ТЕХНОЛОГИЯ ПРИГОТОВЛЕНИЯ И ПОДАЧИ КОМПЛЕКСНОГО ТОПЛИВА ДЛЯ УЛУЧШЕНИЯ ЭКСПЛУАТАЦИОННО-ТЕХНИЧЕСКИХ ХАРАКТЕРИСТИК ДИЗЕЛЬНЫХ ДВИГАТЕЛЕЙ АВТОТРАКТОРНОЙ ТЕХНИКИ

The technology of preparation and supply of complex fuel is proposed to improve the operational and technical characteristics of diesel engines of automotive equipment, as well as technical means for its implementation. The analysis of the work of the ATT samples showed that its operation occurs with low speeds in the field and heavy loads on the internal combustion engine (ICE), while its thermal tension increases and the combustion process worsens in the combustion chamber, leading to the formation of carbon deposits. To solve this problem, a method and technical means are proposed for cleaning engine parts from the formed carbon deposits without parsing it during daily operation in order to improve the operational and technical characteristics of equipment, on which the readiness of samples of the machine and tractor fleet will directly depend. The developed method is based on direct mixing of fuel with water, dispersion of the resulting mixture and feeding into the combustion chamber of the internal combustion engine when the fuel temperature exceeds a given value, and depending on the temperature, as well as the number of revolutions of the internal combustion engine and from different levels of the mixing tank. The versatility of the developed devices for the implementation of the proposed method is that they can be used not only in stationary conditions, but also on board the equipment during its operation. The implementation of the developed method and technical devices will ensure effective removal of carbon deposits due to the interaction of red-hot carbon particles with water droplets (steam), which will lead to an increase in the resource of diesel internal combustion engines, restoration of operational and technical characteristics of especially worn-out diesel internal combustion engines and ultimately increase the readiness of individual samples of ATT and, in general, the technical readiness of the machine and tractor fleet.

The transition to a zero-carbon energy system is inevitable if society is to negate CO2 emissions associated causes of Climate Change and replace the usage of our finite hydrocarbon resources. The transition to a zero-carbon energy system will take decades to not only replicate the scale and efficiency of our existing energy system but to also develop the technologies needed that on a like for like basis will provide society with at least comparing with today a zero-carbon energy system that is efficient and cost effective. This short communication puts forward a potential solution that is efficient, cost effective and most importantly zero-carbon emissions. The intent is to give an overview of the technologies that can achieve this with their respective current technical readiness and timeline to full scale public deployment.

Stratospheric-trace-gas-profile retrievals from balloon-borne limb imaging of mid-infrared emission spectra

Abstract. The Limb Imaging Fourier Transform Spectrometer Experiment (LIFE) instrument is a balloon-borne prototype of a satellite instrument designed to take vertical images of atmospheric limb emission spectra in the 700–1400 cm−1 wavenumber range from the upper-troposphere–lower-stratosphere (UTLS) altitude region of the atmosphere. The prototype builds on the success of past and existing instruments while reducing the complexity of the imaging design. This paper details the results of a demonstration flight on a stabilized stratospheric balloon gondola from Timmins, Canada, in August 2019. Retrievals of vertical trace gas profiles for the important greenhouse gases H2O, O3, CH4, and N2O, as well as HNO3, are performed using an optimal estimation approach and the SASKTRAN radiative transfer model. The retrieved profiles are compared to approximately coincident observations made by the Atmospheric Chemistry Experiment Fourier Transform Spectrometer (ACE-FTS) solar occultation and Microwave Limb Sounder (MLS) instruments. An evaluation of the LIFE measurements is performed, and areas of improvement are identified. This work increases the overall technical readiness of the approach for future balloon, aircraft, and space applications.

