As can be seen from the drawings, this extraordinary apparatus looks like a giant glider model. The fact that it is equipped with a stabilizer which turns the wing into a self-regulating system that is automatically oriented in space relative to the wind direction as well as set an optimum gliding angle of a flying model.
The sail is a wing
The creation of the sail-wing begins with the manufacture of the mast (or, if aviation terminology closer to you — front edge). The mast, by design, reminiscent of the spring, consists of three pine plates.
Front (the longest) has a thickness of 30 mm, average 25 mm and rear 20 mm. If you pick up a four-metre long rail you do not succeed, then the blank can be glued with epoxy glue two shorter, docked ostrogannye “mustache” bar.
The wing has an asymmetrical profile, allowing to create a sufficiently large lifting force. The outline is specified with five ribs and front part of the mast, having a rounded shape, handled in accordance with the profile of the sail-wing. Rib of the wing is made of plywood 3 mm thick with edging strips of a cross section of 10×10 mm. For the relief of the ribs are cut holes. Near the trailing edge rib reinforced duralumin (s1,5 mm) plates. Fastening the ribs to the mast — in a thorn with reinforcements a couple of layouts from strips of 10×10 mm.
On each end of the mast is fixed a kind of spurs — the cut steel pipe, flattened on one side. When driving one or the other spur is inserted into the universal joint, mounted on a sports apparatus, used in conjunction with a sail-wing. The rear edge of the wing, resembling the bow of steel wire, allied with a diameter of 1.5 mm.
The wing connects to the stabilizer with beams of duralumin tubes with a diameter 40×1,5 mm or round pine bar of the same diameter, coated with “epoxy” with a couple of layers of fiberglass.
Universal self-aligning the sail-wing:
1 — edge-mast, front; 2 — the wing rib No. 2; 3 — wing rib No. 1; 4 lore; 5 — rib wing, Central; 6 — handle; 7 — edge of the wing, the rear; 8 — spurs front edge of the mast; 9 — all-moving stabilizer, swivel; 10 — edge of the stabilizer, front; 11 —edge of the stabilizer, rear; 12 — rib No. 1 of the stabilizer; 13 — rib stabilizer, Central; 14 — the Central beam; 15 — clip-retainer adjustment of the angle of attack of the stabilizer.
Fixing the trailing edge of the sail-wing on the rib:
1 — rib: 2 — flange, rear; 3 — retainer.
Rib No. 1 (a), rib No. 2 (b) and the Central rib (at) sail-wing:
1 — rail edging; 2 — rib; 3 — screws; 4 — pads; 5 —nail; 6,9 — bolts M5 shikami; 7 — a collar of fastening of the Central rib; 8 — clamp the trailing edge of the wing to the Central beam.
All-moving stabilizer design is similar to the sail-wing. The front edge consists of a pair of pine slats, the transverse set of three ribs. The trailing edge of the stabilizer, and the wing is from a 1.5 mm wire. The front edge of the fixed horizontal hinge, and on the Central rib — hog mechanism for adjusting the angle of attack of the stabilizer. The latter is connected a longitudinal rod with a steel clamp mounted on the beam. To adjust the angle of attack of the stabilizer yoke is shifted on the beam and fixed at a selected location with a bolt and a nut.
The wing and stabilizer can be performed in two ways. If you intend to do sports collapsible shell, the lining is made of fabric that is usually on the jackets. By the true dimensions of the wing of a fabric sostragivajut two “bag”, which dock along the axis of symmetry of the wing with lacing. Zone lacing is closed by a strip of the same fabric and secured to the skin with buckles, “Velcro”.
