RT Journal Article ID 110493935342ade7 A1 Ding, Zeshong A1 Liu, Yafei A1 Chen, Shaosong T1 A Study of Drag Reduction by Base Bleed at Subsonic Speeds JF International Journal of Energetic Materials and Chemical Propulsion JO IJEMCP YR 1991 FD 1991-01-01 VO 1 IS 1-6 SP 241 OP 250 AB This paper presents the experimental research results of the drag reduction rate of the base bleed of solid fuel-rich propellent column at subsonic speeds. The experimental range of Mach number was from 0.6 to 0.98. Experiments show that the base drag can be removed by the base bleed of propellent column under the range of M = 0.6−0.8. The Bowman-Clayden's empirical formula, which was widely used, is not applicable in this speed range.
