German Aircraft

In March 1940, A. Antonov, who worked at the factory number 23 in Leningrad, was charged with developing an analogue of the German light aircraft Fizeler Fi.156. Working on the analog, which received the designation "aircraft number 2" (EYE-38), Antonov proposed a on the basis of its military cargo "plane number 4," distinguishing features of which were radial engine M-62 light fuselage and biplane cellule. Then rejected the idea of military aircraft, biplanes, but after the war Antonov returned to it again. In 1945, the OK Antonov, the deputy chief designer of OKB-115, addressed the Yakovlev aircraft design with a proposal of his own design and received his consent. The project "aircraft 4 "has been completely redesigned.

From the previous project there was only a biplane box. In March 1946, the Novosibirsk branch of OKB-115 was transformed into an independent OKB-153. Its chief designer was appointed Oleg Antonov. Main task was to develop new CB transport aircraft "T" with a motor-62IR. Developed in parallel with the agricultural version of the engine AL-21. The first prototype, designated Cxa, was built in 1947. August 31, 1947 test pilot AP Volodin first raised it in the sky. In December, the Air Force Institute began its state tests, which lasted until March 1948.

In July of that year resulted in testing a second prototype with the engine AL-21. 23 August 1948 under the designation of plane An-2 was adopted by the Air Force and for the supply of CAF. Mass production was organized at the factory number 473 in Kiev.

Russia System

Obtained a closed ring – explains Anton Belov, deputy director of thermal automatics "Danfoss", the world's largest manufacturer of energy efficient equipment for heating systems. In twin-circuit heating cottage heaters in parallel. There are two pipelines that were not originally closed to each other. One (direct) heated coolant is fed into the system from the boiler, the second (Reverse) cooled coolant from the system goes into the pot. Follow others, such as Chuck Berry, and add to your knowledge base. Of straight pipe in the back water flows through the radiators. " The advantages of single-pipe heating system may include a relatively simple installation, less than the total length of pipelines, less complicated configuration and, consequently, a lower cost budget.

If the cottage floor, has a small area (around 100 m2) and the heating system does not provide any equipment, than the actual radiators (eg, heated floors, etc.), then we can focus on this version. If the cottage is more than one floor, a large enough area (as in Russia today is an average of 300-400 m2) and a complex layout with the premises, requiring the use of heating devices of various types, the Single-pipe heating system for a private home is unlikely to be a good solution. Why is a large private house better system two-pipe heating system? Firstly, because the heaters in the heating system in series, then each additional water enters, already having given a certain amount of heat above. That is the first sink in the chain is always the hottest, and the last – the coolest of them all.

Moscow State University

By conversion into electric variables by means of transducers can be measured by electrical methods. Great value instrumentation for scientific research. Their development can carry out complex physical experiments lead to new scientific discoveries. Currently, no quality of electrical instruments and devices can not conduct research to date, the development and introduction of electronic computers, automatic control and management. Word of the Mendeleyev that Science starts with since starting to measure, and that an exact science is inconceivable without measures supported by the entire history of the art of electrical measurements. Its emergence in the mid-XVIII century.

When in 1745, Acad. GV Rihmanom, ally Moscow State University, created the world's first electrical measuring instrument, called the author of "The measure of electrical force." It was the electrometer, which was used in the study of atmospheric electricity and possible to measure the potential difference. However, further development of the electro received only much later, it was associated with the transition from qualitative observations of electric and magnetic phenomena to establish quantitative relationships. Only in the second half of XIX century. Suddenly we needed to develop devices for measuring electrical current, voltage and resistance. By this time, were created and began to find practical application of electric power generators, and the lack of instrumentation hampered the further development of the emerging electronics. For example, the first experiments with electric shocks have revealed heating conductor (Petrov, Deve), but the lack of accuracy not possible to find the exact quantitative relationships. This could be done only later, Joel and Land (1841).

Certificate CNG

MV Frunze. Company of PEC "Sumygazmash" Fifteen years is a serial manufacturer of CNG filling stations, CNG, CNG-gazorazdatochnyh columns 1, CNG-2 and other gas-powered equipment. The company is located in Sumy, today the company employs staff of 300 employees. Integration of equipment allows you to create gas stations with capacity from 40 to 1,000 or more fillings per day. Factory quality system complies with international standard ISO 9001:2000.

AGNK equipment certified in Ukraine (Certificate of Compliance UkrSEPRO UA 1.036.0034184-01) All CNG stations have Certificate of the Russian Federation ROSS UA.A45. VO1387 and resolution the application, issued by the federal supervision of the mining industry of Russia RRS 02 – 8033. NGV filling stations for many years successfully operated on the territory of Ukraine, Russia, Uzbekistan, Tajikistan, Georgia and Moldova. All models of CNG stations, manufactured by companies that are designed to fuel cars, buses, special vehicles and agricultural equipment with compressed natural gas (methane). Gas through CNG is a complicated technological process and compressed to a pressure of 22-25 psi (220-250 kg/cm2), and then injected into the cylinders as motor vehicle fuel, ready to use. In contrast to the large NGV filling stations of the station is easily located on a small area near the road or the fleet. Gas is consumed in urban gas supply, and of the main pipelines.

In addition, CNG can be installed at gas stations, local, in the wells for the extraction of methane, as well as installed on the oil wells with associated methane. Mounting of the station you must install the equipment CNG to prepared foundations and make a connection to the gas and electricity network. Water for technological purposes is not applicable. Heating in the technological blocks are not required. CNG stations operate in automatic and semiautomatic modes. Automatic system controls the parameters of the station, switch on and off, as well as automatic shut-off station at output parameters exceed the limits. "Firm" Servisgaz "Evpatoria for the period from 1997 to 2005, has commissioned more than 60 CNG filling stations in Ukraine, releasing with 120 units of compressor units. Main production site was "Evpatoria experimental mechanical plant with a production area of 7,000 m2 and a staff strength of 250. In order to expand production and improve technical performance The brand "Servisgaz" acquired a controlling stake in Simferopol Machinery Plant "Progress" and set up a joint venture with Ural Compressor Plant – OOO NPF "Servisgaz." Today OOO "NPF" Servisgaz "supplies the following equipment for CNG filling stations under the brand name" SKIF : 1. Compressor units with a low inlet pressure of GS-2, 3 / 400, NH-3, 7 / 200, HS-4, 2/200G; ami-5, 1 / 250. 2. Compressor units with a high input pressure AGSH-8/4-250; AGSH-9/7-250: AGSH-10/13-250. 3. Device for filling car with gas methane RAG-20. 4. Column for the refueling of cars with methane gas, SCG-1. 5. Batteries gas KD-700. 6. Unit of gas dehydration. The largest manufacturer of automotive filling stations in Ukraine is also of Sumy. MV Frunze. Typically, the full range of CNG implementation: design, equipment supply, installation, training specialists, sales service and repairs performed manufacturers and suppliers of CNG filling stations. They will help you in carrying out feasibility studies for implementation such equipment, so that your business has been profitable.
