    Abstract

    Experiments have been made to assess the effectiveness of passive devices for reducing base and total afterbody drag at Mach 2. The devices examined include primarily base cavities and ventilated cavities. Results show that ventilated cavities offer significant base drag reduction and net drag reduction of engineering value. A correlation for base and net drag reduction for ventilated cavities has been suggested.
