Wing of rectangular platform with its own aerofoil section is of frame structure with two spar tubes and the system of diagonal struts and system of ribs. Al-alloy tubes of 63 mm diemater are reinforced in the hinges regions by tubes of corresponding diameter. A system of ribs consists of 14 ribs and of 13 aux. ribs supporting the fabric skin in the front wing area. In the horizontal plane the wing is braced by a system of diagonal steel spar tube. The 2×25,5 l fuel tanks are housed in the wing root part. Tanks are welded from Al-alloy sheet. The leading edge shape is guaranteed by a fiberglass part bonded in front of the spar tube. The trailing edge is fitted with an Al-alloy shaped batten. The wing is covered by synthetic fabric POLY FIBER, with applied stretching lacquer and sprayed by a first-rate exterior enamel. flaperons (Junkers flap) are attached through five hinges to the ribs under the wing trailing edge. The flapperon structure consists of Al-alloy tube and laminate sandwich (foam, epoxy resin, glass) formed in a negative mould. Both wings are attached to the fuselage in the upper part through the main tube hinges and in the bottoom part by the hinges of the “V” ‑shaped wing struts. The system of common rear wing hinge and tilt truss axes allows the wing to tilt along the fuselage rear part. This saves a lot of storage place and allows the road transport.
The EuroFOX “wingfold” is just that, wing fold…… one person can open or fold the wings, single handedly in less than 5 minutes, no tricks, no heavy lifting or any extra hands needed. The EuroFOX wingfold was designed from the outset and an integral part of the aircraft, not an afterthought as so many other “wingfold” claims are.
