ROCKETS AND ARTIFICIAL EARTH SATELLITES Pokrovskiy on Engines for Space Craft An article by Prof G. Pokrovskiy, Doctor of Technical Sciences, which appeared in Sovetskaya Aviatsiya and deals with engines for cosmic rockets, in based on materials in the foreign press. Discussing the possibilities of building thermal rocket engines, Prof Pokrovskiy states that one of the most important theoretical problems is finding the moans for speeding up the velocity of the jet gases. He rejects some of the suggestions for achieving this, as for example, that of using unstable-type molecules, the so-called free radicals, as being inefficient and yielding too low an ac- celeration. As for the use of nuclear energy for additional heating of the jet gases, Pokrovskiy explains that the heated gas molecules move chaotically in all directions, not only forming a jet, but also striking the walls of the combustion chamber and heating them to such high tempera- tures that they melt and are destroyed. Pokrovskiy suggests a method of controlling the movement of the mole- cules involving the producing of ions through preliminary heating of the molecules. This means that the thermal jet engine would need to be replaced by an electric accelerator o1` elementary particles. The ions can be made to move in strong electrical fields. This is the ion rocket. It consists of an ion accelerator, the electric power for which would be produced from a compact atomic power plant in the body of the rocket. A possible obstacle to such a rocket is that the rocket and the ion stream will have opposite electrical charges which will cancel one another. This can be avoided by simply using two accelerators in the rocket, one emitting positive and the other negative ions. It should be remembered tbaty in.certain cases, the presence of a con- ;i.dcrablo electrical charge on a space craft can be "t significant factor ..n apace navigation, says Pokrovskiy. As is known, there are magnetic and electrical fields of force in the Universe which can be used for moving a space ship if a sufficiently large electrical charge (positive or negative) is imparted to it. Pokrovskiy then discusses the photon rocket, saying that all present designs for such rockets are infeasible in that the photons cannot be con- trolled and given direction. They move chaotically, as do the heated mole- cules. Therefore, all plans of making a photon rocket are useless until this problem is solved. The most promising form of rocket power, in view of present technical conditions, is the prospect of using the ion motor. This does not mean, says Professor Pokrovskiy, that the ion motor will completely supplant the thermal rocket motor. The latter will, no doubt, fully retain its value for slowly moving rockets and for the first stages of cosmic rockets. The ion rockets themselves will be used as the last staga of rockets intended for flights beyond the limits of the solar system. ("Cosmic ocket Motors," by G.

UPPER ATMOSPHERE Measurement of the Polarization of Skylight The measurement principle, design, and operation of a new photoelectric poLarimeter is described. The instrument operates together with a secondary electron multiplier and gives the degree of polarization immediately and directly. The special measuring procedure eliminates the influence of the sensitivity fluctuations of the multiplier on the measurement results. The general design and the mechanical and electrical assembly of the measuring device were done by H. Krecker, special mechanic at the Gotha Research Station. His predecessor, K. Eichler, built the amplifier. Sekera and his associates (Investigation of Polarization of Skylight, Final Report (1955), Contract No 19 122 -239 developed independently, at about the same time, a recording polarimeter which operates on a very similar principle.

METEOROLOGY Soviet Book on Aperiodicity of Cynoptic Processes The 196-page book Pre emctvennost' Nekotorykh Tipov Sin ticheskikh Protsessov (The Aperiodicity of Certain Types of Synoptic Processes)), by E. A. Isayev, published in 1958 by Gidrometeoizdat, Leningrad, presents an exhaustive treatment of the data and evidence to support the theory of the eperiodicity of synoptic processes. Chapter 1, which presents a general survey of the literature, dis- cusses the Shuleykin theory of thermobaric waves, the dynamic peculiarities of waves and of synoptic processes, the application of peridogrammic ana- lysis in meteorology, and a study of the rhythmic, as well as the aperiodic, properties of synoptic processes, including the rhythmic properties of sy- noptic processes according to B. P. Mul'tanovskiy. Chapter 2 gives a brief account of the mechanisms of atmospheric cir- culation and discusses the interrelationship of activity centers and the mechanism of cold and heat waves from the viewpoint of rhythm (periodicity) or aperiodicity.

