This book analyzes various properties and structures of ice from the point of view to solve problems in civil aviation. The Arctic zone of the Russian Federation, together with large territories of Siberia and the Far East, is a zone, that is insufficiently provided with ground navigation facilities, as well as platforms and airfields for landing aircraft, including in the event of unpredictable situations. However, most of this area, especially in winter, is covered with ice, which can be used to solve this problem. The possibility of using ice sheets for the construction of airfields or the location of ground-based flight support facilities requires careful study and analysis. This book is devoted to the study of the properties and structure of ice, with a view for use in civil aviation to construct ice airfields and the placement of ground-based flight support facilities.
This book highlights issues related to the organization and improvement of the efficiency of training system in technical operation of radio-electronic equipment currently used in civil aviation. The increasing intensity of air traffic around the world leads to a quantitative increase in old problems and the emergence of qualitatively new ones that can only be solved by trained people, whose training process should be carried out on a systematic basis. Modern approaches to improving the human resources potential of civil aviation, as a rule, are based only on modernizing the management mechanisms of the training system. One of the main advantages of this book is the unique integrated approach to building a system for training aviation personnel in the field of technical operation of radio-electronic equipment and air traffic control, which consists in taking into account various factors that affect the training of specialists, promising areas of development of civil aviation based on the analysis of various guidance documents and the construction of mathematical models that give a qualitative assessment of existing methods and the proposed new methodology. The book contains a large amount of visual illustrative material showing the existing structure of the system of training in the field of civil aviation.
Mathematical modelling is ubiquitous. Almost every book in exact science touches on mathematical models of a certain class of phenomena, on more or less speci?c approaches to construction and investigation of models, on their applications, etc. As many textbooks with similar titles, Part I of our book is devoted to general qu- tions of modelling. Part II re?ects our professional interests as physicists who spent much time to investigations in the ?eld of non-linear dynamics and mathematical modelling from discrete sequences of experimental measurements (time series). The latter direction of research is known for a long time as “system identi?cation” in the framework of mathematical statistics and automatic control theory. It has its roots in the problem of approximating experimental data points on a plane with a smooth curve. Currently, researchers aim at the description of complex behaviour (irregular, chaotic, non-stationary and noise-corrupted signals which are typical of real-world objects and phenomena) with relatively simple non-linear differential or difference model equations rather than with cumbersome explicit functions of time. In the second half of the twentieth century, it has become clear that such equations of a s- ?ciently low order can exhibit non-trivial solutions that promise suf?ciently simple modelling of complex processes; according to the concepts of non-linear dynamics, chaotic regimes can be demonstrated already by a third-order non-linear ordinary differential equation, while complex behaviour in a linear model can be induced either by random in?uence (noise) or by a very high order of equations.
This book highlights the capabilities and limitations of radar and air navigation. It discusses issues related to the physical principles of an electromagnetic field, the structure of radar information, and ways to transmit it. Attention is paid to the classification of radio waves used for transmitting radar information, as well as to the physical description of their propagation media. The third part of the book addresses issues related to the current state of navigation systems used in civil aviation and the prospects for their development in the future, as well as the history of satellite radio navigation systems. The book may be useful for schoolchildren, interested in the problems of radar and air navigation.
This book presents a technical solution to ensuring the noise immunity of navigation systems in civil aviation aircrafts at the stages of their terminal procedures. It highlights instrumental precision approaches to landing and landing in automatic mode using satellite and inertial radio navigation systems and ground-based augmentation used as the primary means, in accordance with the ICAO requirements. The book is intended for engineering and technical specialists engaged in the development, manufacture and operation of on-board radio electronic systems of aircrafts and ground-based radio engineering support for flights, as well as graduate students and senior students of radio engineering specialties. It is also useful for professionals whose activities are related to air traffic control.
This book describes in detail a method of direct optimization, which makes it possible to choose the best trajectory of an aircraft in conditions of its limited resource. This can happen in the event of an emergency on board, associated with both a possible equipment failure and external influences, for example, when lightning strikes an aircraft or collides with a moving object. The highlight of this book is the fact that the results presented in it can be applied universally to the choice of the flight path of large and small aircraft, as well as helicopter technology. In addition, they take into account various conditions of aircraft flight, including a possible accident. The methods and algorithms presented here can be used as the basis for the creation of automatic collision avoidance systems, as well as the choice of the best aircraft trajectory for flights in different regions and in different conditions.
