WALKING RECUMBENT

Categories Design

RECREATIONAL RECUMBENTOne of the main sources of environmental pollution is the vehicles. Therefore, constructors have a natural desire to create alternative, environmentally friendly means of transportation, which fully applies and recumbent. As the basis of its development, we adopted the design of the velomobile V. Mazurchak (“modelist-Konstruktor” No. 10 of 1987). But the technical capabilities are not allowed to repeat the machine one to one, we are particular to this and not sought. Besides, from the point of view of “strength scientists”, analog velomobile is, in our opinion, not very successful scheme of loading the important elements: the junction of the front and rear parts of the frame and the axis of the rear wheels, which can cause breakage of parts or assemblies during operation. But I wanted to make the car reliable (and therefore is durable) and thus to meet at least 20 kg of weight. The velomobile was to have such dimensions that enable it to pass under a standard door of the apartment and fit in a regular (not cargo) lift. Well, that was easy to transport and store, wanted to make it more collapsible.

UNMATCHED AVIATION

UNMATCHED AVIATIONToday we continue the theme begun with the publication of non-traditional polyopia supersonic fighter-interceptor MiG-25, the New development even more unusual in the choice of the prototype for the copy and overall design of the model. Today, it is about the reproduction in miniature of a legendary airplane “Voyager”, made in 1986 by flying non-stop around the globe. I hope that ego of publications will contribute to the revival of some extinct interest to the class “school” sports polycopy. It should again be noted that Voyager, like the MiG-25, only a single instance of a large number of interesting prototypes, giving modelistica up at any level.

MANAGEMENT OF GAS — ON THE RADIO

MANAGEMENT

There is a perception that control the “gas” compression of the motor as well as nitro, is almost impossible. However, for a long time had already been quite successful systems for remote control of frequency of rotation of the shaft diesel. Failure, usually associated with the specificity of modes of diesel and errors in the design of standard mass carburetors of the motors. Such subtleties on the proposed material, telling about the alteration of the compression of the engine under remote control.

MINI-GALLEY OF THE BOAT

In a small cabin boats and yachts on the account each square decimeter square. To allocate a special space under the galley is a problem. Therefore, for cooking every time it is necessary to approach the shore, and the command is placed directly on the grass-field. In addition, you have to lug the dishes and supplies, something forgetting, annoyed and irritated. Especially if it’s raining or late with the choice of place for sleeping. However, for owners of vessels close to the dimensions of 2×5 m, the situation with the galley not hopeless, if the cabin to find a secluded area and attach the hands. An example might be the experience of a rational use of the area in the interior of our planing of the vehicle “Triton” (“modelist-Konstruktor” No. 5 of 1996).

Someone had to ride on a sled, knows that the particular manoeuvrability from them should not wait: in the best case they can be deployed on a steep slope, but changing the direction of movement of the sled is not easy. Meanwhile, the sportsman-the mountain skier could turn with ease. And the reason that skier unlike the Luger can tilt the skis: relying on steel edges, they can easily enter the curve, allowing the athlete to move on their chosen path.

GRANDPA'S INHERITANCE

Is made whether furniture or other woodwork — home of the wizard there is a desire to decorate their curly reliefs, patch convex pattern… Here it would be bailed out lathe. But the store to buy today is expensive. Do it yourself is another matter. The Bulgarian magazine “Young designer” offers to remember the simplest design, which was used by our grandfathers. It is attractive because it is available in the manufacture of almost everyone, has no complicated components and does not require any scarce materials. As possible, despite the “old days”, is no worse than any of the purchase options: after all, fine examples of folk art, which we admire in the local history and ethnographic museums were created about the same machines.
