Design

In recent years, the aviation enthusiasts in many countries are showing great interest in flying on makeshift gliders-the gyros and the gyros. Inexpensive, easy to manufacture and easy to pilot, these aircraft can be used not only for sports but also as an excellent way to familiarize wide circles of young people with the element of air. Finally, they can be used for communication. In 1920 – 1940th years, gyros were built in many countries. Now they can be seen only in museums: they could not compete with helicopters. However, for sporting purposes the gyros and especially towed gyroplanes-gliders are used in our days (see figure).

The plane “pilgrim” in the Tver club “Aviator” was conceived in 1978. He was born in the debates and discussions. In the end, it was decided to build it in the scheme of “Demoiselle” in flight technology: soft dual wing. The design relied on overloading the +8 and – 3 (destruction). The horizontal tail was taken in the range of 2 – 2.2 MAR. The original wing that the ribs to the spars are fastened, and inserted into laderman fabric covering.

The ATV is made of that which was in the garage. Generally in the construction tried to use as many parts from domestic cars. Yes, and that turning was smaller. Engines with gearbox (welded differential) – from the car “Oka” VAZ-11113. Quad – double. Seat though homemade, but made on the principle of the factory – the passenger sits slightly above the driver, it has the backrest and footrests.

Its high performance is a boat more suited to voyages on inland waters and small weight of the hull allows to deliver it on the upper trunk or the trailer car almost any “blind corner”. Chibis can be recommended to fishermen and campers for offline (up to two weeks) trips of two people or of hikes of the day the three of us. Will like this boat and the villagers standing along the banks of rivers and reservoirs, as an everyday vehicle, the more that the opportunities for installation of outboard motor, sails or oars makes it universal.

This mini tractor was built in a family of Amateur design Bureau of Paul: under the guidance of the head of the family of Valery Vasilyevich machine was assembled by his sons Sergei and Andrei. All three are longtime readers of the magazine “modelist-Konstruktor”. Small-sized tractors, called by its creators the acronym SAP (S. A. Paul), is designed as a universal – tilling and transport agricultural unit. He can plow, cultivate, harrow, and to tow a cart with goods or a small tank with a capacity of about 100 litres for watering the infield.

The idea to build the Rover on low-pressure tires came to us with father after he was unable to rise to the snowmobile “Buran” to “Lunar glade” in Arkhyz. The design of the machine — type buggy, double, all-wheel drive. Frame — spatial with arc security, welded from tubes. Both the leading axle — back cars. Front axle is rigidly attached to the frame, and the suspension of the wheels — independent, transverse A-arm with clinohedrite dampers. Torque from the axle shafts is delivered to the wheels via CV joints. Rear suspension — dependent. Rear axle and its axle shaft just lengthened (track greater than 2 m). To the frame it is attached to the trailing arm with spring-hydraulic shock absorbers. Base — 2600 mm.

It seems incredible that sparkling chrome valarelli, one of the many exhibits Central exhibition HTTM-82, manufactured by teenagers — it is very “factory” looking. And still made him the club Tashkent city station of young technicians Abdukhamid Dechomai and Hassan Nurmatov. Directed by designer-designer V. A. Ashkin. Vladimir has developed a series of modifications of teenage roller. To build the most interesting of them, he decided with his young assistants. The first was valarelli. About how it works, says the designer himself.
