AIRCRAFT CANOPY OPENING-CLOSING CONTROL SYSTEM Russian patent published in 2005 - IPC

FIELD: aeronautical engineering; canopy opening-closing mechanisms.

SUBSTANCE: proposed system includes swing section 2, fasteners for securing it on fuselage, suspension 3 and fasteners for securing the swing section to suspension. Suspension body has at least one first member secured on front wall of suspension and connected with second member 24 which is articulated with at least one rod 30 connected in its turn with fuselage by means of axle 18 and second member 24 connected with drive. Secured on suspension are first guides 16 limiting motion of rods, second guides 31 with horizontal and vertical sections for motion on fuselage rollers; at the rear there are brackets with slots for axle 18 and projections 13 engageable with limiters 19 mounted on fuselage. Drive is made in form of pneumatic hydraulic cylinder 9 with breaking rod. One motion of pneumatic hydraulic cylinder makes it possible to open, close or jettison swing section of canopy.
