Yuzhnoye State Design Office

EXERCISE 1

Read and translate the text using the dictionary. Make up a plan to the content of the text.

Over 35 years Yuzhnoye State Design Office has performed a great number of research and development activities having gained experience in creation of onboard antenna feeders (AF) intended for spacecraft and launch vehicles. High structural reliability of onboard antennas is confirmed by their long-term operation on over 100 domestic satellites including the Intercosmos family. At AF development over 50 proprietary engineering solutions protected by the national patents were applied.

Yuzhnoye State Design Office has wide experience in development of feeder tracts intended for operation as parts of antenna feeders for spacecrafts and launch vehicles. There is a long list of the elements developed: frequency selective devices (filters, diplexers, multiplexers), power dividers (combiners), coaxial and waveguide switches, wide-band waveguiding hermetic junctions, SWF sensors, break-away connectors etc. The elements operate within the frequency range of up to 10 GHz and are structurally implemented on various types of feeder tracts such as coaxial, strip and waveguide. For calculations up-to-date software is used, it enables computer analysis and synthesis of devices designed. The elements have high reliability, small dimensions and low weight. Below is the description of various configurations of antennas and feeder tract SHF-units.

Omnidirectional antennas. For the 0.3-300 Hz frequency band the electric dipole antennas are widely used as omnidirectional. For the lower frequency band section the antenna configuration with retractable electromechanic vibrator gear of up to 25 m long was developed. Self-turning vibrators of up to 8m length are also applied. For the 100-300 MHz band the V-shaped corner antenna configuration is developed$ it is intended for installation on satellite case and unfolding means of reactive elements incorporated into vibrators, dual-frequency antennas with frequency diversion of over 30% are implemented.

Near-omnidirectional antennas. This type antennas form directional pattern with weak directiveness and definite form in semisphere. Antenna configurations provide system operation within P, L, S bands and are installed in AUOS-3, AUOS-C, Sich-1M, Okean, Microsatellite etc.

Waveguide antennas. Wide range of waveguard antennas with various beam shape of directional pattern was developed. They are used directly for SC and LV, as well as irradiators for reflector antennas. A number of complex shape structures (reflector antennas irradiators, subdished) are manufactured using the method of galvanoplastic shaping after the Institute of Technical Mechanics of Academy of Science in the Ukraine.

EXERCISE 4

Read and translate the information about Taganrog radio engineering Institute. Make notes on the following points: location, activities, personnel, facilities, training and achievements

The Department of Antennas and Radio Transmitters (DART) was established in 1954 and attached to Taganrog Radio Engineering Institute on the College of Radio Engineering. It originally called the Department of Antennas and Radio Wave Propagation. Since 1978 to present day it has called the Department of Antennas and Radio Transmitters and for 20 years (to 1998) permanently was headed by Doctor of Science, Professor, the Honoured Scientist of Russian Federation Petrov Boris M.. Yukhanov Yuriy V., Doctor of Science, Professor, has been the department chair from 1998. From the foundation time to 1990 the DART graduated the broad specialists on the specialty "Radio Engineering" of the College of Radio Engineering. Since 1990 the DART has graduated the bachelors of science, masters and specialists (engineers) on the specialty 071500 - Radiophysics and Electronics, since 1993 on the specialty 201100- Radio Communication, Broadcasting and Television and since 2002 on the specialty 201700 - Electronic Warfare Equipment. It also takes part in the training of the specialists on the other radio engineering specialties. The DART has seven educational, two research laboratories and anechoic measuring box of 3 cm and 8 mm microwave ranges equipped with modern radiative, measuring and computer engineering. There are 23 teachers on the DART. All of them have academic degrees and academic statuses: 5 Doctors of Science, Professors. The Dr. of Eng. Sc., Prof. Petrov Boris M. awarded to honorary title the "Honoured Scientist of Russian Federation".

Native citizens study on budgetary  or contract basis, foreign citizens - only on contract basis, or on the interchange.

During its lifetime, the DART trained more then 50 candidates and 5 Dr. of Eng. Sc.

Five monographs were published by the teaching staff of the DART, also more then 1000 scientific papers in different publication, more then 100 inventions and more then 30 reports at the international research conferences and conferences with international participation were made.

Some graduates of the DART at present time are at the eminent leading position, and are gurus, whose major scientific achievements are acknowledged as in Russia and as abroad.

Altitudinal Meteorological Mast (AMM) EXERCISE 1

Read and translate the text with the dictionary.

A unique scientific and technical object of Scientific and Research Institutions of Roshydromet.

Altitudinal Meteorological Mast is supported by the Ministry of Industry, Science and Technologies of the Russian Federation as a unique installation of Russia. The registration number is 0202.

AMM-310 is commissioned in 1959. AMM-310 represents a tubular structure with a height of 310 m and diameter 2,3 m; it is installed on a spherical fulcrum, and is supported in a vertical position with the aid of multi-tier rope system. There is a lift inside a mast for realization of experiments and upkeep of equipment. There are 13 working platforms with four sliding probes with length of 6 m for the arrangement of a measuring apparatus. AMM-310 does not have analogs in Russian Federation and countries of CIS. It is distinguished by equipment and integrated approach in measurement of parameters, including meteorological magnitudes (temperature and humidity of an air, velocity and direction of a wind, pressure), turbulent characteristics, optical performances on sloping lines. The parameters of solar radiation, deposits, clouds and radio-activity of an air, and also velocity and direction of a wind near the surface are measured on the meteorological ground near AMM-310. The gathering and handling of an information obtained with the aid of the measuring complex AMM-310 is carried out on the base of computer technology. The basic virtue and advantage of AMM-310 in a comparison with the other methods of research of a boundary layer of an atmosphere is the possibility of a synchronous measurement of meteorological and other physical magnitudes in a 300-meter stratum with any time and high-altitude resolution under any weather conditions.