Chapter 4 and Chapter 5 discuss the aperiodicity of the microsynopt- ical processes, which lead, in both spring and fall, to steady changes of temperature through 0 degrees, and divide these processes into four classes: early-accelerated, early-retarded, late-accelerated, and late-retarded. Chapter 6 points out the aperiodicity of certain types of seasonal circulation leading to a drop of temperature over the European territory of the USSR and in Western Siberia. The discussion includes the aperiod- icity of ultrapolar synoptical processes. Chapter 7 gives synoptical data, including charts of the recurrence of cyclones and anticyclones. The probability of aperiodicity of synopt- ical processes and the probability of the recurrence of temperature within certain limits in the case of different types of processes are discussed. Chapter 8 discusses the aperiodicity of synoptical processes which lead to a rise in temperature over the European territory of the USSR and Western Siberia. The aperiodicity of heat waves caused by southern pro- cesses and by western processes are emphasized. An appendix gives 14 pages of data on which the probability of aperi- odicity was established. Machine Weather Forecasts Being Developed The day is not far off when weather forecasts will be made entirely with the aid of machines, says L. Pubanova, in Sovetskaya Aviateiya, in reporting on a trip to the Central Institute of Forecasts, where new, more accurate methods of weather prediction are being developed. The idea of making meteorology a precise science was advanced 40 years .Co. Standing before scientists was the problem of giving weather forecasts by a quantitive method. This was accomplished by the use of mathematical equations describing the physical processes. Involved. Solving these equa- tions makes it possible to obtain a representation of how these processes take place. The first attempt to work out equations was attempted in the 1920s but was not successful. A number of difficulties confronted researcher, one of which was that science lacked sufficient data on the different states of the atmosphere. In addition, technology was not sufficiently advanced to be able to quickly solve the complex equations.

A. Kibel'. He succeeded in defining the most essential of the factors which form weather and, for the first times, pointed out a practically admissible method of solving equations for a short-range forecast. The use of high speed computers made the rapid solution of difficult equations possible. Specialized computers, designed for the solution of a specific class of problems, are now gaining wide circulation, along with universal com- puters. One such machine is the "Pogoda," which is being operated by the Central Institute of Forecasts. The Pogoda contains about 400 tubes, several thousand semiconductor diodes, etc. The machine automatically carries out operations of addition, subtraction, derivation of square roots, etc. It produces calculations of certain elements of the weather necessary for the compilation of forecasts for different periods of time. A system of command is employed by the 'machine, consisting of 14 in- structions. Mathematical operations with five-digit numbers are carried out at a speed of 200 operations per second. Engr P. Potievskiy described the machine's operation in calculating weather forecasts. Initial numerical material is placed on tape with the aid of a special code and is transferred by means of a keying device into a perforator by the operator. Here, the material is automatically placed on another tape. Two identical perforated tapes are prepared independently of each other in order to avoid errors in plotting. A control-reading de- vice automatically checks them; the tapes pass under photodiodes and, in the case of an error, are stopped. The errors are corrected. Instructions to the machine, that is, the program of its operation, are plotted on these same perforated tapes. Then, the prepared tapes are introduced into the input device of the machine. If the results are the final aim of the so- lution of the problem, then they are given out by a printing apparatus. If these same results are only initial data for another problem (intermed- iate results), then they are placed in the machine for further calculations. An enormous quantity of operations (over a million) are necessary for the solution of one of the problems of forecasting and require about 2 hours. However, the mathematical possibilities of the machine are still not exhausted. ("A Machine Will co pute Weather Forecasts," by L. Rubanova; Moscow, Sovet- .skaya Aviatsiya, 5 Aug 59, p 4). -4- Sanitized - Approved For Release : CIA-RDP82-00141 R000200830001-1 Sanitized - Approved For Release : CIA-RDP82-00141 R000200830001-1 Now Soviet Instrument for Determining the Turbulent Flow of Heat A new apparatus for direct measurement of the turbulent flow of heat by the pulse method was developed in the Institute of the Physics of the Atmosphere. The results of testing the instrument are given. The apparatus makes it possible to obtain directly the value of the turbulent flow of heat owing to the linearity of the transducers (acoustical microanemometer and a pulse resistance thermometer) being used and with the use of a corre- lometer. Pulse measurements are accompanied by gradient; measurements. Dimensionless empirical functions, entering in the formula for deter- mining the turbulent flow of heat according to the data of gradient observa- tions, are constructed. The case of unstable stratification is studied, and the value of a universal constant characterizing the regimen of free convection close to the value found by Priestley ("Free and Forced Convec- tion in the Ground," Quart. Jour. Roy. Meteorol Soc., No 348, 1955, p 81), is obtained. ("Determination of the Turbulent Flow of Heat," by A. V. Perepelkina, Institute of the Physics of the Atmosphere, Academy of Sciences USSR; Moscow, Izvestiya Akademii Nauk SSSR, Seriya Geofi'zichesk4Ya,, No 7, Jul 59, pp 1026-1035) Electrical Charges of Cloud Droplets The results of the investigation of the distribution of electrical charges in natural clouds in relation to the time of their existence are presented by A. P, Sergieva, Institute of Applied Geophysics, Academy of Sciences JSSR.. It is shown that the charges of the droplets affect their coagulation. The preferential charging of the cloud droplets is related to the ratio of the concentration of ions in the air during the period preceed- ing the formation of the cloud.

