Flow Field Calculations for HERMES HMSV3 Configuration at Supersonic Speed Using the DLR Euler Code.

Kurzfassung

The present report describes the work at DLR for the technical assistance contract between CNES and DLR from January 1989 to January 1990. The first part covers the extension of the Euler code for the calculation of air in equilibrium. In the second part, the grid generation and the aerodynamic calculations for the HERMES HMSV3 configuration are outlined. Calculations are carried out with and without a deflected rudder of the vertical tail. The predicted flow fields for the varying onflow conditions are discussed. It is shown that theoretical coefficients of lift, pitching moment and drag as well as the derivatives of side force and roll and yaw moment are in good agreement with experimental data. The numerical solutions can be used to assess the vertical tail efficiency.
