Abstract

HEG, a new high enthalpy shock tunnel has recently been inaugurated at DLR in Goettingen. Its prinicipal function within the aerodynamic strategy of the HERMES space vehicle project is to examine the influence of non-equilibrium gas dynamics on the external aerodynamics and heat fluxes of the vehicle in the range where heat loaads are highest. The facility layout of this free piston shock tunnel consists of three main sections, the driver section, the shocktube and the test section including a contoured nozzle. The main features of this arrangement are described along with a presentation of its main operaing characteristics. A description of the tunnel instrumentation focuses on the LIF system which is beeing developed and validated for use in HEG. Some validation results are presented. Finally the facility calibration procedure is described and first results are presented.
