Any machine is not born suddenly starts with something more simple. It happened with the plane-monoplane. Its forerunner was destined to become a flying model. Was 1887. Professor of physics and astronomy, scientific Secretary of the Smithsonian scientific Institute of Washington Samuel Pierpont Langley was seriously interested in issues of flying heavier than air. Having done a series of aerodynamic experiments to test model wings for vertical installation — “revolving machine” Langley was engaged in the construction of flying models. But first, he carefully studied everything that was already reached before him, in particular flying models are heavier than air, which were built in 70-ies in France. At that time the greatest success in model experiments reached the Frenchman Alphonse Peno, first to use rubber motor for rotating the propeller of a model aircraft, and Austrian Wilhelm Kress.ABOUT HOW MODEL AIRCRAFT DID

The design — motorcycle, half-track course with the steering front wheel with a tire of low pressure and driven by caterpillar designed to be driven on the road, mainly in the summer and in the offseason, in the winter in the snow (snow cover 25 cm), as well as on ice and crust. The permeability of the motorcycle, in principle, “everywhere.” The only exceptions are water obstacles to a depth of over 30 cm (floods the ignition system) but the swamp where the man gets bogged down knee-deep On a motorcycle can carry cargo up to 30 kg, and the trailer under 80 kg in the summer — on the wheel (high flotation tires), winter — sledding.
In recent times in the aviation modeling is increasingly being used by electric motors. This is understandable, their advantage in comparison with internal combustion engines is obvious: easy launch, precise control of the screw rotation speed, no exhaust, low noise.
On 37-th Moscow city competition of young men in the micro models, held at the tennis court “Dynamo”, the attention of fans and athletes drew suddenly appeared in the air brightly colored model airplane. She almost silently circled the ceiling of the court, and after a minute or two gently landed. On refilling the tank and running the engine only took 30 seconds and was again in flight. This model installed on the original engine it says the author is the head of the aircraft modeling lab of the Moscow House of young technicians of a name of P. I. Baranov master of sports I. SHKALIKOV.
How to be autoconstruction mug? What it should build cars? How to organize classes? These and many other questions were raised in the recent publications of M. Larkin, and L. I. F. Rychkova “Project — model — car” and “car Designer — car designer!” (“M-K” № 1, 1979). More of our readers interested in the technical side of things — the device is modular inputs to directly affect. Today we offer the latest development autoconstructor laboratory Cut of the Siberian branch of the USSR Academy of Sciences — the micro-car, only “Protein”.
Successfully participated in Izhevsk in the Russian tournaments (1978) on experimental models of type “a flying wing” command of Leningrad. All the participants become
Easy to manufacture, high speed and high manoeuvrability are the main qualities of this model. It fully meets modern style of air combat. The Antonov an average skill can make it ten days. The greatest investment of time will require the fuselage. First saw mount made of plywood 10 mm thick, then cut in the end: glue the pine strips of appropriate length, cross-section 10X3 mm. In the rear edge of the wing and stabilizer put the glue on the fake insert. The interval from the motor to the first insertion complete the rigid foam and the tail boom braces reinforce the phony. Outside (to the side surfaces of the slats) glue fake veneer.
In aeromodelling clubs of the pioneer of the Kominternovsky area, obsut and Kharkiv high school № 112 in a few years, work is underway on the co-axial model helicopters. Their designs are different, but they steadily fly. The following model is one of the latest versions. In the competition “Experiment 78” in the class of timed models of helicopters, she won first place.
This little torpedo boat continues a series of models for competitions. The model is simple to manufacture and has good driving characteristics.
In our home the garage there is a well-worn snowmobile “Buran”. I’m not going to Express their attitude to it in General, because the views of the owners on this issue diverge. However, the work of his heart — the motor always caused not only anxiety, but also from year to year required surgery. Every summer, making these “sleighs” for the winter season, in the engine due to wear and something changed: the rings, liners, pistons.