The characters in Novikov’s work are predominantly people of the Russian North: Pomors, Karelians and Komi. In 2013 Novikov, along with other Karelian writers, proclaimed the Manifesto on a New Northern Prose, the mission of which Novikov described as: “Though these are trying times for Russian literature, there is light, there is hope that it will retain its key underlying principles of honesty, faith, beauty. How great it is that these principles fully fit with and correspond to the old and new, living, and strong direction of Russia’s Northern Prose!” *** The protagonist of A Flame Out at Sea heads to the stores of the northern lakes and the White Sea in search of its present, which unexpectedly proves to be inseparable from its recent past. Against the backdrop of the powerful northern elements, the drama of a single individual in the here and now begins to seem tiny and insignificant but the tragedy of the nation irredeemably large. "The novel is a confession, a travelogue and a doorway into a great historical era.” A Flame Out at Sea is about going beyond the boundaries of the big city, about overcoming the fetters of one’s private and family past, leaving aside one’s resentment, squashing one’s pride, unclenching one’s fists and turning one’s life around. It is about a journey to the origins of speech, personality, courage and love made by a modern man in the harsh, sacred, nourishing and draining circumstances of the Russian North. (Valeria Pustovaya, Literary critic) Translated from the Russian by Christopher Culver Published with support of the Russian Booker Foundation Sponsored by GLOBEXBANK Publishers Maxim Hodak & Max Mendor
This book presents a methodology for assessing environmental safety in civil aviation. The methodology allows the comparison of different technological processes and evaluates their impact on the environment. At the same time, the medical and demographic indicators for ecologically unfavorable territories are compared with similar indicators in the control (background) territories in the same climatic and geographical zones. This book contains methodological recommendations for the creation of the system for ecology safety in the organizational structures of civil aviation. This book is useful to a wide audience—students of aviation, lecturers, as well as specialists in the field of ecology and those involved in ensuring the necessary ecology requirements at aviation enterprises.
The Siege of Leningrad was one of the most brutal battles of the Second World War. The second largest and most populous city in the Soviet Union, Leningrad, now St. Petersburg, was one of the three priority targets of the German invasion, Operation Barbarossa. A total of 333 large military factories were concentrated in Leningrad and, accordingly, 565,000 workers lived there, producing tanks, aircraft, artillery and warships. On 10 July 1941, German tank divisions, having broken through the front south of the city of Pskov, reached the town of Luga. From there, Hitler’s forces had just over 110 miles to go to Leningrad. Meanwhile, the city was feverishly preparing for defense. Stalin’s deputies, Zhdanov and Voroshilov, planned to use the entire combat-ready population of Leningrad for that purpose. Believing that the city would soon be captured by the Germans, Stalin ordered the immediate evacuation of military factories and skilled workers from Leningrad to the East. Before the city was completely blockaded, most of the valuable equipment had been removed. However, the remaining civilian population, including about 400,000 children, were left to their fate. In early September 1941, German divisions supported by the Luftwaffe’s VIII Fliegerkorps, captured the town of Shlisselburg. Leningrad was now cut off from the rest of the Soviet Union. Hitler believed that the city would soon echo to the sound of German jackboots. Leningrad, however, did not give up. In the autumn of 1941, the Wehrmacht did not have enough forces to take the city and for three long years the main means of fighting its defenders were the Luftwaffe and long-range artillery. In September 1941, when the systematic bombing and shelling began, many thousands of families tried to leave Leningrad, but nearly all of the escape routes were cut off. Food supplies in the city sharply decreased. In this book the authors explore the full story of the German and Soviet aerial battles in the Leningrad sector during the siege. There are devastating details of the bombing of the starving population, numerous attempts by the Luftwaffe to destroy the Red Baltic Fleet, and air attacks against the ‘Road of Life’, along which vital food and ammunition were delivered to the city, and combats in the skies over Leningrad and its surroundings. Revealing what was happening in the air and on the ground, as well as in the German and Russian headquarters, the authors explain why, in spite of numerous successes, the Luftwaffe failed to help force the surrender of Leningrad.
This is the first book to view problems of electromechanics through the lens of analytical mechanics. It offers fundamental results in the theory of non-linear electromechanical systems and includes examples of industrial applications.
This is the first book to generalize and analyze the extensive experimental and theoretical results on the phase composition, structure, and properties of aluminum alloys containing scandium. The effects of scandium on these properties are studied from a physico- chemical viewpoint. The authors present binary, ternary, and more complex phase diagrams for these alloys and consider in detail recrystallization, superplastic behavior, and decomposition of supersaturated solid solutions and the effects of solidification conditions on phase equilibria.
