Subsonic and Supersonic Ground Experiments for the CALLISTO VTVL Launcher Demonstrator

Abstract

CALLISTO is a technology demonstrator developed in a joint project of the DLR, CNES and JAXA in order to investigate VTVL technologies. This paper will give an update on ongoing wind tunnel tests in the Trisonic Wind Tunnel (TMK) at the DLR Department of Supersonic and Hypersonic Flow Technologies in Cologne for the current flight configuration. Focus is the evaluation of flow visualization techniques like schlieren imaging and oil film visualization and comparison of the experimental data with the AEDB. Flow conditions were chosen for representative flight Mach numbers of the subsonic up to supersonic flight regime; different angles of attack and the ascent as well as descent configuration were investigated. Furthermore the already presented experimental results [3] will be updated and extended by the roll moment measurements. Finally an outlook on planed experimental investigations will be given.
