GUIDED PROJECTILE Russian patent published in 2003 - IPC

FIELD: jet artillery ammunition. SUBSTANCE: the guided projectile has a body frame with aerodynamic control surfaces installed in the journals of the drive shafts. The central holes of the shafts accommodate the pistons of the gas engines of the control surface deployment and fixing mechanism. Introduced in the projectile are cylindrical locks located in the central holes of the drive shafts between the pistons and the control surfaces, and springs installed between the pistons and locks in the end bores made in them. Shoulders are formed in the central holes of the drive shafts on the side of the journals, they are engageable with the shoulders made in the pistons, and the locks are made of a more soft material as compared with the materials of the drive shafts and control surfaces. EFFECT: provided deployment and fixing of control surfaces in the process of manufacture of the projectile for in-process checks and tests of the control system. 1 dwg
