ROCKET AERODYNAMIC RUDDER Russian patent published in 2014 - IPC F42B10/16 

FIELD: transport.

SUBSTANCE: invention relates to rocketry, particularly, to folding airfoils and opening mechanisms. Unfolding rudder consists of the shaft fitted in rocket body to turn therein, airfoil to be locked as-unfolded and articulated with said shaft, rudder unfolding mechanism with spring-loaded pusher. Said pusher is connected with airfoil by train. Rudder unfolding mechanism is arranged at rocket body in direction of rocket flight, perpendicular to rudder rotational axis and composed of rocker with cut-out articulated with the shaft. Roller is fitted in said rocker. Groove is made in roller body to accommodate the cable with one end secured to spring-loaded pusher and opposite end articulated with airfoil. Said airfoil is made solid.

EFFECT: rocket unfolding rudder with small-size shaft and narrow-profile airfoil to be fitted in minimum clearance between transport-launch barrel and rocket body.
