TIMER MODEL “SWAN S-02”

This publication, we discovered in our magazine the best models of the competition “Experiment 78”. I hope that our readers are using these materials, prepare an interesting model for the competition “Experiment 79”, which will be held in Izhevsk in July of this year. To participate you must hold a qualifying competition. The winners of these meetings will form the team “Experiment 79” your area, region. Look forward to hearing about how he held a local competition in experimental models.

 

This time the model of “flying wing” has an unusual scheme: the angle of sweep — back and is 20°. In this form the wing is easier to implement center of gravity, necessary to provide longitudinal stability and balance.

 

Wing imparted a positive angle of rotation of the end portion (in the place of the fracture) relative to the center section +3°. For the best lateral stability the wingtip rejected up the ending — “ears”, which occupies 1/3 of polurama each. They have the added angle of transverse “V” 15° and the angle of turn inside 13°. The wing profile is applied with a relative thickness of 9% — “MUNCH-6”.

 

Wing — two-spar, with braces. Shelves pine spars, their stench made of balsa wood with a thickness of 1 mm. Front edge of the dugout from the lime. The forehead of the wing is sheathed mm balsa with veneer — top up to 30% of the chord of the wing, and the bottom — to the front spar. Ribs out of balsa with thickness of 1 mm. Twelve reinforced ribs is made of basswood with a thickness of 0.8 mm. trailing edge pine.

 

The wing consists of three parts — center section tightly connected with the fuselage, and two outer consoles. It is attached to the center section by means of two pins, each recruited from three stainless steel plates with a thickness of 0.8 mm.

 

 

 

 

For balancing the model in flight the engine has a plate sickn that slant down for 10°, 1 sec after turning off the engine they

 

pressed to the wing and provide balance in the planning. In this part of the shield (made of anodized aluminum with a thickness of 0.3 mm) stands for the trailing edge of the wing. So there is a rebalancing of the model from the engine in flight planning. The presence of this system allows to use the full power of the engine and requires no deviation of the axis of the motor downwards. Model at 30 with the engine run scored in the five rounds of the total duration of 457 with (32 + 41 + 158+87+139). This was shown best result in the class of timed models of “flying wing” in the competition “Experiment 78”.

 

The total area of the wing — 37,34 DM². Flying weight of the model 750 To model KMD-mounted engine with working volume of the cylinder is 2.5 cm³.
