The development of aircraft, initially under the designation C-80 OKB. Sukhoi started at the initiative of M. P. Simonov in the early 1990s in the framework of the conversion of the defense industry. Two years later, finally formed the shape of the aircraft as a high-performance vehicle intended for passenger and cargo transportation on domestic routes and is able to replace the outdated machines of similar purpose. The prototype C-80 with the turbo-propeller engine TVD-1500 was calculated to transport 24 passengers or 2500 kg of cargo. However, the domestic TVD the time is not ripe and had to rely on ST7-9V of the company “General electric” (USA). With them the plane could carry up to 26 passengers or 3,500 kg of cargo.

The one in the house heating stove or fireplace knows that, no matter how ostorozhnichat with the poker hands will still be covered in soot. This will not happen if the poker to put on the moving handle of a metal tube with a length of about 120 mm, is first sawn along it, Read more…
Czechoslovakian Tatra-87. The speed of the first car was small, but it seemed like the drivers exciting. However, over time they got a taste of driving fast and have begun to demand from automotive companies all more than the speed of the machine. Designers have increased the capacity and power of engines, reduced friction loss, improved suspension, but soon realized that there is a physical limit to the growth rate of the car.
The proposed model is a vivid example of technical creativity of Moscow’s leading athletes-taketomo-delicto that three years in a row became Champions of Russia in this category of high-rise models. One of the athletes — M. Stepanov, who won last year. Our story — about the design of his sports equipment.
To create the body of the car, aircraft or boat, as you know, very advanced technology is Vileika of fiberglass using as a binder a polymer resin — epoxy, polyester and the like. The designer of the model always faces the inevitable choice: which of the options vyklicky to use it? You can select the matrix method of forming, providing a high quality surface without laborious finishing and allowing a “replicate” of the body, which is very useful in the manufacture of models in clubs or circles. However, we have to spend a lot of time on the first production of the master model, and then matrix.
Continue the story of machines and mechanisms, built by V. A. VERBELEN — Amateur designer from the village of Zelenchukskaya, Karachayevo-Cherkess Republic. In the publication “walk-behind — nothing more” (“modelist-Konstruktor” No. 2’98) was described by his faithful gardening assistant “Electronics”. Now we offer you to familiarize yourself with the design of the cargo truck to the tillers.
In recent years, almost all types of modeling in our country is clearly a noticeable trend away from pure sports fields design in the direction of almost amusement equipment. Most obviously this applies to cord classes. Therefore, to force the students to do, for example, high-speed gliders of the group A difficult. Your imprint is applied and undoubtedly changed the psychology of the modern boys and the impact of adequately presented in the catalogs, modelistica stores and in the RC circles, and another that looks more attractive technology.
Hard to believe that everything is created by one person. Besides, not a graduate, but a simple fan design. As for the design and manufacture of completely heterogeneous machines required engineering knowledge in several fields of technology. Plus well equipped workshops and rich material stock.
