ABSTRACT	To obtaine data for stable recovery of future rocket boosters and the rocket itself,measurements of side force acting on blunted circular cylinders were carried out at high angles of attack (α＜32 deg.) in supersonic flows of several Mach numbers.The blunted circular heads,including a flat face and semi-elliptic shapes,were tested to determine the effects of nose shapes on side force.Highly blunted bodies close to a flat-faced cylinder show large side force as the Mach number decreases,while a flat-faced cylinder shows large side force in the narrow regions between M∞=1.75 and 2.25.
