Flow control with aerospike behind bluff body

Flow control in high-speed is challenging due to the high-pressure shock and low-pressure recirculation bubble attached around the vehicle. Wave drag, and Base drag are important accouterments of flow around high-speed objects. This paper deals with base drag, only and presents an experimental stu...

Aerospikes were found to be very effective in controlling base pressure in the transonic regime without influencing the main flow field.
