The model aircraft easier… Bought a compression motor, collected from reechek Yes nervures wing, planed boards from lime simplest fuselage and fly the model! And this is the simplest aircraft will be in principle the same as control line aerobatic acrobat experienced athlete. Another thing — avtomodelisty… Even the most simple of our “shells” contain chiseled, sanded, milled, hardened, normalized, machined, planed, moulded, blue, chrome, vulcanized etc. details to make that possible only by using modern high-precision equipment. How to organize with the mass boys! Once rescued us, heads of circles, sets of parcel Temp. However, their basis virtually did not leave the club room for creativity.
We offer our readers a model class S4B (raketoplan) designed by the famous Soviet athlete A. by Karapinar common aerodynamic configuration “duck”. She translates from planning mode to parauterine (forced landing) due to the deviation partneremployees stabilizer in the vertical position.
Exactly the same as a modern car, soft suspension is needed and its radio-controlled models-copies. After all, the impact of the model on the ground or, conversely, jump over a depression in the road surface lead to vertical oscillations of the wheels of the car that is transferred to the axles and the body. Hard suspension a strong impact on the wheel during motion leads to a separation from the road the entire model. To avoid this soft suspension allows the wheel.
Weather service uses a variety of research methods. One of them is the distribution of atmospheric parameters on height. To quickly solve this problem scientists helps small uncontrollable meteorological rocket MMR-06 with solid engine. The maximum height of ascent is 60 km; the instrument complex allows to measure the temperature and pressure of the air to determine the wind velocity vector. Information transfer to the ground by the telemetry system.
We present rocketmodeler development contains many non-traditional solutions. I hope that they will interest the creators of “microcosmic” technology of today and will be useful to those designing models for the future sports season.
Case microsociety class S6A (Fig. 1) champion 1986 A. mityureva formed of two layers of fiberglass with a thickness of 0.025 mm and subsequent treatment with sandpaper. The mandrel of variable cross section, largest Ø 18 mm, and a minimum of 13.2 mm. Aft of the case is tapered, with the last 7 mm of the length it is cylindrical, above — the length of 30 mm to a transition cone. The length of the main cylindrical portion 89 mm, the bottom glued the balsa frame with a hole beneath the engine. This provides accurate setting of MRD. The frame is made of a radial hole for fixing studs of the engine. Stabilizers balsa, with a thickness of 0,7 mm. the lateral side reinforced with fiberglass. Fairing fiberglass. It is pasted inside a frame. Join the corps — through mounted in the spinner.
It is not easy to be “protanium”! As in any other class of modeling, the success of his performance depends on the number of workouts. And how to look forward to the end of the long winter to come up with a model for the wet melting snow from the track and begin a new sports season! He flies quickly: in only five months. The rest of the year can only be used for the construction of new equipment. So if we had to continue training all year round! But it is hampered and the lack of winter sites suitable for starting, and poor performance nitro engines in the cold. And the use of such “exercises” stiff arm a little.
Today we introduce modelers-students with two versions of microart class P. the Elegance of the external lines, simplicity of design and manufacture — this is an incomplete list of advantages of these models, designed and built by young athletes Moldovan CSUT under the guidance of an experienced teacher, a veteran of labour and fleet D. Vysheslavsky. Using new technology, children have made significant weight reduction of the housings and the models themselves. Steel yachts virtually unsinkable, increased their rapidity. As soon as the young modelers have gained experience of commissioning models and the ability to feel the weather, the performances microparasite this type of steel to bring them consistent success on the scoring starts.
Today we want to introduce readers passionate about rocket modeling, with interesting design, developed and applied with success in competitions Czechoslovak athlete Joseph Rihoy. In 1983, the model helped him to achieve high results: in the championship of Czechoslovakia, he was a silver medalist, to become the first it was allowed only an unfortunate accident — the parachute didn’t open in the last round, it happened because of moisture on the dome at the last landing in the wet grass. It should be noted that the champion of the competition used the model of such a scheme.
To design a proposed “bouzouki” we came after a careful viewing of many descriptions and schemes of modern models class F2D. Reasoning that the current “fashion” for rough terrain foam machines is justified, decided to retreat and in General repeating the technique of elite athletes. As a result of the sketches turned out to be a promising model, the construction of which is possible with minimum consumption of balsa. We managed to get rid of complex operations on internal relief foam brackets: with fuzzy selection of this material imminent significant leashes and distortion of the profile of the wing ready. Relief parts due to the through-holes allowed to keep a lot of “frame” (and in the end, the flight properties of the model) to the desired level.
