“FLYING WING”: THE GLIDER, TIMER

The fuselage consists of a pylon and the tail boom. Pylon cutout to set the timer and mounted on this motor mount is made of plywood with a thickness of 8 mm. On the last fixed top fairing made of pine, bottom is attached to the end ribs of lightweight Linden and pine sticks, which are beyond the pylon the tip sawn off. This is done for ease of wing mounting and motor for better aerodynamics and mass balancing models set the cylinder down.

 

Beam of the fuselage of planed pine slats and inside lightweight. Keel — stacked, too, from pine slats and ribs carved from Linden veneer. His profile is symmetric, 6%. The rudder is made of foam, the edges are covered with pine rail.

 

The wing consists of two parts — a carrier and stabilizing collected from pine slats and lightweight ribs (plywood with a thickness of 1 mm). Ribs made of plywood with thickness of 3 mm, the struts are made of steel wire Ø 2 mm (elements — of duralumin plates with a thickness of 1 mm).

 

For a tight joining of the wing to its end the ends have hooks made of steel wire Ø 1.5 mm, the rubber pull the wings tight to the ribs of the fuselage. The stabilizing part is mounted fixed round dural pin. To install the angle on the end bearing surface are the clips.

 

Both parts are tightened the rubber, which simultaneously serves to rotate 90° to the horizontal stabilizing pieces when forced descent model.

The “flying wing” Prokhorov used the standard engine KMD-2,5. Screw pusher Ø 200 mm with step 100 mm Weight — 900 g.

 

Her flight is in the motor mode with the right turn, and planning — with the left.
