Published: December 2020

Abstract
Currently, the pandemic has had an extremely negative impact on the economy, especially in the aviation industry. The airfreight’s frequency has not fully recovered. The situation requires appropriate systemic measures to address it. The article describes the organizational and economic mechanisms to improve the Russian aviation’s productivity and identifies the need to review approaches to assess the Russian aviation industry, considering that it has not achieved the target indicators set by the state program. There are two main directions: inclusion of the section “Evaluation of Integrated Aircraft Industry Structures (IS) Efficiency” into the state program, as well as a detailed evaluation of competitiveness and product portfolio of the aircraft industry’s IS, development of IS competitiveness strategy both in the domestic and foreign markets. There have also been considered the prospects of using crowdlending platforms in Russia as an alternative financial instrument to banks in the helicopter technology’s P2B and B2B segments. There several factors facilitating this practice’s development: the world sharing economy’s active position; tightened requirements for customers and a decline in bank loans; the lack of profitable lending programs for small and medium-sized entrepreneurship; the regulations of crowdfunding platforms introduced in 2020; citizens’ growing involvement in various IT platforms, including investment ones.

Published: December 2020

Abstract
The article deals with the problem of assessing the influence of the boundary conditions for fixing a plate with a welded seam on the stress-strain state during hardening with a ball-rod hardener. Welded joints are currently a trouble spot of the destruction of heavily loaded structures. Analysis of the microstructure and strength characteristics of the welded joint of 09G2S steel showed that in the fusion and heat-affected zones, the strength decreases due to temperature effects. The problem of modeling the strengthening of a welded joint with a ball-bar hardener under various conditions of plate fixing: with a free and fixed lower face is considered. The FEM model is constructed and the comparison of the conditions of plate fixation is carried out, which makes it possible to assess the degree of hardening and to assess the residual stresses after hardening treatment. It is shown that strengthening of a plate with a free bottom face significantly changes the stress-strain state of the plate and redistributes residual stresses to the weld zone, where strengthening is undesirable.

Authors: Babitskiy L , Belov A , Moskalevich V 
Published: December 2020

Abstract
It is proposed to introduce a mechanism with moving masses separated by elastic elements of different rigidity into the design scheme of the cultivator working body to ensure the self-oscillating resonant interaction of the cultivator claw with the soil. The frequencies of the main oscillations of the system with moving masses, corresponding to the range of oscillation frequencies of the cultivator claw in the soil, are determined using the oscillation theory. The oscillation frequency of the cultivator paw was determined experimentally in the soil channel. By calculation, using the obtained equations, the values of the moving masses and the rigidity of the elastic elements of the mechanism of self-oscillating vibro-impact interaction with the soil of the cultivator are found.

Published: December 2020

Abstract
The introduction of high-grade mineral additives in feed allows to get balanced rations for livestock and poultry. It is known that the most effective use of them when feeding in the composition of feed. However, today, in real conditions, farms receive less than 30% of the required amount of chemical feed additives with compound feed. In addition, the outlined tendency towards a decrease in the production of compound feed due to the lack of grain and protein components indicates that the feed industry is not entirely able to solve this problem. Adequate feeding of dairy cows assumes an optimal intake of all essential nutrients in the body, which contributes to good health, normal reproduction and high productivity. A significant reduction in the energy deficit during this period can be achieved by introducing energy-rich feed concentrates, grass cutting and grass flour of high quality, root crops, etc. into the diet. The higher the milk yield of cows, the more energy should be in one kilogram of dry matter of the diet. This article proposes a technology for producing a protein-vitamin feed concentrate for full-value feeding of farm animals. To solve the fodder problem in animal husbandry, it is necessary to more widely use substandard raw materials, organic waste, ensuring their utilization within the framework of waste-free technology.

Published: December 2020

Abstract
Measuring dimensions of indoor environment have an important role in construction, whether for calculation of work, or documentation purposes. Humans may introduce errors and make measuring real objects less accurate. Several methods have been developed to reduce this error and one of them is a non-contact measurement that executes according to guideline can minimize this error. Measurement using image-based measurement can reduce human involvement, where Total Station Theodolite (TST) is very dependent on its operator skill and involvement. This study aims to show the differences between image-based and laser-based measurements using TST in measuring the dimension of the indoor environment. Image-based measurement was obtained by taking photos of a few rooms and processed with an open-source software to produce a 3D model. This 3D model then measured to provide measurement for differences comparison. Laser-based measurement was obtained by hiring professional surveyor to measure the rooms with TST. Results from this study can be used as a reference in developing a new method to measure dimension in indoor application. Without hiring professional to measure using photogrammetry in this research, measurement using photogrammetry can get average differences of 0,2593% from measurement using TST.
