First of all look at the model-a benchmark that we have chosen as a “prototype”. This glider was created by the Dutch athletes, having rich experience and traditions in the design of paritala. This model belongs to the most modern developments and has a very high flight performance.
An airfoil having a double — V modified В6356в. The connector on the fuselage; the console must be mounted on two steel pin Ø 2,5 and Ø 2 mm, length 130 mm each. On the power scheme of the wing visible desire of the designer to facilitate the end portions from the mass to the center with a simultaneous increase of the stiffness of the center section.
Pine shelves of the spar section 1,5X5 mm (top) and 1,2X5 mm (bottom) in the “ears” to the ending flat out to 1,and 1. 5X3,2×3 mm. across the span of the spar is glued into the wall of balsa with thickness of 3 mm (1 mm “ears”). The root part of the consoles on the shelves are reinforced with additional longitudinal rails 2X5 mm. the Ribs are carved out of solid balsa wood with a thickness of 1.5 mm, and the first four power each console is made of plywood of 1.5 mm. Diagonal polonaruwa of the forehead is balsa with thickness of 0.8 mm. Front edge of the balsa with a cross section of 4X4 mm and reinforcing pine slats 3X3 mm. trailing edge balsa section 3Х17 mm. the Rigid skin of the forehead (obestochennye) balsa thickness 0.8 mm, together with the frame forms a rigid torsion caisson.
At the root of the first force between the ribs filled with balsa block, and the second sewn mm balsa. In places of transition between the center section and “ears” have ribs with a thickness of 5 mm. After separate Assembly of these parts of the wing balsa parts podskazhyte at V and are sheathed at the ends with plywood 0.6 mm. And at the interface between the two still embedded, and the balsa plate with a thickness of 0.8 mm. Cording wing — thin long-fibre paper.
