aero-thermal tests using the L3K facility was considered within the frame of the ATLLAS II project. As a final specification for the CANARD model, the cooling cores with exit slit geometries providing the most efficient impingement cooling effect inside of the TMC CANARD were considered for manufacture and testing. The calculations of the temperature fields, strains and stresses in the TMC part were conducted for a 0.8 mm CANARD leading edge radius according to the heat flux density provided by DLR AS-HYP. EN3B steel was examined as a cooling core material. The results are presented, discussed and compared with the experimental data received by thermal tests using the L3K facility.
