The Soviet designers managed to create a fighting self-propelled installation SU-85 with a full booking, able to deal with medium and heavy enemy tanks with high maneuverability and passability. Offices and engine and transmission were the same as the T-34 tank. This allowed us to complete the crew without retraining. Unitary munitions and gave an opportunity to reduce its numbers to four, which made a more concerted actions of the crew in battle.BRACE — FOR HALF AN HOUR
Not so rare situation when you urgently have to drill a hole in the tree and drill is not at hand. It is not necessary to ring round friends in the search for the appropriate tool — in just half an hour you can make a brace that will serve you for many years. To Read more…
The model, which will be discussed in this article warmed the soul to generations of young sailors. In the distant postwar years, and even in the sixties, such a boat could be found on store shelves. From many toy counterparts his distinguished acting steam engine in the bilge – in the furnace was burning real flame to heat up and boil water in a small steam boiler, humming quietly, pushing the boat forward, two small jet of thin tubes. On a boat it was impossible to look without admiration – he was so real! And easy the soot from the burnt fuel on the surface of the cutting gave this amazing little machine is truly a “combat” look. The greatest effect was achieved in the twilight, when at full speed in the Windows of the wheelhouse, it was possible to observe the flickering glare of the flame.
Motorists made electronic blocks of ignition, as a rule, according to the classical scheme consisting of a high voltage source, a storage capacitor and a thyristor key. However, such devices have several drawbacks. The first of them is low efficiency. Since the charge storage capacity can be likened to the charging of the capacitor through a resistor, the efficiency of the charging circuit does not exceed 50%. So, about half consumed by the power Converter will be allocated in the form of heat” on the transistors. So they need more heat sinks.
Sweden was and remains one of the few countries in the world, able to create a world-class aircraft. Combat aircraft of that Scandinavian countries have always been some kind of “twist”, they should not be confused with similar machines from other countries. In a world quite similar to each other planes, but similar to the Swedish fighter, perhaps, could not be found. The explanation, in my opinion, is simple: since its inception in the late 1930-ies the Swedish aviation industry is not copied already built foreign aircraft, designed and built their own samples. And the fact that in a short time the Scandinavian engineers to develop could not (for example, modern jet engines and electronic equipment) purchased abroad, including a license for their production. The result of this competent technical policy was the fact that in the postwar “jet race” Sweden is practically not inferior to the world’s leading aviation powers, and in some cases even ahead of them.
Shelf I made for my bathroom, not much different from many similar, but due to some features of its design creates the impression that the shelves in the bathroom as it does not exist. The secret is that the size of the mirrored doors is slightly larger than the dimensions of the locker.
