With the end of the Civil war in Russia and the formation of the Soviet Union began intensive development of commercial aviation. July 15, 1923, opened the first regular air line Moscow – Nizhny Novgorod. For three and a half months by air it was transported by 270 people. In the following year there was a line Odessa – Kharkov, Moscow – Kharkov, and others. The development of Civil aviation is objectively required the creation of a passenger aircraft. One of the developers of passenger “air carriers” was the aircraft factory No. 1, former “Dux”, where in 1925, the engineering team headed by H. H. Polikarpov, and A. A. Semenov established a five-plane PM-1.

This machine is not only powerful and roomy I was able to fairly compactly arrange all of its aggregates, making the frame left plenty of room for the passengers and even any cargo, including bulk or lengthy — it is a body of 250 kg, the trailer for 1 ton and wheeled console.
The idea of creating our “Donkey” arose almost by accident. Once the chefs gave us a written off motorcycle To the 125 without wheels. Original spare wheels we had, we decided on the first case to fit available handy motorolleri — with hubs and discs from the T-200.
Existing models of walkers have several major disadvantages: the speed of these machines is usually not more than 8-10 km/h; they move irregularly or are experiencing vibrations in the vertical plane; walking mechanisms are mutually unstable.
With the proposal of developing a new Intercontinental ballistic missile operating on liquid oxygen and kerosene, and in 1958 was made by the Council of Chief designers. While its weight was not to exceed 100 tons, which is almost three times less than the starting mass of the rocket R-7 – the famous “seven”.
Little micro-car “Buddy” machine… for kids. It was created in a laboratory experimental simulation and design Club for young technicians Novosibirsk Akademgorodok. Despite its small size, it all like a real car: engine, transmission, driveshaft, closed rear axle with a differential and other components.
Such a transformation that my construction readily admits. Moreover, the possibility of replacement ski floats, making it easy to turn a land car in “waterfowl”. Flat “breaking” the frame of the snowmobile hromansilevyh welded from pipes. The front part is a double cabin crew back — powerplant based on the engine of the motorcycle “Dnepr”. The cabin has a roll cage and aluminum siding.
The individual system are two dorsal scuba gear of any type. The main materials are fiberglass and aluminum alloys. Widely used aluminum alloy D16, soft, seasoned, in the form of plates and moulded profiles. Made from this material stringers, beams, frames, individual components and subassemblies. Was also used steel of different brands, it made small parts and fasteners. For the glazing of the cabin applied in organic glass. Insulating and sealing elements made from PTFE and rubber of different brands. As the filler has been widely used foam stamps “PS-4”.
We offer parachute system for more than three years is used by Leningrad on models-copies of carrier rockets of space vehicles. Simplicity and reliability has contributed to our athletic victories. At the last all-Union competitions in Smolensk in 1971, this parachute system was equipped with our model-copies of spacecraft “Soyuz” in grades “K-3” and “K-4”.
The plane “quantum” is a single, freely carrying an all-metal monoplane with a low wing, having a trapezoidal shape in plan, with the influx of the leading edge at the side of the fuselage. The empennage is a cantilever, the normal scheme.
