A few years ago I built my children a little micro-car. Called him “mouse”. Readers of “Modeller-designer” know him for publication in the June issue of the journal for 1980.
We offer our readers a model class S4B (raketoplan) designed by the famous Soviet athlete A. by Karapinar common aerodynamic configuration “duck”. She translates from planning mode to parauterine (forced landing) due to the deviation partneremployees stabilizer in the vertical position.
Grind on a hand grater even a dozen carrots – consuming affair, and if you want to prepare food for Pets to shred large quantities of vegetables, fruits? I came out with a simple electric grater. Used motor power of about 200 watts, with a rated shaft speed of 1400 rpm. (it will fit the engine from a household bench grinder; can be used three-phase asynchronous capacitor switching circuit in a single phase network.)
In one of the competitions for the creation of small agricultural machinery, announced by the Central Committee of the Dimitrov young Communist League and the newspaper “Guide yourself”, great interest was aroused by the walk-behind disc cultivator. The unit in question, universal. In the figures it is visible, what with the changeable work organs it is equipped with. With this machine you can perform the following operations tillage: plowing (with additional weight hanging from the front, chain and grousers mounted on wheels), milling, ridging, disk processing. Plus the transportation of different loads in the towed truck.
Exactly the same as a modern car, soft suspension is needed and its radio-controlled models-copies. After all, the impact of the model on the ground or, conversely, jump over a depression in the road surface lead to vertical oscillations of the wheels of the car that is transferred to the axles and the body. Hard suspension a strong impact on the wheel during motion leads to a separation from the road the entire model. To avoid this soft suspension allows the wheel.
Hang gliding in the 70-ies experiencing a period of rapid development in a short time became a popular sport. The secret of success is primarily due to the simplicity of design and unique performance characteristics of the aircraft. Less than a decade it took to hang gliding to become an Olympic sport. And the desire of athletes to expand the capabilities of the glider due to the start with a flat terrain and climb in the absence of ascending currents has led to that began to appear on the gliders equipped with engines.
Weather service uses a variety of research methods. One of them is the distribution of atmospheric parameters on height. To quickly solve this problem scientists helps small uncontrollable meteorological rocket MMR-06 with solid engine. The maximum height of ascent is 60 km; the instrument complex allows to measure the temperature and pressure of the air to determine the wind velocity vector. Information transfer to the ground by the telemetry system.
X all-Union week of science, technology and production for children and youth, held in January 1983 in the Uzbek capital, has raised a lot of interesting developments from many cities of the Soviet Union. Including all the way from Tashkent. Specialists, participants and guests of the week were memorable examples of vehicle technology, presented the laboratory “Avtokonstruktor” Tashkent gorsyut. In particular, the moped “the cotton-grower-S-83”, intended for people in rural areas.
Walk-behind self-built eager to make the most versatile. This is understandable: it has to perform a variety of agricultural operations. However, to create a design that is most optimal for any work at the farm, is not easy. So, powerful, heavy duty motor-plow, as a rule, is too broad and clumsy in the aisle, and brisk the tiller can’t beat plowing the dense earth. One solution to this problem is offering our reader from Krasnodar territory Vladimir Yakovlev. Its compact one-wheeled tillers will assist in the processing of the beds, will not damage plants close together and, if necessary, in just 10 minutes will turn into two-wheeled motor-plow.
We present rocketmodeler development contains many non-traditional solutions. I hope that they will interest the creators of “microcosmic” technology of today and will be useful to those designing models for the future sports season.
