OPENING MECHANISM OF AERODYNAMIC RUDDERS OR WINGS Russian patent published in 2020 - IPC F42B10/14 

FIELD: astronautics.

SUBSTANCE: invention relates to controlled rockets, namely, to mechanism for unfolding collapsible aerodynamic rudders or wings of unmanned aerial vehicles. Opening mechanism of aerodynamic rudder or wing is located in cavity of axis of rotation in the form of torsion block, connected by its one end to fixed part, and by another - through cocking mechanism to rotary part. Torsion unit represents cylindrical torsion located between two packages of plate torsion bars fixed on ends by inserts.

EFFECT: technical result consists in optimization of overall dimensions of aerodynamic rudders or wings in folded position while providing unfolding force in conditions of powerful incident flow, as well as in improving reliability.
