DEPLOYABLE RUDDER Russian patent published in 2016 - IPC F42B10/14 F42B10/64 B64C9/02 F15B15/26 

FIELD: rocket science.

SUBSTANCE: invention relates to rocket engineering. Deployable rudder comprises funnel folding part of steer (1) and root part (2), fixed in drive (3) of rudder and installed in housing with possibility of rotation, and drive (5) of rudder opening with rod (6) for its longitudinal movement. Rod (6) is connected with foldable rudder part (1) by connected in the root part (2), rocker (7) and clevis (8). On deployable part of rudder is tooth (9) providing in deployed position fixation of foldable part (1) in root part (2) with spring-loaded latches (10). Pumping unit (7) comprises tooth (11) of rudder locking against rotation in folded position, interacting with bracket (12) on fixed part with disposable removal of locking at turning rocker (7) at moment of rudder unfolding. Use of rudder unfolding device can be widely used in rocket engineering, where minimum dimensions and weight have priority.

EFFECT: higher reliability of rudder locking against rotation in folded position.
