Book excerpt: Base bleed is a technique whereby all or part of the boundary layer is 'bled' from the rear portion of a projectile to the base region. Passage from the model's surface to the base region is by means of concentric cylindrical passageways. The purpose of base bleed is to reduce the Magnus moment on overlong spinning bodies of revolution and to reduce the base drag. Both analytic and experimental results are presented. The boundary layer is represented by means of the momentum thickness.
