By the mid 80-ies of XX century, the naval experts of the countries of the West had no doubt that the most advanced class of surface ships in the foreseeable future will remain the frigates. These versatile ships-rocket carriers have been very numerous in the seas and oceans under the flags of different countries at the time, swam at least 350 frigates, and their “population” continued to rise steadily. They actually replaced the cruisers and destroyers in most countries of the world, becoming the largest combat units in their fleets. Of course, the attitude towards them has changed: the design and construction of the frigate now began to approach more carefully, trying to avoid the rush and the use of untested solutions.

The name of the athlete rakatomalala Igor Ponomarev, that is, “hearing” and “rocket scientists” and, hopefully, our readers. His technical model development are of genuine interest. For the very same designer search new is the way of athletic perfection, which is especially important for the future of aeronautical engineer (today Igor is a student of Moscow aviation Institute). I guess this is a good example for our young readers.
More precisely, one (50 or 65 watts), operating in three modes. Design advantages: constant availability, visual inspection of the three modes, etc. All provide automation. Power consumption in the idle — 15 watts (on L2), in the normal operating — 45 W (L2 and L3), and overheating — 50 W (L3). Changing modes 2 and 3 is made by the switch B1, in standby mode, by overlapping the luminous flux from L1 to K3 with the handle of the soldering iron.
Many of us love tinkering with their hands various things. But few dare to really costly, complex and lengthy projects. Present to your attention a development tank, a helicopter, a submarine and a roller coaster built by lone on pure enthusiasm. And you weak?
(The story of one of the invention). Red cat almost ate squarecat. She climbed to the skvorechnya and wanted a paw to climb inside. Well, we Petka noticed!
The period between the two world wars represents a considerable interest to historians of technology, and first equipment of aviation. The aircraft of this time, the construction of which has absorbed the existing scientific, technical and technological achievements, remained nevertheless the bearers of the greatest characteristics of the airplanes of the First world war.
