The application of displaced trajectories in tasks of aircraft navigation in time
Authors: Markelov V V 
Published: December 2019

Abstract
Modern requirements in accuracy of aircraft flight trajectory following is done with specifications to the systems of zone navigation in the international air space RNAV (Area Navigation) and RNP (Required Navigation Performance) may apply tight restrictions for the possibilities to correct for the aircraft arrival time to the points of route. Applying the flight speed varying is often insufficient to be on the time chart because of restricted range of available speeds. Application of standard waiting zones in route and in the vicinity of the airport to eliminate the time excess is restricted to the value of minimal flight time which is around 4 minutes or more. As an alternative for arrival time excess elimination to the necessary route point you may use the method of parallel displaced trajectories which is supported functionally with RNP systems. This method is done in the on-board navigation system navigation in time. Depending on the value of the time arrival excess to the necessary route point the navigation coil in time creates the recommendations for the crew how to use displayed trajectories to form the necessary point of exiting to the displaced trajectory to define the side displacement and to evaluate the arrival time correction.
Vibration diagnostics of plates of knife refiners
Authors: Vikharev S N 
Published: December 2019

Abstract
The subject of the research is the diagnosis of the technical condition of the plate of knife refiners. The technical diagnosis of a knife plate consists of determining the stability of the inter-knife gap and the degree of the plate wear. The paper explores the dynamic effects of a plate on a fibrous material. It is shown that the main source of high-frequency vibration of the stator is pressure pulses that occur when the rotor and stator knives cross. The influence of the rotor speed and the number and angle of intersection of the plate knives on the nature of the stator vibration spectrum is studied. It is concluded that the intensity of the effect of the plate on the fibrous material increases from the centre to the periphery. A formula is proposed for determining plate frequencies taking into account the Doppler effect. The vibration diagnostics of the rotor beats is based on the resonance-demodulation method. Estimating the depth of the amplitude modulation of vibrational acceleration of the stator at the maximum plate frequency with harmonics of the working frequency, it is possible to judge the amount of beating of the rotor plate. A device was developed for vibration diagnostics of the beats of a rotor plate of a disk mill. The developed methods and tools can be used in other industries, for example, in mining and metallurgy.

Abstract
Rational nature management, recognized throughout the world as the dominant trend in the development of the economy, involves the most complete use of plant raw materials consumed by humans. For example, in the nutritional structure of people in most countries, plant proteins predominate over animal ones. In Japan, this ratio is 78.3 and 21.7; in Ukraine - 72.3 and 27.7; in the USA - 65.3 and 32.9; in Great Britain – 61 and 32.4; in Germany - 65.3 and 34.7; in France - 60 and 40; in Canada - 68.4 and 31.6; in China –87.3 and 12.7; in Italy - 74.6 and 25.4. A significant contribution to solving this problem is made by the correct storage of the collected agricultural raw materials at the stage of preparing them for processing. Given the significant amount of root crops, grains and seeds in edible plant raw materials, the interest of food producers to the conditions and modes of their storage becomes clear. Modern storages used for these purposes are equipped with various means to provide the necessary heat and humidity conditions; they even can regulate the composition of the environment in the premises of direct placement of stored mounds of root crops, grain and seeds. The paper considers the possibilities of the analytical assessment of the conditions for such storage of these mounds that would ensure their maximum preservation.

Abstract
The structures and model parameters of the hydrotreating reactor of a catalytic reforming unit were identified based on available information of various types. The structural identification of the developed reactor models was carried out on the basis of the ideas of the sequential switching of regressors method, and the parameters were identified using the least squares method modified for working in a fuzzy environment. The developed models have the structure of nonlinear regression models (for output, i.e. hydrogenated) and fuzzy multiple regression equations (for qualitative indicators of hydrogenated). When developing the models with the source information, we used available statistical and experimental data describing the operation of the reactor and fuzzy information representing the knowledge, experience and judgment of experts about the hydrotreatment process. Based on the simulation of the hydrotreatment reactor, a graph of the temperature dependence of the hydrogenate yield of the reactor is constructed. A linguistic model has been constructed that estimates the dependence of the temperature of the hydrotreating process on the quality of the feedstock. This model allows to determine the optimal temperature value in a fuzzy environment depending on the quality of the raw material being cleaned.

Features of heat transfer by radiation in a diesel combustion chamber when operating on gas engine fuel
Authors: Likhanov V A , Rossokhin A V 
Published: December 2019

Abstract
The use of compressed natural gas as automotive fuel in automotive diesel engines allows solving a number of problems that cannot be overcome when working on traditional diesel fuel. First of all, this is a problem of reducing dependence on oil fuel, since the cost of the latter is steadily increasing due to the depletion of oil reserves. Secondly, the use of natural gas can significantly reduce emissions of harmful substances from exhaust gases. First of all, this applies to soot particles. But it is precisely this fact that has a key influence on the fraction of heat transmitted by radiation from the working fluid, since it is the soot particles that affect the radiation characteristics of the flame. The paper discusses exactly how this happens, quantitative indicators of radiation heat transfer are given.

