We continue to publish models of rotochutes — winning flying competition for the Cup named after S. P. Korolev. Model Cup holder yurtaeva S. (Moscow) are described in the “Modelis-the-designer”, No. 4, 1999 Today we offer developed by the Tsentr detskogo tvorchestva g. Nizhnekamsk, under the leadership of teacher A. N. Rossiia rotocut, which was the prize-winner of these competitions V. Stolyarov. Model rotocut class Ѕ9А — lobed. The fuselage is in two parts: the rod and propulsion of the container; the connection — telescopic.
Work on the model begins with the manufacture of the fuselage. First, on the mandrel with a diameter of 10.2 mm roll container made of two layers of fiberglass with a thickness of 0.1 mm and cut along the length 125 mm. In the lower part of the fixed tail fairing lime. It has three longitudinal grooves with width 4 and depth 3 mm for placement of clamps blades. Then on the outside of the fairing around the circumference-~ mathiaut four layers of thread, which, in turn, will keep the blades from disclosure.
In the upper end of the container is glued face frame with a hole diameter of 6 mm. In the wall of the container, drill drainage holes (5-6 pieces) for gas exhaust when triggered, expelling charge.
Rod length of 300 mm, and the container vyklevyvajut of glass on the mandrel diameter of 5 to 5.5 mm. you Can make it from wood, but then its strength will be lower.
