DLR AS-HYP Transition Experiments on Bolt-Model in H2K

Abstract

Within this report the experiments performed with the BOLT geometry in H2K at DLR are described. The acquired data are analysed in detail. Still to be done is the mapping of the IR data onto 3D surfaces and the computation of heat fluxes from the measured surface temperatures. Nevertheless the influence of Mach number, Reynolds number, angle of attack and yaw angle could be documented. Several interesting features including evidence for second (Mach) modes could be detected. It is planned to publish the findings in a journal paper.
