AEROTHERMODYNAMICS OF A WINGED REENTRY VEHICLE IN HYPERSONIC FLOW

摘要

The aerothermodynamics of the EOS-configuration of the Aachen collaborative research center 253 "Fundamentals of Design of Aerospace Planes" is investigated. Heat flux and pressure distributions are measured as well as aerodynamic loads. Strong interferences and non-linearities between loads and signals caused by the rigid design of the internal strain gage balance are corrected by an interference correction. To minimize low-frequency oscillations during the test time, a light weight carbon fibre model is used. Acceleration induced signals caused e. g. by model support oscillations are compensated. Stage separation, ascent phase and reentry are simulated in the shock tunnel TH2. For the stage separation tests the lower stage fuselage is simulated by a flat plate aligned with the test flow. Reentry simulations at high angles of attack are performed for high and low stagnation enthalpies to evaluate real gas effects on the aerodynamic loads.
