FIELD: transport.
SUBSTANCE: device is arranged in aerodynamic surface stationary part and comprises work chamber with piston coupled with aircraft pneumatic system. Piston interacts via coupling element with bracket whereto aerodynamic surface movable part is secured. Unfolding is performed by increasing work chamber pressure to make piston move and bracket turn. Aerodynamic surface completely unfolded, it is locked by spring-loaded rods that enter the bracket holes.
EFFECT: higher efficiency.
