Unlike analog, in the boat “Victoria” from St. Petersburg to create an air cushion and propulsive forces (thrust) uses an air screw. This allows the machine to move using both static and dynamic air cushion. The transition from mode to mode is performed by changing speeds.WHEN WE RAN OUT OF SHAMPOO
You have repeatedly placed the tips where can I find the use of plastic containers of shampoo. I don’t throw it away. Those that phobophile diameter, use as holders for rolls of paper, drawings. If a plastic glass tight to insert (with spacers) glass vial — he will attain sufficient impact resistance. A ring cut Read more…
The search for the optimal design of passenger car is a matter of time. The solution to this problem and doing powerful design Bureau leading automotive companies and associations, and Amateur designers. Our magazine has repeatedly appealed to the topic. Today we offer enthusiasts autocostruzione two promising development of the Moscow engineers P. Zak and E. Rudyk.
Recalling the history of the snowmobile, realized how long ago began my fascination with construction equipment. Even in his youth (and now I’m already retired) received the specialty of a locksmith and mastered on his own welding business, other specialty Metalworkers. But knowledge of design, to tell the truth, “boast” could not, and to learn there was no place. Built on a whim any “grindaholik” on wheels and tracks went on them and on the road and in the snow, but neither the reliability nor beauty.
Now suburban suburban areas are very popular green lawns, pleasing to the eye a beautiful grassy carpet. However, they require proper care and maintenance, the complexity is almost equal garden chores: the lawn need mowing, watering, update affected the economic activities of the place.
It is impossible not to admire the rapid slide on the water surface caught wind of the windsurfer, or at least a dizzying descent from the rampant ocean waves athlete on the other Board, resembling a wide ski. Both of the sports projectile at a fairly thin shell of the hull have a fairly soft filling of foam, so damage to this boat is worth nothing — even enough it doesn’t blow. However, to plug the “hole” so, as advised by the Hungarian magazine”, Earmaster”, is not particularly difficult. The proposed method is also interesting because it can be applied in other similar cases, and similar structures.
After a few years of correct operation your drill is the drill started to “MOPE” – ends quickly charge the battery (battery), has to be frequently charged, and for this to interrupt your work. Losing battery capacity is inevitable with heavy use (depends on the amount of discharges-charges) and over time. By the way, if the drill is rarely used, the battery capacity is also reduced by itself (especially if it is stored uncharged), and a year later, may be reduced by a quarter or more. But in many cases, this occurs prematurely because battery other dangers face. So, it will inevitably deteriorate if you apply the tool when the ambient temperature is below 0°C and above +50 °C and in rainy weather and damp conditions, especially if spilled into the water.
From the history of the tram car. The fact that on the tram lines of the country “standard” rolling stock occupied by the end of 1930-ies a dominant position, does not mean that he was free of flaws even for its time. First and foremost, experts have noted excessively large (14.5 tons) mass of motor cars of type “X”, which, being generally crowded with passengers, caused increased consumption of electricity. This dramatically inferior in dynamic characteristics surrounding them more intense flow of road transport, loud and unpleasant noise when driving, and quickly destroyed the railway track already laid in most of cities, buildings, that is, on the live thread. The elimination of the second control stations and door openings of the left side eased “Kharkiv” rather little, as it simultaneously had to introduce pneumatic actuator doors, the driver’s cabin and other improvements dictated by concern for safety.
