The paper deals with the comparison of computations made at DLR and ISL on the interaction between a lateral jet issuing from a generic missile body and the oncoming supersonic cross-flow. Steady-state numerical simulations are carried out by 3D, viscous, turbulent, Reynolds-Averaged Navier-Stokes Codes; at DLR, a hybrid mesh is used for the TAU calculation, whereas at ISL a hexahedral mesh is used for the CFX computation. Experimental data acquired in the DLR wind tunnel TMK in Cologne act as references for the computations. Caiculations are made for a cross-flow Mach number of 2.8, for angles of attack of -5, 0 and 10 degrees and for a jet ejection pressure ratio of 100. The test model is a cone-cylinder-flare body with a side-jet nozzle located in the cylindrical part, representing a simple generic high-speed missile configuration. Surface pressure measurements were carried out in Order to validate the corresponding computations. The agreement between the computations and the experiments in terms of pressure distribution is obtained with a high degree of accuracy by the codes, in spite of some small discrepancies.
