Talking about the Amateur designer E. Kulikov from the village of Bornukovo Nizhny Novgorod region, it should be noted that all of the units and mechanisms designed to facilitate the work and life of rural residents. Take one of the problems to be solved annually by villagers, and those living in most Russian towns, the firewood for the winter. Sawmilling “whips” on the wood stage in this process is the hardest and takes a lot of time and effort if cut manually. The same chainsaw is not all, and they are not cheap. That accounts for the villagers to cooperate using the same saw for a few yards at a time. Well, to chop the firewood is loose in the days of autumn or even winter.
the Impetus for this publication was a letter to the editor father and son Roganovich — our readers from the city of Pokhvistnevo Samara region. They sent a newspaper article entitled “Kurochkin invented the motor. “Toyota”, “Ford” and “Chrysler” panicked” and asked to tell more about this engine. Publications on this engine was not only in regional but also national press. You can learn from them about the fact that the invention protected by five patents of Russia, the international patent Bureau in Geneva notified the A. G. Kurochkin on the registration application and the temporary protection of copyright in 31 countries, including Canada, USA, South Korea, and Japan; some foreign car makers offered the inventor to continue working on the engine they have, but he refused, explaining the refusal by wish to leave his invention at Home, in Russia.
Double snowmobile “SQUALL-3”. With the advent of motoparaplane and trikes culture of designing power plants with propellers significantly increased, and today Amateur designers create rotor setup with decent traction engines using relatively small power. Accordingly, began to appear more frequently and wingless versions of these vehicles – hovercraft, snowmobile and aerolizer.
In one of the rooms “M-K” in the report from the championship of Russia on model rockets, I noted the rocket plane category S4 Nikolay Tsygankov team in Murmansk region. I must say that the chosen scheme with a large wingspan (about 950 mm) and elongation of about 20 provides good performance as well. This contributes to the convexo-concave profile of the wing, and elliptical shape of the bearing surface when viewed from above. And external contours of the tail look perfect. All this allows to a minimum to reduce aerodynamic drag. Originally decided N. Tsygankov and the problem of drag reduction during takeoff model. He used double-folding “ears” (consoles) of the rocket and to prevent the occurrence of flutter of the fixed wing is folded in three points (instead of the usual – in two points), securing the third hook-latch on the tail boom.
Offer readers acquainted with the original design of universal self-propelled tools, built by my brother Alexander. As he says (jokingly, of course), the idea of such a machine came to him out of laziness. Very much wanted all his life to do the heavy unproductive jobs, because, unfortunately, the village was not uncommon, when the peasant is forced to use antiquated agricultural tools.
Strange trail remains for these sleds, rapidly descending from the mountain: the impression is that someone drove on one ski. And only bends on the side added short stroke of the second track. Unusual sports equipment, the construction of which is available to all lovers of breathtaking skiing the steepest slopes, has developed our reader from Magnitogorsk Sergei Chadin. Made of wood, the sleigh combines originality of design and ease of performance. For their manufacturing are required Board or thick plywood and a saw.
But not to throw out it! And involuntarily thought creeps in to make it a foldable frame. The same as, say, the “Kama”. I reviewed the literature on the subject (including the publication in “M-K” № 3, 1990) and left unsatisfied — too difficult was the recommended design. Had to develop my — more simple. Tried it and now offer to the readers.
A kite is considered to be the grandfather of modern aircraft. This harness motorless soaring leader was the first aircraft in the so long ago, when there was still such thing — aviation. Unfortunately, in the future, kites were replaced by more udachlivey fellow sky — models of gliders and planes.
High speed RC model with electric drive is very popular with modelers-but-wickow and veteran athletes. This to a large extent contribute concise external form guide-registerof prototype that simplifies the design, allows you to make models from a variety of materials and used in the manufacture of a variety of technological methods — depending on experience, availability of certain materials and finished components (engine, onboard equipment and batteries).
The search for new solutions before the next sports season has led our members to very unusual for present-day design. In a subclass of HH-0.2 is now dominated by specialized yacht model. Basically it is a catamaran with a rigid sail-wing or newfangled pyramidal sailing tooling used again in mnogotochechnykh. However and those and others are clearly expressed signs of directions of designing of sports projectiles that have little in common with real yachts. So we tried to go back to the models one-korpusniki, refitting their sailing rigging. The fact that the classical scheme of a cutter with mainsail and staysail in its simplest initially losing performance in connection with birth defects tractive effort of the sails. We have used the so-called stukeley scheme (often referred to as the L-shaped mast). It has much better properties, as it provides the most Agnolo element snap — grotto — optimally and in a wide range of settings of the sails. Do note that designs based on technically sophisticated “bells and whistles” (like rotary wing masts and the like) are generally not considered when creating the model students all that’s out.
