REINFORCED WING ON THE “SCHEMATICA”

Wings of schematic models of gliders do not usually have a large margin and when tightened on the guard rails inexperienced athlete fall into a flutter or fold overload!

Especially often such picture can be observed in a strong wind. A model designed in our group, has a strengthened wing and “forgiving” rough puff.

Rigidity is achieved by the installation of two additional rails, which serve as braces and center section.

Wing going, as usual, V-shaped, but without the Central rib. Then glue these two strips of the wing and ribs.

Although these slats and increase the weight 3-5 grams, but the rigidity and durability of the wing are greatly increased. To build the model, we use the following materials. Raked wing — pine 4X4 mm.

Ribs and fins — bamboo, plywood of a thickness of 1 mm or aluminum wire.

The fuselage with the pine rail 8X6 mm.

Hog of lilac plate 8 mm thick with a cutout for relief. Underneath the rake of the fuselage is attached to the launch hook wire OVS Ø 1,5 mm. Wing, stabilizer and fin are covered with colored paper.

Schematic model of the airframe with the strengthened wing:

1 — cargo, 2 — horn, 3 — hook, 4 — body, 5 — keel 6 — stabilizer, 7 — wing.
