After a brief description of the Propulsion Test Centre in terms of capacity and test types, the reasons which led the CEPr (Centre d'Essais de Propulseurs) to set up its digital simulation activities are set out. The objectives given to these activities were then abandoned. Digital simulation is used in numerous test projects and supports moves to renovate the installations such as forecasting ideas on the subject. The calculating code used is FLUENT which is hoped to validate applications belonging to the CEPr. Four examples are presented hereafter, concerning a renovation project of the upper part of the R3 and R4 test bank, a UAV test in a supersonic free jet flight for Mach and lower altitudes as well as a method for developing distortion grids. Finally, the activity's development perspectives are presented from a technical angle.
