This article presents the results of theoretical research in the field of methods for determining the forces arising in the traction return ropes of the balloon system used in transport, cargo and construction works. The emphasis is placed on the accuracy of the swivel positioning when exposed to a wind flow on the balloon. Theoretical calculations of the main parameters are given, such as: high-speed head, resultant lifting force, rope span, rope force, rope deflection, swivel movement and others. A technique is proposed that allows for a relatively simple and rapid calculation of rope forces in the process of performing cargo operations by an aerostat crane on a construction and installation site.

The process of creating an aggregated digital twin for a physical prototype of a manipulator with a load-gripping mechanism is considered. To solve the problem of controlling the system nodes, the freely distributed software platform Robot Operating System (ROS) was used, in particular, the MoveIt packages for manipulator control, OpenCV for computer vision and RViz for visualization. A description of the physical prototype and the stages of creating a model of the robotic complex in the form of URDF files is given. The developed system creates a level of abstraction between hardware and software, which allows exploring new technological solutions in the field of automation of processes of transport and cargo systems.

The paper considers the possibility of using waste from the forest industry, construction waste and ash and slag waste from boiler heating as a basis for the creation of biofertilizers and components that improve the structure of heavy soils. The analysis of experience on the impact of crushed bricks, coniferous and leaf litter with the inclusion of wood components, and ash and slag waste of boiler heating on the growth functions of red clover and watercress over various time intervals is presented. The possibility of using the presented waste in the process of self-infestation of territories is considered. A number of experiments have been conducted to identify the phytotoxic effect, as well as the reaction of general inhibition or stimulation of growth indicators of higher plants when used as a substrate in pure form, or a mixture with natural soil, wood components, samples of ash and slag waste of various shelf life, brick fighting.

The paper considers the possibility of using forest industry waste as a basis for the creation of biofertilizers. Of the main types of waste, sawdust, wood chips and bark are the most discussed. Taking into account the minimal change in composition, they can be used for the production of biofuels, such as pellets or briquettes. In addition, they can be used for the production of compost and fertilizers. The review of patents with a brief description of the method of processing and use of wood waste in the field of biotechnology is given The most promising for today can be considered the use of these wastes for the production of biofertilizers (when enriched with microbiological crops, as well as in the mixed part with animal husbandry and crop production waste), as well as the possibility of recultivation of disturbed areas during logging.

The article outlines the features of the developed algorithm for controlling autonomous industrial forest management facilities under real operating conditions under the forest canopy. A significant challenge faced by the developers in the presented algorithm was the practical absence of global navigation in the areas of use of potential autonomous industrial forest management objects. Thus the only alternative was local positioning algorithms, which of the existing ones were also unserviceable under real forest canopy conditions. The problem was exacerbated by the high requirements for positioning accuracy not so much for autonomous objects as for positioning accuracy relative to the object of work of the contact elements of technological equipment directly implementing the operations of the industrial timber harvesting process. The developed concept of local positioning has no analogues in the world, belongs to the algorithms of the latest generation, created by the authors on the basis of mathematical modelling of the operations of industrial forestry process and implemented in registered software complexes to manage the information flows that ensure the sustainable functioning of autonomous objects of industrial forestry in real operating conditions.

The article considers aspects of industrial forest management based on automation of control of local positioning, engineering and information technology of unmanned industry. Original algorithms for automatic control of unmanned technical systems and contact elements of technological equipment under the forest canopy, directly implementing the operations of the technological process, have been created and tested. Software complexes for data collection and control of information flows, providing stable functioning of the last generation local positioning means, have been developed and registered. The designs, methods and architecture of unmanned ground, suspended and airborne systems for industrial forest management, forest maintenance, located in specially protected natural areas and industries indirectly related to forest or forest land have been proposed.

This article presents the results of studies on the possible use of hoisting-and-transport rope complexes in the aftermath of emergency and environmental situations. The advantages of using self-propelled transport and freight carriages based on soft pneumatic bearings for rescue operations are considered. An algorithm is described for a software package designed to automate the process control of a freight-carriage used to lift and move cargo at predetermined coordinates.

In clause the opportunity of use balloon cable system descent to transport operations in remote mountain conditions is described. Dependence of system on wind influences is reflected. Proceeding from this, the design procedure of dynamic pressure which arise in the top suspension bracket of system is resulted, in view of mobility of a balloon under action of a wind.
