Annotation: Steel hardening technology is considered, which implies modification of the steel surface with the method of ion-plasma nitriding in glow discharge. Ion-plasma nitriding is a multi-factor process, which requires the study of the influence of nitriding process conditions on the structure of modified layers, which, in its turn, determines their mechanical properties. The subjects of research included: austenitic steel 12X18Н10T, carbon steel Ст3 and structural steel 45. There were two conditions of plasma creation during the research: free location of samples on the surface of the cathode (configuration I) and inside the hollow cathode (configuration II). Optimal parameters of the ion-plasma nitriding process have been determined, which provide stability of the process and create conditions for intensive diffusion of nitrogen into the steel surface. Hydrogen was added to the argon-nitrogen gaseous medium to intensify the nitriding process. Working pressure in the chamber was maintained within the range of 250-300 Pa, the duration of the process was 120 minutes. Comparative characteristics of the structure and microhardness of the modified surfaces of the steels under study for two ion-plasma nitriding technologies are presented. Metallographic examination of the structure of the surface modified layers in the cross section showed the presence of the laminated nitrided layer, which consists of different phases and has different depths, depending on the material of the sample and treatment mode. Nitrided layer of 12Х18Н10Т steel consisted of four sublayers: upper “white” nitride layer, double diffuse layer and lower transition layer. The total depth of the nitrided layer after the specified treatment time reached 23 μm, use of hollow cathode increased it by 26% to 29 μm. The nitrided layers of steel Ст3 and steel 45 consisted of two sublayers – thick “white” nitride layer and general diffuse layer with a thickness of about 18 μm. The microhardness of the nitrided layer of steel Ст3 was 480 HV, increasing by 2,5 times, and for steel 45 was 440 HV, increasing by 1,7 times. The use of hollow cathode for these steels reduces the depth of the nitrided layer, but at the same time the microhardness increases due to the formation of a thicker and denser nitride layer on the surface. The results of the conducted research can be used to strengthen the surfaces of the steel parts in rocket and space technology, applying high-strength coatings.
Key words: ion nitriding, glow discharge, cross-sectional layer structure, hardening, microhardness

The goal-oriented educational areas, realized at the enterprise, occupy the special role in these activities. The goal-oriented educational areas represent a complex of actions of several divisions at the enterprise, supervised by the scientific-educational center, which aim to provide the corresponding professional level of the employees busy with fulfilment of current job assignments. Among the most significant are the following areas: training of the executive personnel and its reserve; training in the postgraduate courses of the enterprise; learning computer technologies; preparation of the pre-launch processing personnel and its reserve; activities with intellectual property; involvement of the leading institutes of higher education both for training of young specialists and to obtain particular scientific results etc. All these areas have already been proven and some of them run on continuing basis. Thus it can be concluded that the personnel training system is effective. It proves itself and can serve as an example of introduction at any manufacturing enterprise. Besides, orientation of training process at the individual goal-oriented educational areas involves and unites efforts of several interested enterprise divisions to reach particular and necessary results within certain timetable.
Key words: system of specialist training, goal-oriented educational area, training at the enterprise, professional training.

Annotation: The problem is defined of designing the space rocket low-pressure air thermostating systems joints. The basic requirements imposed to the joints from the side of space rocket and ground complex are determined and stated. For this purpose, the analysis of operating conditions and possible situations during rocket launches is made. Besides, the methodological principles based on problematic, systematic, and structuralfunctional approach were applied using the theoretical and empirical capabilities, attraction of general scientific and special investigation methods, as well as historical and logical methods. The list of topical issues is reflected for implementation in joint’s design. The ways are proposed to create the joints meeting the requirements imposed. As a result, it was ascertained that the joints can be made of simpler and at the same time failure-free design in the form of combined triune rubber hose fitted with a metal fixation/release unit installed on a sealing flange in a special groove. Of special note is the versatility of the proposed technical solution for use in any of the space launch systems known in the world’s practice. The article is concluded with following: the basic requirements have been formulated for ground complexes thermostating systems joints to ensure space rockets prelaunch processing and launch, in doing so, the topical problems were defined; the scientific principles were proposed to design the thermostating systems joints for comprehensive solution of the topical problems , including potential critical situations; the thermostating systems joints have been developed, manufactured and have successfully passed the ground development tests with simulation of the conditions maximally close to operating ones at static operating air pressures and in off-nominal situations.

Annotation: This paper in brief presents the history of cooperation between the Yuzhnoye State Design Office (YSDO) and University’s applied-physics faculty focused on drawing the enterprise specialists to teaching activity at the faculty, and University graduates – to work at the enterprise. Interchange of personnel throughout three periods is analyzed: a) in the remote past (early 1950s – late 1980s); b) watershed years at the turn of millennia (early 1990s – mid 2010s) and c) nowadays (from mid 2010s). Forecast attempt for the near future is also made. Active participation of the outstanding YSDO specialists in the organization and education at the faculty, especially at the first stage of cooperation, is shown. In particular, Y. A. Smetanin, YSDO Deputy General Designer, was the head of department №1, N. S. Shnyakin was the head of department №2, department №3 was chaired by N. F. Gerasyuta – Head of Dynamics, Ballistics and Control Department in YSDO. At that period faculty trained annually all in all ~300 young specialists for Yuzhnoye State Design Office. Great deal of problems and new challenges, which emerged in watershed 1990s, are described. Despite this, close cooperation between the YSDO and faculty was basically maintained. Thus, for example, for several years S. N. Konyukhov, YSDO General Designer, chaired the state examination board on defence of graduation works of the department №1 students. At the same time, number of aerospace specialties graduates this period has sharply decreased to 35 graduates. The present state of affairs, causing concern, is shown. Actual admission rate for the aerospace specialties for the past years suggests that starting with 2022, number of graduates for Yuzhnoye State Design Office can practically reduce to nothing.

Annotation: The range of problems of development testing of thermostating systems mating hoses for the needs of space rocketry building is most topical. In publications, insufficient attention is given to the presented range of problems. The purpose of this article is to fill in this gap. Testing of the hoses performed in accordance with comprehensive program implies a number of sequential tests and has its peculiarities. Generally, these are factory tests, participation in system and integrated tests and participation in flight tests of a space rocket. Special reference was made to the role of accelerated climatic tests, as a part of factory tests, to confirm warranty obligations for the hoses. In conclusion of the article, the concept was formulated on organization of development testing of space rockets thermostating systems hoses that reflects test peculiarities and the conclusion was made that conducting the testing of hoses according to the presented sequence ensures creation of articles that meet the requirements imposed.
