CONTROLLED PROJECTILE Russian patent published in 2009 - IPC F42B15/00 

FIELD: weapons.

SUBSTANCE: invention is related to rocket armament, in particular, to the field of small controlled projectiles. Controlled projectile is arranged in compliance with canard layout and comprises air-dynamic steering linkage in head compartment of body with air intake and rudders. Side air intakes are installed in head fairing of body in front of rudders in the same plane with rudder cantilevers. Air intakes are arranged in the form of box-like biplane bearing surfaces with air intake through inlet window, with ratio of window height and width equal to 0.9…1.1. Rudder cantilever is arranged with alternating angle of sweep along front edge, namely, with 0° angle from board chord to 0.3…0.4 of one cantilever swing, and further with sweep angle to front edge of 55…60° to complete swing of rudder swing. The highest efficiency of projectile control is achieved by optimal selection of ratio between geometrical dimensions of rudder and air intake. All that makes it possible to considerably increase rudder control force, to reduce hinge loads, which in its turn makes it possible to increase efficiency of control, to increase arranged projectile overloading. Besides, it makes it possible to simplify air intake design, to optimally used layout of head department.

EFFECT: increased efficiency of projectile control, reduced weight and size characteristics of steering linkage, increased ballistic characteristics of projectile, simplified design of head department of projectile body.
