Sidejet Aerodynamic Interaction Effects of the Missile

Abstract

The side thruster is a highly responsive means for attitude control of missiles. The sidejet force is influenced by the interaction of the sidejet with the external airflow. The sidejet aerodynamic interaction effects were analyzed from following two viewpoints: 1) the pressure field in the vicinity of the sidejet and 2) the force acting on the missile. Technical data of sidejet aerodynamic interaction effects were obtained by means of flight tests of missiles that were equipped with four impulse side thrusters that were small-size, rapidly burning solid-propellant rocket motors
