AERIAL VEHICLE WITH UNFOLDING FINS Russian patent published in 2009 - IPC F42B10/14 

FIELD: weapon.

SUBSTANCE: invention relates to missilery, particularly to the aerial vehicles with variable areas of the lifting planes. The aerial vehicle contains a stabilisers, each of which is made in the form of a fixed base with a fin which can be shifted, fin lock mechanism and opening drive of fins. The fixed base has guides placed along the both of its ends, and lock mechanism contains locking devices fixed on the guides by pairs, one pair of the identical locking devices is fixed in the root section of the guides, and the other one - on the guides in the distance of the motion of an unfolding fin. Each locking device has a lock, and a part of the fin moving from the guides contains grooves made with the possibility of being interacted in pairs with the locks of the locking mechanisms.

EFFECT: improvement of aerodynamic properties and opportunity of regulating extension force of the fin moving from the standstill.
