The Transfer Function of a Rocket-Type Guided Missile with Consideration of Its Structural Elasticity

Assuming that the pitching or yawing motion of a rockes type guided missile under the influence of thrust and air forces normal to its longitudinal axis can be described by the motion of an elastic free-free beam with given mass distribution and given stiffness distribution, the transfer function of the missile is de duced. It relates the deflection angle 5 of the control agent to the angle 0o measured by a displacement gyro at any point xg on the longitudinal axis of the missile. This transfer function is to be used in future investigations to replace the simple transfer func tion of a rigid body in the block diagram of the overall missile control loop.
