RC ROCKET PLANE | MODEL CONSTRUCTION

In 1980, the sub-Commission on the rocket modeling of the FAI decided to introduce a new class of raketoplana S8E with a maximum mass up to 300 g engine with a total impulse of 40 n*S. Model of this class, created by Bulgarian athletes participated in the competitions and showed good results. Having the necessary materials, it is easy to make in the flying circle. The engine of rocket with a total impulse of 40 n*works for 10 s. To control the model can be used in compact radio equipment “Craft” or homemade equipment, the mass of which does not exceed 80 g. Usually its the power supply applies a battery capacity of 0.1 Ah and a voltage of 4.8 V.

The model design is traditional. The fuselage is of rectangular section made of balsa plates with thickness of 1.5 mm To the bottom with amelita or glue AK-20 are attached to the sidewall.

Them epoxy glued aluminum guide tubes for the control rods going from the servos to the control horns of the elevators and turn, and then glued the upper hull.

Ahead installed on the fuselage pylon balsa 6 mm thickness To it based on epoxy resin is attached to the container for the engine, laminated of fiberglass, impregnated with epoxy resin. In the front part it is provided with a cowl carved from balsa. To increase the strength of the forward fuselage and pylon are pasted over with thin fiberglass.

Instrument control is in the front part of the fuselage. First mounted the battery, then the receiver and servos, one after the other. The battery and receiver mounted on rubber shock absorbers, and servos mounted in the fuselage in place with the balsa bosses and screws.

R / C model rocket glider:

1 — engine, 2 — container, 3 — fairing, 4 — battery, 5 — pole, 6 — receiver, 7 — M3 screw marked leading edge of the wing and 8 servos, 9 — boss, 10 — nut M3 11 — M3 screw securing the rear edge of the wing, 12 — lower fuselage skin, 13 — upper fuselage skin, 14 guide, 15 — Kiel, 16 — rudder, 17 — horn 18 — joint 19 — stabilizer, 20 — Elevator 21 — side panel, 22 — rear flange, 23 — cover, 24 — rib, 25 — spar 26 — tough sheathing, a 27 — front edge.

The wing ribs are balsa, with a thickness of 1,5 mm; from the same material are made the front and rear edges of the wing thickness, respectively, and 4 mm. Shelves longerons from pine slats with a cross-section 4X2 mm pads on the ribs balsa veneer — 3X1 mm. Central part of the wing bottom for screw fastening is enhanced by the strip of plywood with a thickness of 1 mm and a width of 40 mm. the Front part of the wing is sheathed with balsa with thickness of 1 mm. Then the wing is glued with silk or mcalenney paper impregnated with Amalita. Stabilizer, as all elements of the tail, balsa plate thickness 3 mm. the Center of gravity is 50 mm from the front edge of the Central section of the wing. The rocket plane can fly without installing any radio. In this case, instead of the equipment in the nose of the fuselage to fit the ballast.
