Electrofresh is intended for soil (top soil) household and cottage (with electricity) sites, hilling potatoes. Considering the rather difficult conditions: long continuous work, continuous overload, dust, preference was given to more severe and large industrial three-phase motor is totally enclosed, front manifold, DC.
TO THE TRACTOR… ON THE TRACTOR
Mechanic Valery Kirilo from the village N. Chernychova the Brest region, built the Rover “KV-4” — jeep, which can work as a wheeled tractor. As a motor it has an engine “PD-10U”.
The creation of RC model aircraft preceded, as a rule, the search of the prototype aircraft, because aviation hobby in the first place, is a small picture of the real aircraft. As for the “Finist”, selected as a sample when designing a radio-controlled model, he seemed to be specially created by the designer as a future prototype flying polyopia. In favor of this choice — and the wing of large aspect ratio, and developed a stabilizer, and a rather large keel, and a voluminous fuselage, makes it easy to install control equipment model.
In the fourth issue of our magazine published model glider of the world champion V. Extencive. Today we offer timesnow model champion of the USSR E. Verbitsky. She applied some new technical solutions, providing the model a clear advantage at the USSR championship of 1973. Especially clearly its benefits manifested in the last, tenth round of the championship of the USSR.
Many model aircraft model equipped with a well-established micro “Rhythm”. However, those who uses it on models-copies or RC, you know that this engine is impossible when you run the game change the speed. This can be achieved only with the improvement of the carb by creating additional devices to measure the flow of the fuel-air mixture.
Few, probably, ever see a modern sailing ship. It is widely believed that in our age of powerful engines and high speeds boat the best place in sports or for training cadets of sea schools.
Under the terms of the competition model rockets must stay in the air for Some time, and it makes rocketmodeler to look for different Methods of forced landing. Very interesting designed and a mug of rocket and space modeling the pioneers of the town of Krasnozavodsk. It allows you to limit the time of flight depending on the conditions of the competition.
Historians say that the sail appeared on land about four thousand years ago! Fiction? No – there is documentary evidence. In 1953 the Italian archaeological expedition at the excavations of the temple of Ptolemy near the town of Medinet MADI discovered the remains of the ancient land of the sailing ship. Designed and manufactured it was under the leadership of the Egyptian Pharaoh Amenemhet III (1849 – 1801 BC). It was a rook, which floated on the Nile at first, and then mounted on four wooden wheels. Two four-meter mast stretched colored sails. The inscription found in the desert of basalt polished slab read: “Pharaoh Amenemhet III traveled from here across the desert to Medinet in a sailing boat driven by the wind.”
A distinctive feature of this model of rocket plane is turning the wing. It is set along the fuselage, which eliminates any possibility of the appearance of the spiral during takeoff.
