In this paper the dynamic behaviors of seme devices of the M-4S rocket are analyzed and discussed, which consist of (1) the separation ol the strap-on boosters for increasing the thrust of the firrst stage, (2) the opening of nose cone, and (3) the deployment of the flare to make the second stage aerodynamically stable. The paper also includes the experimental results of the aerodynamic characteristics of the conical flare, the surface of which is oartlv cut off.
