Participants and guests of the all-Union review-competition of self-made ATVs in Arkhangelsk were surprised to find that in the city there is a whole Amateur “industry” for the manufacture of such machines on the low-pressure tires. And the scale of it so large that it can only be explained by a rare combination of factors such as the availability of the industrial base, proximity to nature with its roadless spaces and a large number of enthusiasts. Characteristically, acquire pneumatic-tired machines and townspeople, and villagers: for travel on fishing, hunting, mushrooms and berries. Consider also that for some it is the only vehicle suitable to local conditions.
Recently outboard motor was held in high esteem by the water-tourists. However, in recent years a large part of the waters became inaccessible for boats with internal combustion engines. Once again had to recall the sail, to once again take up the oars — Many, however, are not satisfied with traditional propulsion with a muscular drive efficiency the same oars is not too high. No wonder at the time, the paddle wheels were literally pushed by a propeller.
Our magazine has already talked about year-round windsurfer, is able with equal success to move on the water, snow and ice (see “M-K” № 11, 1987).
Our magazine was one of the main popularizers of the recently introduced family of ATVs — vehicles for low pressure tires. All season, excellent permeability, the ability not to disturb the vegetation when moving through the forest or the tundra — the dignity of vehicles of this type immediately attracted the attention of lovers of Amateur technical creativity. And after the publication of the drawings one of the most successful designs — terrain vehicle “Harp” Vyacheslav Laukhina (see “M-K” № 5, 1984) — in our country there were hundreds of machines of the same scheme.
When these elegant cars appear on the road, they arouse the interest of others. Yes, and how not to draw attention to the two (already “series”!) exactly the same jeep, eye-catching beautiful design and sophisticated rational design! At stops I had to hear the puzzled questions: “What is this machine? The new model UAZ rural version of the “Niva”?” Drivers — and they are also the designers of their ATVs smile: “No, it’s not “field” — “Neva”!” Puzzled by the response of passers-by in disbelief considering the cars and do that in front of them homemade — so a “factory” they look.
The question posed in the title, still have not found a final resolution. The first experiments to replace the traditional sail is a vertical wing, by profiling and design friends of the aircraft, did not bring the expected result. The fact that hundreds of years of its existence, the sail turned into a beautiful multi-device for conversion of wind power into thrust, informing the movement of the ship or the Buer. And it works quite effectively, and acute course, with strong and weak wind, his smooth flow and in the squalls. In addition, the sail is a great tool that allows the helmsman to accurately adjust it in accordance with the selected rate and direction of the wind, its force arising from the roll of a sailboat and other motion parameters.
29.09.2012 G. has a new plane the boat under the designation L-31 and “New Faith.” Now the aircraft has been tested in acquitting all the calculations and hopes. Manufactured flying boat in the Samara aviation sportunterricht club under the direction of G. Annenkovo. L-31 means: the triple boat with a single engine (Rotах-912).
AIRPLANE FOR TWO. Most of aircraft fans, began his career in aviation with the construction of a single aircraft in the end come to the conclusion that such machines are extremely limited – to fly them only in calm weather; two-stroke engine is reliable, that does not allow the pilot to depart from the aerodrome; any significant cargo on such aircraft can’t be transported, and for learning single aircraft is not suitable.
