This is another publication about new ways of use of the Bicycle the inventor, V. M., Gavrilova — the inhabitant of settlement Inozemtsevo area of Zheleznovodsk in Stavropol region. Previous publications in magazines “modelist-Konstruktor” No. 10’97 and № 5’2000
Great interest of young innovators, professionals of various industries has caused organized at ENEA USSR tematicheskaya exhibition “Inventors of Latvia — production”. And especially the fact that she showed an interesting experience of “planning” inventions accumulated e Republic, there are organizations pioneering the search on the most pressing, important for the national economy problems.
The proposed model has a classic pattern glider A-2 “Hawk” in a reduced form. The main material for its construction – balsa. I must admit that over the last three or four years, such constructions appear frequently in competitions of any scale (though the schoolchildren they are made of more affordable material – to-ceiling foam). A return to this scheme due to the stability of the flight of such a rocket plane. Except only on the runway (starting) station.
The competition rules for models raketoplana prohibit use for take-off surface, creating aerodynamic lift. Flight model can be scored if, at the time the hoist is used only reactive SIPA engine.
Offer paired schematic model made in model aircraft laboratories of the station of young technicians in the city of Nikopol. Structurally, it is a “aviamarch”, consisting of carrier-glider attached to the carrier special locks rezinomotornaya model airplane.
In the early 70-ies before the Soviet athletes-automodellista was a challenge: dvuhsotmetrovy to exceed the threshold speed in the class of models 2.5 cm3. These days, the speed has mastered many of the leading athletes. A sharp jump occurred in 1973, when during the season a few models exceeded the speed of 220 km/h.
The triumph of the Soviet athlete V. Extencive in the class of models of gliders ended the world championship in 1973. Short nose and a relatively small shoulder are the main design features of the model of a champion. The layout is very different from the standard, which is used by most of our leading modelers.
How to ensure reliable and trouble-free fit of a model rocket? The solution to this technical problems struggling for many modelers. According to statistics, more than half of the models after the descent have breakage. But time goes on, experience is gained, more diverse ways of salvation models.
You can put on the car 4, 8… even 16 wheels. However, in the tundra, for example, even this machine will not work and kilometers. And no wonder that whole design teams engaged in the search for new propulsion, which would come to replace the wheel and provided all-weather cargo delivery, hauling of the forest, the work of the search parties… Already established for this purpose samples of tracked vehicles with very broad, almost 1.5 m tracks, snegokatov, hovercrafts.
As described below, the thresher works on the principle of rolling corn cobs in the progressively narrowing gap formed between the cylindrical drum and concave with rubber surfaces. Cob, salinitas between the drum and the cover, rotates around its axis, while it is separated from the grain.
