Radial jet group missiles steering device - aligns missile's longitudinal axis on target by selective thrust control of nozzles paired in orthogonal planes

摘要

A ground-target seeker (1) measures the angle between the axis (X) of the missile and the line of sight (Y) of the target. An amplifier-compensator (4) produces a differential thrust command signal (delta T) while an amplifier-integrator (5) provides a signal proportional to the lateral thrust (T) for alignment with the target. Sum and difference signals (6,7) are imposed on a sawtooth carrier wave (8) to generate variable-width pulse (9,10) for electromagnets (11,12) operating forward and rearward pairs of diametrically-opposed radial nozzles (2a). ADVANTAGE - Missile is controllable even at low speeds where aerodynamic external rudder surfaces are ineffective.
