Dependence of the extent to which the space vehicle’s own atmosphere and plasma generated by stationary plasma engines affect the space vehicle on its structural lay-out
Testoyedov N.A., Smirnov V.A.
Abstract

The paper describes the mechanisms of influence of the space vehicle’s own atmosphere (OA) and plasma generated by stationary plasma engines (SPE) on the space vehicle. The results of investigating the extent to which these factors depend on the structural layout (SLO) of the space vehicle are given. Ways of minimizing the negative effect of OA and plasma generated by SPE at the stage of choosing the space vehicle’s SLO are planned.

Development and analysis of compressed bending process in a die with an elastic punch
Komarov A.D., Yeskina Y.V., Ponikarova N.Y.
Abstract

A die design has been developed for compressed bending of sheet articles and cutting blanks off a strip in one stroke of the press. The die provides increased thickness of material in the bending area, reduction of the radius of bending and spring back, which improves the strength, rigidity, quality and life of the articles as well as labour productivity. The procedure for calculating the basic parameters of article production process is given. The die design has been patented.

Friction control on changing parameters of friction pairs using sequential feeders
Rybaltchenko D.Y., Bystrov N.D.
Abstract

Comparative analysis of functional possibilities of sequential lubrication systems with the control of a given period of lubrication material renewal and changing parameters of the lubricated friction pairs is carried out. Calculation tables are given that are used when designing a sequential lubrication system with a liquid lubricant, a SEHY-P 400/400 hard table taken as an example. The main conditions of the operation of a lubrication system with lubrication control on changing parameters of friction pairs on the basis of a pumping device with programmable lubricant feeding is considered.

Algorithms and devices for input signal identification in problems of dynamic object control and diagnostics
Zasov V.A., Tarabardin M.A., Nikonorov Y.N.
Abstract

The paper deals with the problem of separation of individual signals from the additive mixture of several signals, i. e. the problem of signal identification.

Romanenko V.A.
Abstract

The task of optimizing the parameters of the system of serving leaving passengers at the check-in stage in the airport building has been solved by using the method of statistical modeling. Time characteristics of the check-in stage and the capacity of the check-in system which minimize time losses and provide the proper level of comfort for passengers have been determined. Detailed stochastic portraits of passenger service system functioning for the actual conditions of operation of the International Kurumotch airport (Samara) have been obtained.

Method of fault detection and diagnosis in linear stochastic systems in the process of filtration
Tsyganova Y.V.
Abstract

A computationally efficient method of fault detection and its identification in the class of linear stochastic control systems in the process of filtration has been obtained. The efficiency of the method lies in the fact that a decision is taken on a limited set of likelihood function values, the values being computed directly in terms of values generated by the filter.
