Air and space vehicle production: indicators of innovative activity

Abstract

We analyze the problems of increasing the innovative activity of air and space vehicle manufacturing enterprises in Russia by the year 2021 and consider indicators reflecting the innovative activity of organizations, such as the implementation of innovations, the proportion of organizations engaged in technological innovation, cost of technological innovation by the source of funds, the dynamics of the innovative production output. Besides, correlation analysis of the relationship between the main indicators of innovation activity and the intensity of expenditures on technological innovations has been performed to identify dependencies describing air and space vehicle production’s distinctive features.

Systematic Investigation of two-Phase Flow in Special Channels

“…One of the most important natural and unintended phenomena of this interaction is the mixing of water passing through the structures and the surrounding airflow, which in some cases causes severe reactions between the existing climate and causes considerable damage. This type of current is called "two-phase current" [1][2][3][4]. One of the most important problems in the analysis of two-phase current in pipes is to determine the exact pattern of flow or distribution of liquid and gas phase inside the pipe [5].…”
