The aircraft we design and build do not have booths in them, and the pilot’s seat. Yes, and they do not need aircraft with a five-meter wingspan and three-kilogram payload. “But then it’s not a plane, but only a model,” you say. I do not agree. Coming out of the walls of our body SLE-manned planes and helicopters — are real, and the tasks before them are very serious.HOW TO EASE RIB
Modelers know how difficult it is to facilitate fine rib, without violating its strength. In the model airplane circled our House pioneers a way of cutting out successfully replaced the cutting. This causes the strength of the part and the work is done much faster. Hole punch tubes of different diameter, with the end sharpened Read more…
It’s been over a decade since then, as avtomodelisty decided to make your sport all season and came up with kordovye model of the sleigh. Now, perhaps, it is difficult to name the author, the first such model: the necessity of introducing the lessons of the circles simple, affordable design that would combine the speed of production and the possibility to use the internal combustion engine, would the creative scope for the budding modeller and, moreover, would not be just “educational” (like, say, contour resonators), was clear to many.
Repeated attempts to rework expense of building a traditional model helicopters RC, as it was with model airplanes and gliders, were unsuccessful. This is because model helicopters, free flight, built according to a single-ended or coaxial circuits with rotating engines, do not have what is called a case. Simply put, they have neither the nose nor tail. Therefore, any movement for them, all except “up” and “down” is the direction forward. And control of the direction of motion of the model helicopter without orientated in space of body and the speed control of the movement, is impossible without swashplate. His on free-flying and so-called timer helicopters and no.
In the CSC-306 MAI constructed several devices with the power electrical system, but to talk seriously about the problem of creating a workable small elektroleta became possible only after supervising the Department has developed a unique brushless DC motor. It is characterized by light weight, high (95%) efficiency, and specific energy parameters 3-6 times higher than the corresponding characteristics of a known commutator motors.
Model airplanes still did not pay attention to a very promising engine, liquefied gas C02. But the simplicity of manufacture and operation make it much more affordable than compression and glow engines. In addition, it does not pollute the air and silent in operation. With this engine (Fig. 1) can operate a variety of aircraft weighing up to 100 g From one canister to siphon the tank (Fig. 2) can be refilled twice.
Model autogyro designed and built in the laboratory of the Aero modeling club of young technicians of the Siberian branch of the USSR. The author is a graduate of the class of technical physics and mathematics school Ilya Skiba. The model is made in Cordova. In this case adjusting it is easier than Svobodnaya. The design of the autogyro is quite simple. The fuselage, landing gear, empennage, engine mountings — as a conventional cord models. A three-bladed propeller creates lift, rotating from the incoming air flow, that is, using the phenomenon of autorotation. However, the number of blades may be three, four or more.
…Control knob soft is selected, the glider can easily lift the nose off the ground and shoots up. There, on a five-meter altitude, where popiskivaet on planes fresh wind, we are now going to demonstrate what they have learned to parry the roll of the glider, deviation from course, it’s a “press” machine to the ground, find the optimal angle kupirovaniya, which is necessary for a proper take-off… everything in this free flight! Meanwhile, our glider… can’t fly. Installed it on the building, resembling a well sweep. And is, in fact, the layout. To make such a trainer in the club or at the station of young technicians is not so difficult. It will allow children, dreaming of the sky, to practice a lot of exercises necessary for mastering flying skills.
For rowing and sailing vessels of the middle ages was used cetarehwodie anchors-cats and the two-horned anchor with a wooden stock, like the Admiralty, which appeared in the second half of the XIX century. In Portuguese and Spanish caravels and Galiano, Dutch flutes, Venetian trabaccolo and other vessels anchor in the stowed position suspended and attached sling through a block under the bowsprit or primitives horizontally to plancher bulwarks, whose strength is in the area of the school has increased due to additional brackets. To lift the anchors on these ships are applied blocks, chain blocks, arrows, hand-windlasses and wooden bollards. Mistake is made by those modelers that are on the model of a sailing ship belonging to the period of the middle ages, doing crumbly and spire. History of shipbuilding proves that these devices anchor devices appeared only in the second half of the seventeenth milestone.
Control line racing model class 2.5 cm3 designed and manufactured in a self-similar laboratory of the Palace of pioneers and schoolchildren of the Pervomaisky district of Moscow under the leadership of A. Pyatibratova. Model — winner of national Championships in 1977-1978. Designed for engine KMD-2,5, diameter of wheels 80 mm. With properly adjusted and well firmed engine model of this type at speeds of about 170 km/h Special attention during development was paid to reliability of all units.
