HERMES Models 3036-2 and 3041 Experimentes in the HEG

Kurzfassung

Experiments on two HERMES models, 3036-2 and 3041, were performed in the HEG facility. The tests were conducted at two diaphragm burst conditions, approximately 50 and 100 MPa, with two respective enthalpies of approcimately 13 and 21 MJ/kg. Model 336-2 had an angle of incidence of 40 o and Model 3041 an angle of incidence of 30 o. Both models had their body flap and elevon deflected, 20 o for Model 3036-2 and 10 o for Model 3041. To complement these surface measurements, LIF was undertaken on Model 3036-2 and Holographic Interferometry on both models. Repeatability experiments were conducted on both models at the four test conditions, with reasonable repeatability found. Pressure and/or enthalpy effects were also investigated.
