| الوصف: | International audience ; The performance of two different PSP used at DLR and ONERA is compared by carrying out bench mark testing using the oft-studied configuration of an oscillating shock wave (up to 100 Hz) on a bump in the Mach 1.4 flow of the ONERA S8Ch wind tunnel. The shock is made to oscillate by rotating a cam with elliptical cross section, placed at a further downstream position, at frequencies of 15, 30 and 50 Hz. Both paint types are well known and much has been published on their use: the ONERA PSP is a Ruthenium complex Ru(dpp) 3 Cl 2 placed as a thin layer on an anodized aluminum substrate, while the DLR PSP is a Platinum complex PtTFPP on a base coating containing TiO 2 particles. S8 run conditions were held constant, and separate test run series were carried out with each paint. Instationary calibration was also carried out using a special test rig. Fourier analyses of the PSP results in S8 enabled a semi-quantitative comparison of the time response of both paints. This is the first published attempt (to the authors' knowledge) of carrying out a side-by-side comparison of the characteristics of these two paints on such a flow configuration in a wind tunnel. Particular emphasis is placed on their handling properties and, above all, their time responses. ; La performance de deux PSP différentes, utilisées au DLR et à l'ONERA, est comparée lors d'un essai sur une configuration connue d'oscillation d'onde de choc sur une bosse testée à Mach=1.4 dans la soufflerie S8Ch. L'oscillation forcée du choc est obtenue au moyen d'une came elliptique en rotation placée en aval de la veine d'essai, à des fréquences de 15, 30 et 5Hz.Les deux PSP testées ont déjà par ailleurs fait l'objet de plusieurs essais en soufflerie. La PSP Onera utilise un complexe de Ruthénium Ru(dpp)3Cl2 adsorbé sur une surface d'aluminium anodisé. la PSP DLR contient un complexe de Platine PtTFPP incorporé dans un liant poreux contenant des particules de TiO2. Les deux peintures sont testées séparément sur la même configuration ... |
