AND AGAIN NUTRIT

AND AGAIN NUTRITOn the mechanisms used to its movement due to inertia of the rotating imbalances of the journal “modelist-Konstruktor” wrote more than once (see number 5 and 12 for 1975, No. 6 1976, No. 3, 1978). The publication aroused great interest among readers, so we return to this topic. The amazing ability of nutricola, or inertsioidov, as they are called — to move without using wheels, tracks or air screw — continues to captivate enthusiasts-inventors. And although the effectiveness of this type of propulsion is not yet well-known competitor, perhaps one of the most perfect models of nutriton will be a prototype of the future transport. And while we offer to your attention another scheme inertsioidov mover. Its author — kas reader from the city of Ryazan Alexander Mikhailov.

SUMMER MOTORCYCLE IN THE WINTER – SNOWMOBILE

IN THE SUMMER OF THE MOTORCYCLE IN THE WINTER - SNOWMOBILEIN THE SUMMER OF THE MOTORCYCLE IN THE WINTER - SNOWMOBILEMore widely used today snowmobile technology. Industry and Amateur craftsmen create a wide variety of vehicles specially designed for use in the winter. For now the spring comes, and the powerful “Buran” is sent to the Parking lot to the garage to wait for the next season, and its owner is transplanted to the other “horse”, most often the motorcycle. But would it be useful to have two almost identical vehicles differing only in chassis? Can we make a universal motorcycle-snowmobile?

Indeed, the skateboard was created as a simulator for the skier, but soon became widespread as an independent apparatus. Rolling becomes a sport: many fans began to unite in section at stadiums, various sports clubs.

“AERODZHIP”: FROM DESIGN TO MACHINE

Student design Bureau of the Riga red-banner Institute of civil aviation engineers named Lenin Komsomol familiar to the readers of our magazine. Development of Riga have been exhibited at Central exhibitions NTTM at ENEA USSR. Some of them — the wig and bioacoustics systems, seaplanes and apparatus for measuring motion parameters of aircrafts and trikes for agriculture told “modelist-Konstruktor”.

FOR EVERY TASTE AND AGE!

FOR EVERY TASTE AND AGE!

Cyclist with experience or cyclists are hard to convince that there is a treadle machine better than “Tourist”, “Sports”, “Satellite”. For many years I preferred legkodelimae bike over all the others. However, with the advent of folding machines became obvious advantage during transportation and storage. But, unfortunately, it turned out that the effort that is required to make when moving they are more relevant to bicycles.

GLIDERS OVER THE PANEVEZYS

GLIDERS ON PANEVĖŽYS

Weather did not spoil the young glider pilots. The sky is high and blue, as it often happens in Lithuania at this time of year, gray and low down over the green field airport.