Sergieva; Moscow, Izvestiya Akademii Nauk SSSR, Seriya Geofiziche- skaya) No 7, Jul 59, pp 1018-1025) i3 ider Device Webs No Longer Ma eration of Potsdam Vertical-Current Measur The vertical-current meter described by the author in 1952 (Zeitschrift fuer Meteorologie, Vol 6, 1952, p 271) operated incorrectly during the sum- mer months as a result of spider webs in the pick-up mechanism. Ordinary measures to keep the device free of spider webs met with only limited success. In a new pick-up device, those portions of the instrument which are vulner- able to spider webs now rotate, tearing apart the webs as they are formed. The time constant of the pick-up device vas also calibrated for the mean atmospheric cgnductivityy value at the ground in Potsdam. This latter value is 1.1 . 10-16 Ohm-lcm-l; the time constant for the air at the ground in Pots- dam is, therefore, 805 seconds.

These variables are: divergence and its vertical distribution, the vertical change of the horizontal wind, the ageostrophic portion of the north-south component of the wind, and the heat sources.

Kohlache, Institute for Large-Scale Weather Research, Potsdam; Berlin, Zei- tschrift fuer Meteorologie, No 11/12, Nov/Dec 58, pp 339-344) Observation of a Luminous Column in the Atmosphere in Wittenberg in December 1956 Following is the text of a report on the observation of a luminous column at Wittenberg, East Germany, on 22 December 1958.

SEISMOLOGY Study on Diffraction of P-Waves in Earth's Core The possibility of estimating the shear modulus of the Earth's core on the basis of studying the character of the decrease in the amplitudes of P-waves in the shadow zone is considered. The investi- gations were conducted by a method of modeling because of the consider- able difficulties arising in theoretical considerations of the diffrac- tion of seismic waves in the Earth's core. The studies revealed the possibility of estimatin the shear modulus of the Earth's core (near its boundary with the mantle) according to the character of the P-waves diffracted in the core. It w shown that this value is close to zero or, in any case, less than 107 dynes per square centimeter. ("P-Waves Diffracted in the Earth's Core and Hard- ness of the Earth's Core," by L. N.

OCEANOGRAPHY Chinese Studies on Tidal Currents An article, designated as "Research Report go 81 of the Institute of Oceanography, Academia Sinica," states that the institute, in June 1958, launched the third and fourth series of synchronized, continuous 24-hour' observations from 48 observation points established in the Gulf of Chihli and the western part of the Northern Yellow Sea. Two research vessels of the institute, the Chin-hsing (i . - ) and the Shui- being (7~_ ), were used. The sea current at the surface and at depths of 5, 10, 15, 20, 30, 40, and 50 meters, as well as close to the sea bottom, were measured with different types of current meters. The data thus obtained were used to determine the characteristics and the distribution systems of the tidal currents in the area under study. A method for compiling a perpetual tide table is discussed. The authors mention two previous series of continuous 24-hour ob- servations which were made from these ;stations in March and June 1958, respectively.

