The proposed model is a vivid example of technical creativity of Moscow’s leading athletes-taketomo-delicto that three years in a row became Champions of Russia in this category of high-rise models. One of the athletes — M. Stepanov, who won last year. Our story — about the design of his sports equipment.
The model is a two — step motors total impulse 5 Not. The first stage is equipped with engine pulse of 0.6—0.8 is Not. This model gives MRD initial acceleration and raises it to a height of 15-20 m. It is at this altitude occur the stages separation and the “hot” ignition of the engine of the second stage pulse 4.2 to 4.4 NS.
The case of the first stage length 220 mm formed on the mandrel with a diameter of 30 mm in two layers of fiberglass with a thickness of 0.25 mm. In the lower part glued two balsa bulkhead thickness respectively of 3 and 4 mm, which is a fiberglass tube inner diameter of 10.1 mm — motor container with a length of 30 mm. Outside, at a distance of 20 mm from the lower edge are bound with a wire pin-latch locking MRD from unintentional shooting. In the upper end of the container to first-stage engine glued the balsa plug, in which is fixed one end of ognevaya, the other end through the plug glued into the upper part of the body. Agnesod is a tube of carbon fiber with a diameter of 4 mm and a length of 183 mm.
