Design
In the design of the transmission of a snowmobile “Buran” has a centrifugal accelerator, the CVT. During intensive operation of the snowmobile this node will wear out within two seasons. First fail the movable cone of the variator and Cams-weights. The reason for such a rapid wear of the mentioned parts is quite simple: the Cams abut in the troughs of the movable cone, thus squeezing out deep dents. When starting the snowmobile from the place when the engine begins to develop momentum, the Cams are unable to smoothly get out of these depressions, there is a sharp jerk of the belt variator, which leads, among other things, and rapid wear of the belt. In short, almost every season you have to change the movable cone, centrifugal accelerator and a belt.
LITTLE MICRO-CAR “CRAB”
Not for them the track of the reps! Your creative impulse they send, for example for roads technical search. Only what no one else did, and the only way never done before! It is no coincidence that this team such a name: “CLUB ETERNAL SEARCH”! His avtolaboratoriya House of pioneers of Leninsky district of the city of Kharkiv. Interesting and exciting work here with the young designers a big fan of Amateur autostructure, a frequent participant of all-Union rally of home-made machines Valery Taranukha — Manager, mentor, chief designer. It creates the micro cars are always distinguished by originality of design and aesthetic execution.
AT THE START — “PENNANT-9”
Flying clubs Directive of the Central Committee of DOSAAF of may 25, 1979 allowed to build gliders only on the drawings approved by the technical committees of local federations of hang gliding. Besides flying a self-built devices should be performed only after examination by the representatives of the technical commissions in the field. This decision was due to the need to ensure safety both during training and during sports performances and is intended to nullify the persisting injuries.
ANOTHER “POCKET”
Young innovators of the Moscow machine-tool plant named after Sergo Ordzhonikidze developed subminiature winch, dimensions of which (240X215X115 mm) allow to call her “pocket”. With its low weight — a little more than 7 kg, it develops a traction force of up to 1 T.
ON-ROAD AND OFF-ROAD…
Laureate of Lenin Komsomol prize of student scientific-technical society of the Moscow higher technical school named after N. E. Bauman is one of the oldest in the country. Founded in 1903 N. E. Zhukovsky, the NTO over the years of its existence gave the careers of many famous aircraft designers, scientists, inventors. Good memories most of them left their intended course of development of the NTO, areas for further research, which over time has gained followers, United in independent laboratories, student research centers. Thus, in particular, in 1949, in the scientific and technical society has a new creative division of student design Bureau, which from the very first days of its existence began to work closely with the production, scientific-research institutes. With the expansion of subjects, which was engaged by SKB, it created all new laboratory, a new student design teams.
SERIES “P”
“It’s time my childhood fell on the difficult post — war years, begins his letter to the editor M. I. Psarev. Toys we then did ourselves. Apparently, this brought me love design — all my life I’m not breaking up with tools, metal, wood and, of course, pencil and paper. Here came the second half of life, and the desire to rukovodstvu not quenched, but flares up sometimes with such force that you forget about everything”.
FROM “ZAPOROZHETS” — “BUGGY-350”
For many years since the entry into force of “Technical conditions” to build a home-made micro cars and sidecars the creators of these machines in their structures often used the main gear of the rocking rear axle and transmission from a wheelchair sidecars of various modifications. All the disadvantages of these mechanisms are stereotypically repeated in almost every home-made, significantly impairing their performance. Traced the pursuit of more utilitarian to fulfill this part of the design, almost nothing or nothing changing in the factory units, and parts and disguised all this slightly redesigned (compared to wheelchair) the body, fenders and other “decorations”.
ELECTROCUTING TO BE!
Numerous experiments to create a map with the electric drive until now led to the emergence of machines, its high-speed qualities can become a training, not racing. After analyzing design flaws, we tried to create electrocat (Fig. 1). able to become a competitor to the traditional internal combustion engine.
BUER IN A BACKPACK
The beauty of this glider, named “Tetra” (because of the shape of its frame), is that it is collapsible and place of training it is possible to carry in a bag or backpack. It weighs more than 20 kg. Frame glider — tetrahedron, assembled on bolts of duralumin or steel tubes. The mast compound, its elements represent segments of dural pipes with outer Ø 40 mm, stacked with pipe sections of smaller diameter. The lower part of the mast is integral with the frame Buer from the pipe Ø 50 mm.
ELECTRONICLY TAKE A RUN-UP
Autonomous electric vehicle for urban master-lay is born in pain. The searches are in many countries and firms, and individual enthusiasts, yet Balk at the same impasse: power, drive. Design created by analogy with the used in production areas, being “dragged” on the streets, reminiscent of a fish out of water — they also “choke” from lack of electricity, the power required speed. Because the developers have to deal with existing types of batteries, the energy intensity which does not allow to use electric motors, similar in power to the internal combustion engines. Hence, not the same acceleration and ground speed, and the range obtained is very far from desirable.