Abstract
The modern automatic warehouse of industrial production is equipped with sensors to determine the type, size, weight, expire date of each SKU. There are also robots for moving SKUs, control algorithms, and an interface for interacting with external services. When developing such a cyber physical system, it is necessary to optimize its main parameters. In engineering, only 2-3% of the whole time is spent on the processing of parts. The substantial time is spent on interoperational storage and transportation. The productivity of the automatic warehouse determines the economic performance of the enterprise as a whole. In addition, the assortment and emergent stock of products stored in the warehouse should ensure stable work under conditions of a change in the production program. This paper is devoted to the algorithm that underlies the digital interaction of an automatic warehouse as a cyber-physical system.

Authors: Afanasyev Alexander S , Terentyeva Valeria A , Tarasov Ivan V 
Published: December 2019

Abstract
The full disclosure of the potential capabilities of buses requires an assessment of the effectiveness of their operation for a number of relevant requirements. The modern regulatory and technical framework for the operation of buses provides high requirements in accordance with environmental and safety standards throughout the life cycle. Therefore, today, the bus fleet structure management system should consider indicators of the quality of their operation, as well as the design stage, in the process of operation and subsequent disposal. Accordingly, the properties of the bus, which are part of the quality, should be practically implemented (correlated) in accordance with the variable parameters of the operating environment over the entire life cycle. At present, taking into account the technical and operational indicators of buses, it is averaged to change the individual groups of indicators of quality, as for an individual object, and for their totality in the structure of the park. The fundamental difference between the developed hierarchy of goals and the subsystems of the control structure system of a bus is to take the level of traditional complex quality criteria into account - to ensure reliability, such as environmental and structural safety and the ability to implement an environmentally sound business environment.

Abstract
This article proposes a method and tool for assessing the quality of assembly and technical condition of the electric drive of the exoskeleton, on the basis of its moment of starting as one of the main indicators of the level of degradation of its components. The existing methods are based on the determination of the moment of starting with the help of additional devices that require the participation of the operator in the measurement process, which increases its time and labor costs and makes it difficult to automate. In contrast to the existing methods and tools, the proposed in this article method and hardware-software complex, allow you to automate the measurement process, do not require expensive equipment and can perform monitoring of the technical condition without dismantling the drive from the exoskeleton. In the experimental part of this article, the proposed method and tool were evaluated on the basis of electric drives with reducers for Electromechanical orthosis of the lower limb exoskeleton. In the course of experimental studies, for the first time, the dependences of the residual life and the efficiency of the electric drive on the moment of moving the input shaft of the gearbox were determined. The results obtained allow us to conditionally determine the level of resource development and the efficiency of the electric drive, based on the measurement of its starting moment, which allows us to carry out maintenance of gearboxes and electric drives according to their actual condition, adjust their maintenance schedule and replacement time, and also increases the reliability of the product in use.

Published: December 2019

Abstract
This paper presents analysis of optical images of films obtained by evaporation (293 K) of a thin layer of low-concentrated (1% wt.) aqueous soot suspensions in a Petri dish. Suspensions of wood, fullerene and diamond-containing (after detonation synthesis) soot were prepared using hydrodynamic dispersion in a cavitation mixer with a wedge-shaped cavitator with the rotor’s angular velocity of rotation being 10000 rpm. The components of the hydrodynamic dispersion process are turbulent micro-mixing and bubble cavitation. As a result of intense turbulence, carbon suspensions assumed properties of non-equilibrium systems. The images of an optical microscope revealed self-organized dissipative micron-sized structures in the dried films being present there in the form of chain, branched and ring-shaped cluster fractals of various dimensions that look very similar to nanotubes. The self-assembling effect was identified for all the types of suspensions under study. The EPR method was used to study the change in the electronic structure of soot resulting from the exposure to high temperatures and pressures that occur when the cavitation bubbles collapse (cavitational activation). The dynamics of changes in dissipative structures in the process of film drying was monitored.

Authors: Dorrer Georgy 
Published: December 2019

Abstract
This paper presents the methods of mathematical modeling and managing on some dangerous dynamic processes on the Earth surface such as floods, wildfires, desertification, oil spills on the water surface and others. We call these processes by a common name - distribution processes. The Hamilton mechanics methods permit to describe uniformly wide class of dynamic processes - both the processes of control determined with the ordinary differential equations and the processes in the continuous beds. The basic model of the distributed processes was presented in form of Hamilton – Jacoby equation. The concept of the normal speed of the process front movement suggested. The indicatrix and figurotrise of spread, which determine the configuration of the distribution process, are introduced. A model of processes with dissipation is proposed. Classification of processes according to the degree of their mobility is given. Using the figurotrises a new approach to numerical modeling of the processes front propagation based on Godunov’s method of the movable grids proposed. Its essence is that the calculated grid is not given a priory, but it is determined by current solution of the problem. It moves and develops with the solution. The movable grid method can serve as a basis for creating agent models of propagation processes. A separate section of the paper is devoted to describing a method for managing the processes. In particular, the fundamentals of the so-called localization control, which consists in building an obstacle insurmountable for the process, are outlined. The proposed methods and algorithms are illustrated by numerical examples. The models presented in this paper was a theoretical basis for designing and developing some management systems of the distribution processes control.
