The analysis of the structure of the global space market has been carried out, the main trends and trends of its development have been identified, and factors affecting the state of the domestic rocket and space industry have been analyzed. Based on the data obtained, scenarios for the development of the industry have been developed and the probability of their implementation has been determined.

Rocket-space activity in Russia is based on the research and production potential of the country's economy. For its further development, it is necessary to industrialize it, organize the introduction of innovative technologies, create a modern ground infrastructure, reorient the provision of services and production to domestic producers.

The structuring of the global and national markets for space services is based on the use of two main approaches, the difference between which consists in using structuring by customer categories and by type of product (service).

The article deals with titles of songs in modern rock discourse. It studies their structure and meaning. The research showed that the authors widely use there allusions towards works in the field of philosophy and literature.

It shows the need for the development of mathematical models to predict the feasibility of indicators and substantiation of optimal combination of technical solutions for the disintegration of rocks in order to minimize the energy consumption for the realization of a given process.

Simulation based on the probabilistic nature of the properties of rocks allows us to describe the crushing and technological system and the interaction of its elements in a wide range of conditions.

It is shown the need to develop an intelligent system for controlling the operation of disintegration facilities by computer analysis of graphical data on the incoming feed stream and the outflow of the result of disintegration.

Offered new and patented intellectual property in the design of jaw crusher to reduce the energy intensity of the disintegration of rocks.

The example jaw crushers, the necessity of finding new technical and technological solutions, the success of which is largely determined by the ability to ignore the typical and traditional solutions.

It shows the need for a particular type of rock to identify characteristics that predict size distribution of the crushed product, depending on its strength characteristics, size and disintegration parameters.

Shows the main directions of improving the efficiency of these processes: the development of the theoretical foundations of disintegration; development of new methods of disintegration, based on the use of different energy effects on the rocks for preliminary softening structural links, and development on their basis of new designs of crushing equipment.

Some results of research of technologies of disintegration of overburden and enclosing rocks of various genetic types for obtaining building crushed stone are given.

A brief analysis of patents on the design of jaw crushers. A new decision on the design of jaw crusher for the disintegration of the solid rock.

A new decision on the design of jaw crusher for the disintegration of the solid rock.

Are some of the areas of work of the Petrozavodsk State University in the study of processes of disintegration of rocks with the development of new intellectual property.

Are some of the findings of Petrozavodsk State University, aimed at improving the efficiency of the disintegration of rocks in the preparation of building rubble.

Are the features of the technical solutions proposed for the disintegration of rock jaw crushers using vibration.

The present work describes the present conditions for high schools training staff for rocket and space complex in the period of its modernization. The article shows peculiarities of graphic training, demonstrates the experience of BSTU "Voenmech".

The article deals withpseudo-occasional numbers generator value impact on result obtaining in the algorithm of random optimization. Much attention is given to insolvency of the standard pseudorandom number generator Microsoft Office in case of the solution of some random optimization task classes; the authors also offer a variant of solution for revealed problem.

It shows that the increase of efficiency of the disintegration of solid rocks can facilitate innovative solutions that are innovative, original and practical value.

A brief analysis of studies of Petrozavodsk State University in the development of scientific bases of perfection of processes of disintegration of rocks and strong development of new technological and technical solutions in this area.

Assesses some of the ways of rock crushing in a jaw crusher. Showing their features and require removal of shortcomings.

It describes a method of crushing rocks in a jaw crusher to produce crushed stone for construction and road building industries.

It shows that the complexity and diversity of the processes occurring in the continuum of rocks and multistage hierarchical structural defects, the existence of tectonic, thermo-elastic and residual stresses, which vary in time and space requires subtle and sophisticated calculations.

Shows that during drilling crushing of boulders or change them to the side at the expense of compression deformation of surrounding rock in the bottom of the well by the proposed method it is advisable to technological, economic and environmental factors.
