DEVICE FOR FIXATION FOLDED AERODYNAMIC SURFACES OF AIRCRAFT Russian patent published in 2010 - IPC F42B10/14 

FIELD: transport.

SUBSTANCE: invention refers to aircraft (AC) with folding aerodynamic surfaces, in particular to devices for their fixation in folded position. Device for fixation folded aerodynamic surfaces of AC consists of unit providing adherence of folded aerodynamic surfaces to aircraft and stopping executive device installed on AC. The mentioned unit and device are detachably interconnected. The unit providing adherence of folded aerodynamic surfaces to AC includes connecting, adjusting and fixing elements and is installed in marginal zone of aerodynamic surface tip in hollow of blind hole. Blind hole is made in that pert of tip which is opposite to direction of AC movement. The first end of connecting element is embedded in blind hole with possibility to be adjusted and fixed at the moment of tightening. The unit providing adherence of folded aerodynamic surfaces to AC is connected with stopping executive device by the second end of connecting element and through it projects beyond AC aerodynamic surface tip. In the area of connecting element egress from aerodynamic surface tip reinforcement is made.

EFFECT: improvement of fabricability of device for fixation folded AC aerodynamic surfaces and AC aerodynamic characteristics, and lowering of aerodynamic surface mass.
