Abstract
The base bleed of a two-dimensional body with different slot widths at the trailing edge is examined. It is shown that the value of the maximum base pressure depends on the slot width but in all cases corresponds to the same value of the momentum flux density. This parameter is determined only by the body drag. Turbulent characteristics of the wake behind the body are measured at the optimum value of the momentum flux density. Visualization of the flowpattern immediately behind the trailing edge of the body was made without and with bleeding.
