The article analyzes the organization of works on standardization of air transport of the Russian Federation in the framework of the activities of the Technical Committee on standardization "Air transport", according to national priorities.
By results of the review, the analysis and use of data of activities [1-8] substantive provisions of a method for fatigue life analysis of shear joint fasteners in metal-composit joints of aircraft structural elements are formulated and presented. It is noticed, that a main objective of working out and application of the presented method – search of the erroneous is constructive-technological decisions yielding unsatisfactory settlement and experimental results on fatigue durability of shear joints in mixed packages.
It considers the task of determination of parasite drag for subsonic commercial airplane on the base of theoretical calculation procedures. It contains the procedure for clarification of empirical approach to calculation of parasite drag at high speeds. It provides examples of calculation of parasite drag at transonic speeds as a result of step behind the slat on the wing of commercial airplane.
There are considered new tasks in aerodynamics in the process of certification of airplanes of transport category. The procedure for optimal location of ice detector at the transonic airplane and means of compliance with certification requirements for automatic engagement of anti-ice protection.
This article describes the results obtained from continuous monitoring of fuel flow on the airplanes Tu-204-300, operated by the aircompany "Vladivostok Avia". The reasons for the change in the cost of each copy of airplane and changes in fuel characteristics due to pilots manner of flying.
The paper presents a web application that facilitates accounting of life cycle of aircraft components and enables aircraft operators to transparently send data to information systems of civil aviation organizations.
The concepts of electronic training sold in a context of specificity of preparation of the air personnel are considered. Is shown, that the introduction of technologies of electronic training is capable to introduce innovations, not used earlier approaches to training the air personnel.
The functional relationship between cumulative probability of maximum load factors and cumulative probability of equivalent load factor amplitudes was determined. This relationship was derived from statistical correlation between cycle ratio and amplitude of load factor suggested on the basis of processing of firefighting flight records of load factor. The cumulative probability of maximum load factors and ground-air-ground cycle maximum load factor calculated through the cumulative probability of equivalent load factor amplitudes obtained using the range-pair cycle counting method have good agreement with the results calculated using the peak counting method.
In this article, we studied results of an estimation of efficiency of interaction in pairs of pilots with use V.V. Gulenko's intertypes relations. It is analysis of results of series of experiments, which have been during 2003–12. In this article, we give the correlations of the received socionic parameters with results of color's sociometry by Etkind A. M., and results of the special computer tests.
This article is devoted to a question of the perfection of psychodiagnostic techniques, as tool of aircraft crew resource management. First of all, article is devoted to increase of the validity of the socionic tests.
The article sets analysis of the state organization and carrying out works on certification of testing equipment and software at tests of the components and units of aviation equipment in the organizations on repair of air transport performed by the Parent organization of the metrological service civil aviation – FSUE State scientific and research institute of civil aviation.
Summary of the research results obtained during the development of the technology of metrological certification and production of standard samples necessary for calibration of the means of diagnostics of aircraft GTE products of wear oils.
An approach allowing one to predict the development of air-route network is proposed. It proceeds from the principle of increasing the accessibility of points of destination, that is to make available for passengers non-stop flights or flights with one transit landing in case of the largest number of routes. With comparative analysis of possible variants of extending the structure of air-route network, it is reasonable to take into account a generalized time parameter and a number of alternative routes for passenger delivery from departure point to point of destination.
The Offered model of the behaviour reologicheskogo bodies (the viscous-elasticity of the materia), designs or systems) under controlling influence of the load, acting on given law for some time.
The necessity of using of heuristic methods take account of uncertainties in each of the transport company activities when choosing a rational variant of the vector control of dynamic processes related to performance indicators, built on the basis of poly-criteria evaluation.
Сonsidered question of reducing oscillations of cargo on helicopter external sling to improve the safety and efficiency of flight operations during the conduct of urgent aerial works. Offered practical recommendations of piloting a helicopter and effective maneuvers to eliminate oscillations of cargo on external sling.