ARCTIC AND ANTARCTIC Soviet Scientist Reports Warming of Arctic Weather L. S. Petrov, scientific associate of the Hydrometeorological In- stitute, recently wrote his dissertation for the academic degree of Candidate of Geographical Sciences. In this dissertation, he makes the following statements: "...During a past 50 years, ere have been our p e r i o d s waves o warmer weather, of about equal duration, in the uropean-Asian sector f the Arctic. The first and most pronounced of C PYRG HT hose warmer periods b gan in 1915-1916 and reached its highest point CPYRGHT CPYRGHT 16 At present, the average annual temperature at all polar stations is higher than before the beginning of the last "warmer period." For example, in Barentsburg, the average temperature of the 6-month winter season during the past 5 years was 7-8 degrees higher than about 50 years ago. On Spitsbergen, on Zemlya Frantea Iosifa, and in the northern part of Novaya Zemlya, the maximur average annual temperatures for the 20th Century were recorded during 1952-1956." Petrov notes that the rise in temperature In the high latitudes of the Northern Hemisphere has been exceptional in the last 200-300 years, both as to its extent and consequences. As a result, the glaciers have rapidly retreated to the north, there have been changes in the flora and fauna of the Arctic, the ice regime of the seas has changed, and con- ditions of navigation have improved. L. S. Petrov is of the opinion that the period of warmer weather has now reached its highest point; in a number of regions, temperatures have dropped. In the next few decades, cold and warm periods will probably alternate. ("The Arctic Is Getting Warmer," Leningradskaya Pravda, 26 Jul 59) Activities in Antarctic On 26 July, the present staff at Mirnyy completes 6 months of work in Antarctica. The present antarctic winter is more severe than it was last year. The average temperature at Vostok Is minus 70 degrees cen- tigrade. At the newly built station Lazarev, heavy snowstorms and hurricane winds have covered the buildings with snow. However, work at all stations is proceeding successfully. The scientific groups and teams of the expedition have obtained much valuable information on the nature of Antarctica.

Weather reports are ex- changed daily. Early in May, Soviet pilots flew to the Australian station Wilkes, about 800 kilometers east of Mirnyy, on Knox Land, to bring medical aid to one of the Australian scientists. The flight was made under extremely difficult conditions. The plane had to fly over mountains which were considerably higher than indicated on existing maps. (Such instances happen frequently in Antarctica. Even now, after 3 years of persistent explorations by many expeditions, the relief of the continent is still less known than that of the moon.) ("Antarctic Winter," Moscow, Vechernyaya Moskva, 25 Jul 59) Winter Operations at Soviet Stations During the first half of the antarctic winter, the weather at Mirnyy and at the new station Lazarev, 3,500 kilometers west of Mirnyy, was extremely windy. There were continuous snowstorms. All of the buildings at Mirnyy, except a few situated on elevated spots, and at Iazarev, were covered by snowdrifts. The staff members at Mirnyy now consider that the weather tb calm if the wind velocity is 15 meters per second. Frequently, the winds reach hurricane force. At such times, it io impossible to walk from one building to the next without holding on to the cables strung between them. At the interior station Vostok, the air temperature recently dropped to minus 79.5 degrees centigrade. In such weather, it is hard to re- main outdoors for more than 15-20 minutes. Breathing is possible only with special masks. Kerosene freezes, and diesel fuel becomes so thick that it cannot be pumped. The rubber casings of radiosondes crumble like glass at the slightest vibration. Despite these difficult conditions, the ten Soviet polar scientists headed by V. S. Ignatov, Candidate of Technical Sciences, are conducting regular complex sci- entific observations. Most of the scientific instruments at Vostok have beeci converted to remote-control operation. In addition to planned research activities, a large number of observations are being conducted in Mirnyy, with the joint efforts of several teams.

