Dvuhdverny aircraft-su-25 attack aircraft designed for direct support of troops in local conflicts under conditions of strong counteraction of the enemy air defenses. The development the design Bureau of P. O. Sukhoi began in 1968, the First flight of the aircraft. piloted by test pilot V. Ilyushin, was held on 22 February 1975 and the following year started its serial production. The first experience of combat use of the su-25 was obtained in April 1980 in Afghanistan. Subsequently, the plane was used during the suppression of the rebels in Chechnya and armed conflict in the former Soviet republics. Was exported to many foreign countries. On the basis of the airframe of the su-25 created a number of modifications, including the training of the su-25УТ, carrier-based su-25UTG, and su-25ТК. Subsequently, the su-25 came the su-39, which, in turn, served as the basis for the creation of new modifications, more fully meet modern warfare.

The main ships of the U.S. Navy aircraft carriers are always ready not only to strike at the enemy, but also to reflect the Vietnam War revealed the limited capabilities of us carrier-based fighters for the conquest of the air. Assessing the first results, the management of the fleet air arm in 1965 has supported research of the company “Grumman” on the program of creating a multi-purpose carrier-based fighter and, having their priorities in this program, in July 1968, officially declared the competition for carrier-based fighter-interceptor VFX (Variable Geometry Fighter Experimental). Their proposals presented to the company “Grumman”, the “North American”. “McDonnell-Douglas, General dynamics and Ling-Temko-out”.
Born of fire. As it is impossible to imagine a good porridge without butter, and high-quality mortar without lime. It’s a common binder finds wide application in construction. Lime is produced by calcination of sedimentary rocks, the main component of which is calcium carbonate and perhaps magnesium oxide, When the content of magnesium oxide more than 7% of lime is called magnesia, with a smaller it presence of calcium. In the construction using both lime. These rocks are tight, clean and dolomitized limestone, chalk, shell limestone and other Rocks should not contain more than 8% clay impurities (the fewer the better and cleaner lime). Roasting is performed at a temperature of 900° — 1200°C up to possible the complete removal of carbon dioxide, that is, the decomposition of calcium carbonate with the release of carbon dioxide and formation of calcium oxide or so-called lime-quicklime.

Since then, he’s on different models with a muscular drive of his own, passed under the Russian and foreign roads the way, almost equal to the equator of the Earth.
In the design of the transmission of a snowmobile “Buran” has a centrifugal accelerator, the CVT. During intensive operation of the snowmobile this node will wear out within two seasons. First fail the movable cone of the variator and Cams-weights. The reason for such a rapid wear of the mentioned parts is quite simple: the Cams abut in the troughs of the movable cone, thus squeezing out deep dents. When starting the snowmobile from the place when the engine begins to develop momentum, the Cams are unable to smoothly get out of these depressions, there is a sharp jerk of the belt variator, which leads, among other things, and rapid wear of the belt. In short, almost every season you have to change the movable cone, centrifugal accelerator and a belt.
I want to share with the readers one very simple method of drilling holes in the glass, which I was taught many years ago Professor N. A. Artemyev. The method is attractive because it does not require special machines, at the same time allowing you to drill glass of almost any thickness. The edge of the hole can be as close to the edge of the glass; the method also allows to cut out rings and circles of different diameter.
