  In this article are viewing the automatic operational regulation by closed gap of forging press with frequency-controlled drive application. Frequency-controlled drive producing by KEB company and consist of frequency converter 18.F5.M1H-3AEA and synchronous motor F2.SM.000-2400. Forging press is equipped with eccentric mechanism regulation of closed gap press, embodied in punch slide. Using the control system by mechanism regulation of closed gap press in automatic mode, will be allow to elevate the accuracy of forged piece high dimension. Regulation is performed on elastic deformation size. Using the automatic control system mechanism regulation and elevate the accuracy of forged piece high dimension will be permit to reduce number of the next mechanical processing of forged piece. The operation by frequency-controlled drive can be produce with computer or PLC application. The accuracy of control by frequency-controlled drive is ±1 degree from destination point of shaft drive. It will allow to realize precision positioning by mechanism regulation of closed gap press and therefore the linear positioning by press slide.

 In production and repair of aircraft gas turbine engines there is currently a great problem related to cleaning of turbine blades' cooling channels from various types of contamination. Nowadays a variety of cleaning methods has been invented which can be used for efficient cleaning of inner cavities. At the same time there is a problem of cleaning quality inspection in serial production. The article reports on the issue of cleaning quality inspection in modern gas turbine engineering.

Term use "the information-educational environment" an essence reflexion of the situation which have developed in a traditional education system when was considered that it is system the organised set of databases of the information networks realising educational activity. Later there was a concept of "the information-pedagogical environment", presence of the databases realising information processes of open formation including besides. The concept "information field" of systems of the open remote formation, designating interrelations of information environments in a uniform information field has been put into circulation.

We discuss the problem of approximate three-dimensional dynamic system attainability domain construction.  We study neuronet-based solving approaches. As an example we discuss application of these methods for approximate construction of aircraft attainability domain distant scope.

  The article is dedicated to development of nonlinear dynamic model of turning process that describes auto-oscillation of cutting tool

 We discuss the problem of approximate two-dimensional dynamic system attainability domain construction. We study neuronet-based solving approaches. As an example we discuss application of these methods for approximate construction of aircraft attainability domain distant scope.

This research in the field of extrapolation has begun in 2008 from developing model for extrapolation day ahead price on Russian energy market. Lately we notice that general idea of method is new so we decided to expand it for other pseudo random sequences. Objective of research is to obtain general algorithm of extrapolation of different pseudo random process (market and physical). We would like to implement comparison to any other models so we are open for any kind of cooperation

  Manner of the fixing of the defensive coating (covering) on blade is presented in publication. The Manner comprises of itself pressing stocking up, which consisting of two heterogeneous metals. The Internal part of composite stocking up is a base, and external part - a defensive covering. As a result got stocking up has a reliable defensive covering, which guarantee protection of the base metal when he working in gas ambience and under high temperature.

  The Publication is dedicated to research of the structure composite material, which is got after pressing in briquette two alloys on base aluminum. The Source material - a briquette with determined by structure - is subjected to pressing under different temperature. Is it Herewith researched nature of the change the structure and deforming a component of composite material.

  On the basis of the offered technique analytical dependences in a general view for definition of the geometrical sizes of preparation under cold rolling of shovels of gas turbine engines are established.

The model of convective and diffusion transfer in rod bundle with mixing grids was developed. Result of calculations were compared with experimental data. Heat transfer in simulation of fuel bundle of WWER-1000 were modeled

In given article the design of the experimental fuel assembly is considered, allowing to conduct tests of fuel elements in the conditions of the reactor core of a nuclear reactor.

  Main factors affecting the formation of business capital structure are examined. The possibility and appropriateness of application of hierarchy analysis method are shown, concerning the choice of efficient capital structure.

The method of synthesis of the quasi-optimal field distribution in the mirror collimator work zone is taken up. The algorithm allowing to calculate the field in the collimator work zone with the help of computer simulation by surface current method is presented. The structure of the field in the work zone corresponding to quasi-optimal current distribution on the offset collimator surface is shown.

At designing  the tool on the basis of a carving-forming mill the basic attention is necessary to give it carving-forming to a part which influences accuracy of a profile of a cut carving.

In clause the comparative analysis of the tools of creation most popular on today and supports of informational resources is resulted. At research the special attention was given questions of the organization of access to informational resources of an electronic collection and methods of adapting of user interfaces to a concrete direction of a data domain of activity

Ways of increase of capacity of nuclear reactor core of a pressurized water reactor are considered. The special attention is given a way of increase of capacity at the expense of leaving from boiling crisis.

This article presents an experience of using magnetic materials in the space branch, which was saved up in Lavochkin Association.

In article working out of full and consistent functional model of a control system by medical diagnostic services is described carried out with use of the structural approach to designing

English language publications covering optimal insulin doses forecasting methods for insulin-dependant diabetes patients are presented in this review. Mathematical models of insulin dynamics in human body, neural network-based and composite algorithms and optimal insulin dose forecasting systems are considered.
