1. GENERAL PROVISIONS
To drive in many modern pneumatic machines and tools required compressed air pressure of 3-4 ATM. Is it possible to build a mechanism which effectively would have used a pressure slightly above atmospheric? It turns out that modeling proves it.
Many can make a shift to summer camp? Because it ends so quickly! And no matter how much enthusiasm in the students-smart, funny, summer time beckons them to postpone for a time the tools to escape into the forest to the river or to play football. But there are models that even beginners have time to build just a few classes. And not only build, but also want to experiment with them and compete. These include models of a wheeled yacht. The smallest automodellista it is possible to offer a simple boat. Composing elements in different ways, it is easy to create the most unusual “asphalt sailing”.
The tillers, was developed by Genrikh Alekseevich Kuznetsov from Moscow, is different from many homemade designs use instead of the plow cutters. Turning to the work shaft at the same time they cultivate the soil, serve as support elements and propulsion. Only a few minutes required to replace them on the wheels. Then the tillers are easily hung disc mower, dozer blade, trailer plow, mouldboard, the disc harrow, or a two-wheeled dump truck with a lifting capacity of 300 kg, are equipped with brakes. With the help of special tools you can handle a bed of strawberries, to transport logs.
Devices leading only pilots, in General, very similar in scheme and design are very different in administration. The reason is simple: everyone builds a microplane “under his hand”, presenting to him the more requirements, the higher the class of the constructor. But even the slightest innovations often lead to a significant change in the flight properties of the model. Therefore, when designing pilotazhki impossible to do without hints of a rich and practical flight experience, solid theoretical knowledge.
None of the types of modeling to the apparatus is not presented at the same time so many conflicting claims as to RC jumper gliders. Imagine that you need to design a machine that combines the properties of high-speed models, gliders-paritala and apparatus created specifically for ustanovlena of records range.
RC model aerolaser (Fig. 1) easy to manufacture, and it does not require scarce materials. Do this even for a Modeler with a little experience, and so the airboat could become a learning model figure chart. This boat great sailing qualities: it handles well, quickly leaves on glissirovanie, stable moves for all evolutions, sufficiently stable. Even with a strong gusty wind model but out of control.
“Eureka” is the Dinghy to the simplified construction, designed for home fabrication technology. The hull of the Dinghy — wooden, lightweight, with the lining membrane type. It consists of three bead frames, keel and four stringers. Midel-frame — reinforced, as it mounted mast and additional parts. The mast of the dural tube or wooden, swivel. The sail is a Latin, with a mainsail area of about 3.2 m2. Additional parts of plywood hinged in the dural tube, sealed at the midship frame.
Avtomodelistov riders as it is not accepted to give the models names. Perhaps that is why the first thing we asked the author of this has no similar model, the origin of its name — “Vyatka”. Instead of a response, the designer withdrew from subtle glass-plastic fairing. It was very similar in layout to those produced many years of domestic scooter VP-150 Vyatka: console attached to the engine block the rear wheels, the engine — side of the longitudinal axis.
The bread baked in the village oven, needs no advertising: all articles del. Only here to store sacks of flour troublesome, much easier — the grain. And therefore, it is necessary to be able to grind grain at home without having to travel to mill. And get the flour as fine and coarse. At home in the village often have to roughing of grain, sunflower, tear down and to grind chalk, salt, various grain waste. And prepare feed on his farmstead — the dream of a villager: livestock and poultry in private households is increasing day by day.
