Control systems and servo electric control surface actuators

Control systems and servo electric control surface actuators of high-precision weapon: - antitank guided missiles; - short-range guided air missiles; - corrected air bombs; - short-range and medium-range anti-aircraft guided missiles; - naval torpedoes. Control systems can be single-channel, double-channel and three-channel systems. They have an alternative adaptive structure and ensure high guidance accuracy. Actuator control systems are aerodynamic, gas-dynamic control surfaces, and also combined actuators.
