Abstract : Results of force measurements of different deceleration devices for axisymmetric bodies with central spikes of different lengths and deflection angles, fixed spoilers (attached to the basic model at different axial stations) and conical slotted or unslotted flares at the base of the model are presented and compared. The tests were carried out in the gun tunnel of the Institute of Applied Gasdynamics at a free stream Mach number of 8.75 and a free stream Reynolds number based on the diameter of the cylindrical model part of 230 000.