Shlyakhov, Candidate of Sciences, has been studying the velocity of winds blowing oft the interior (stochnyye vetry) at several remote points and at different altitudes. For this purpose, radar was used, in addition to anemometers. Observations of ice temperature at various depths were conducted, to- gether with the glaciological team. The aerometeorologisas and machine shop workers constructed and set up an original "over-all" (summarnyy) snowstorm meter (metelemer). This instrument enables one to study the movement of snow during snow- storms, with different wind velocities and at different altitudes. During a 2-month period, expedition members worked on Drygelski Island, 90 kilometers from Mirnyy. The climate and weather conditions on this island are very different from Mirnyy and even more different from the interior regions. The studies made on the island are of great interest. In the center of the island, a 43-meter hole was drilled for recording the temperature in various layers of the glacier. These ob- servations, conducted parallel to those at Mirnyy, will provide new ma- terial for comparisons of weather in regions "at sea" (moristyye) and coastal regions. For the first time, observations of auroras with the help of radar were organized at Mirnyy? Reflections of auroras can be observed in Mirnyy mainly from the region where the Australian station Wilkes is located (about 800 kilometers east of Mirnyy). Contact was established with this sty;tion, and it was decided -to conduct joint-studies of auroras. The fall-and-winter interior expedition with "Pingvin" snow vehicles and trailers was completed successfully? A group of geophysicists, headed by S. -N. Shcheglov, had to overcome great difficulties during this trip. Continuous snowstorms, strong winds, and temperatures of minus 40 degrees centigrade or even lower presented almost insurmount- able obstacles. The members of the traverse party conducted a large r.,mber of meteorological, glaciological, and general geographical ob- servations. They traveled 150 kilometers from Mirnyy and reached an altitude of over 1,500 meters above sea level. The whole trip lasted 78 days. The transantarctic expedition to the three poles, i.e., the south geographic, south geomagnetic, and pole of relative inaccessibility, will take place during the spring and summer ,eason of 1959-1960 and will complete the work of the present staff' of the Antarctic Expedition. The traverse will be carried out with three "Khar'kovchanka" snow vehicles and one heavy tractor from the station Komsorol'skaya, where the snow vehicles are now located.

Osipov has given strong support to the scientists during the first half of the winter. The planes are now being prepared for spring and summer flights. In the near future, as soon as calm weather sets in, some of the planes will be transferred to the shore ice. The Fourth Antarctic Expedition is considerably exceeding its work plan under the program of the IGC-1959. An extensive exchange of in- formation with foreign antarctic stations is continuing. -- A. Dralkin, Chief of the Expedition ("On the Sixth Continent," Moscow, Pravda, 16 Aug 59) The Work of the Czechoslovak, Antonin Mrkos, in the Antarctic The large-scale action of the International Geophysical Year has given rise ti lively interest in research work in the Antarctic. A whole series of scientific expeditions have been sent there. by various countries, that of the Soviet Union occupying a foremost place with regard to its equipment and the extent of scientific work carried out. Owing to extensive support and understanding by the Soviet Union, Czechoslovakia was enabled to partlcipate?'in'this great work by sending scientific worker Antonin Mrkos in the Third Soviet Antarctic Expedition, at the suggestion of the Czechoslovak Committee for the 1GY. His task was to carry out the Izechoslovak program of observing airglow and twilight phenomena under the difficult Antarctic conditions. A. Mrkos left Czechoslovakia on 5 October 1957 and returned home, after 19 months, on 5 May 1959. Observation of airglow and twilight phenomena, as well as aurora, was carried out by A. Mrkoi at the Soviet' Antarctic Station, Mirnyy, with an adapted photo-eleceric photometer of the sale type that is used in Czechoslovakia at the Lomnicky Stit and Ondrejov stations. Before his departure, the necessary tests were carried out with his instrument and a comparison made with the photometer at Lomnicky Stit. The actual measurements in the Antarctic were carried out from September 1957 to mid-October 1958, when the Pblar night ended. The results of the ob- servations include measurements from 94 nights and 67 twilights and are now being processed and prepared for publication. Apart from the above-mentioned work, A. Mrkos accompanied Soviet scientists on a march of 2100 kilometers into the interior of Antarctica, from mid-October to the end of December 1958. -During this journey, thayr made, primarily, meteorological observations and ensured astronomical navigation. r Sanitized - Approved For Release : CIA-RDP82-00141 R000200830001-1 Sanitized - Approved For Release : CIA-RDP82-00141 R000200830001-1 On 30 January 1959, A. Mrkos sailed on the ship "Ob" to the coast of Queen Maud tend, where he took part in building the now Soviet Antarctic station "Iwzarev." Ile left the Antarctic for home on 10 March 1959, continuing his observations of airglow and twilight phenomena right up to the coast of Great Britain, where fogs then made this impossible.
