Advantages of compact folding boats is obvious, disadvantages is also. In one of the old issues of the journal “modelist-Konstruktor” (on last page) photos and a brief description of a folding trimaran Leningrad shipbuilding V. A. Vakulenko. His trimaran consisted of three folding units in a triangle and connected in a single whole lattice platform. The great thing about this design is the extreme simplicity of the housings. This is the basis of my boats.It consists of four identical folding compartments. Their side opened and fixed in this position by the spacer in plan resemble a diamond. At the same time, the underwater portions of the compartments have smooth streamlined contours. Sealed jar and two bracing bays to form a trimaran.
In the beginning 1960-ies to the leadership of the British Navy faced the problem of replacement fighter aircraft “sea vixen” (Sea Vixen) more modern machine. First, the sailors wanted to buy from your company “Hawker Siddle” (Hawker Siddeley) supersonic aircraft vertical takeoff R. 1154. But because of its high cost and the inevitability of problems in development, they turned their attention to the American Phantom, which was relatively cheaper and did not require a large investment of time to create.
When winter comes and the snow is “fluffy blanket” covers the ground in many areas, the only vehicle able to overcome it “fluffy blanket”, it becomes tracked all-terrain vehicle or, more commonly, a tractor with a sled-scraper. Of course, you can buy a Japanese ski-goose-nicou Yamaha (though it is worth more than another car) or buy now rare a cheap domestic “Buran”. However, always need such a powerful machine?
Sail is one of the oldest inventions of mankind, who played a revolutionary role in the development of navigation. The Millennium operation has made sailing propulsion is very perfect, and it seemed that his aerodynamic abilities reached its practical and theoretical limit. A new stage of development of this propulsion system uses the wind power, was the creation of a rigid sail with double-sided sheathing.
Beginners only pilots first, as a rule, “fly” for simple models, is designed for small “cubic capacity” of the engine. They learn to manage to work out a complex aerobatic figures. Over time, performance of simple models no longer satisfy them. There is a desire to build a more serious and heavier the aircraft under the engine more “cubing”. And this is not surprising because in such a model, the flight characteristics much better.
Model glider, which we would like to tell the readers of the magazine, was built of the most simple and cheap materials. I think that its design will be of interest to novice modelers. After all, despite any economic problems, the fascination of students with model airplanes has not waned, and only the lack of materials needed to make models that can reduce infantile interest in it.Our model of a glider was built and tested in the fall of 1998. It is easy to manufacture, easy to debug, and makes a beautiful long flights. Well, it can be done not only in the aeromodelling circle, but also at home.
Aim to make brisk, reliable and compact tillers. This mechanical helper and was gardening, and the garden is plowed, and beds cut, and the potatoes on the home field were planted, and seedlings are weeded, and the crop was removed… And most importantly, to run this technique, sitting in a comfortable chair and never feel tired. Not to say that once, but the idea was a success. For three years my homemade motor-block (MB) is, as they say, faith and truth. I called it “Pony.” For endurance, reliability. The only thing he requires is gasoline.