TECHNICAL PREPAREDNESS OF UKRAINIAN HIGH JUMPER

During 1990–2022, Ukraine was successfully represented at the Olympic Games, World and European Championships by high jumpers: Inga Babakova, Vita Stepina, Vita Palamar, Iryna Mykhalchenko, Yaroslava Maguchykh, Yulia Levchenko, Iryna Gerashchenko, Oksana Yukuneva, Kateryna Tabashnik, Yulia Chumachenko and other. The aim of the work: to improve information on the peculiarities of technical readiness of Ukrainian high jumpers. Task: investigate the indicators of technical readiness of Ukrainian high jumpers according to the time characteristics of the technique of takeoff, repulsion, and flight over the bar. Methods: we conducted pedagogical observation of high jump at the Ukrainian Athletics Championships in 2009, 2018, the Cups of Ukraine in 2011, 2012, and the All-Ukrainian High Jump Competition "Memorial of Oleksiy Demyanyuk" in 2020 with the help of video recording (Sony HDR-PJ50E video camera). All videos were analyzed using the program - Tracker - 4.87. The following time characteristics of technical readiness are determined: duration of reference, flight, periods of all take-off steps, duration of repulsion, and flight through the bar. Indicators were calculated: the rate of all take-off steps, the contrast of the growth rate, the rate intensity, the rate mobilization, the coefficients of activity of the take-off steps, and the activity of the passage through the swing leg. Results and conclusions: new data were obtained on the duration of reference and flight periods of all steps of the ten leading jumps of Ukraine. The data of scientific and methodical literature on quantitative characteristics of technical readiness (rate of the third, penultimate, and last run steps, activity coefficient of the last run step, and duration of repulsion) in highly qualified high jumpers are confirmed. Despite the density of the results of the high jump, as the best result and the result during the observation, the jumps differ significantly in terms of contrasts: the growth rate of the last steps of the run, rate mobilization, and the activity of the passage through the swing leg in the last step.

Capability demonstration of a 3D CdZnTe detector on a high-altitude balloon flight

In collaboration between the University of Michigan and Los Alamos National Laboratory, a 3D position-sensing CdZnTe (CZT) detector prototype was built and integrated into a high-altitude balloon platform to evaluate its performance in a space-like mixed-radiation environment. The detector prototype, Orion Eagle, was designed to operate in near-vacuum environments without any temperature regulation. Orion Eagle was hand-launched from NASA’s Columbia Scientific Balloon Facility (CSBF) at Fort Sumner, NM on September 26, 2021, and successfully operated throughout a 9-hour flight, which reached 38.5 km in altitude. The flight met its objectives, successfully detecting atmospheric gamma rays and galactic cosmic rays, and raising the Technical Readiness Level from 4 to 6 for large-volume 3D CZT detector technology for space applications. Ionization tracks produced by charged particles create spatial signatures in the detector that are distinguishable from discrete gamma-ray interactions. Therefore, the 3D position-sensing capabilities using pixelated electrodes on a CZT detector can help enable discrimination of background charged particles from gamma-ray events without an anticoincidence shield. The potential for background rejection capability, ambient-temperature operation, gamma-ray coded-aperture and Compton imaging, and near High Purity Germanium (HPGe) energy resolution motivate the use of large-volume 3D CZT imaging spectrometers in future space missions.

КОРРЕКТИРОВАНИЕ ПЕРИОДИЧНОСТИ ОПЕРАЦИЙ ТЕХНИЧЕСКОГО СЕРВИСА МОБИЛЬНЫХ МАШИН С УЧЕТОМ ЖЕСТКОСТИ КЛИМАТА

Based on the analysis of the main operational factors, among which, for specific areas of equipment supply, one of the main ones is the climatic factor, as well as the main damaging degradation processes during the operation of machines, an effective mechanism for planning the frequency of maintenance operations is proposed, which helps to ensure a high level of technical readiness of machines. The operability potential was analyzed, its active, reserve and passive parts were considered, which made it possible to present a model for changing and restoring the operability potential of a mobile machine. Mathematical dependences are given for certain models of machines of the same functional purpose, as well as characterizing processes of reducing the potential of their performance in a certain external environment, their transformation is noted when changing natural and climatic operating conditions. The construction of a priori diagram of the ranks of climatic factors made it possible to note that the most significant adverse effect is exerted by temperature, humidity and solar radiation in the operating area. Taking into account the distribution of zones of technical rigidity of the climate, its score and the coefficient of continentality, a method is proposed for correcting the frequency of operations of technical service of transport-technological machines for the zone of their actual operation.

Technical and economic assessment of maintenance and repair systems of agricultural machinery

Relevance. The efficiency of agricultural production largely depends on the technical condition of the agricultural machinery fleet. The technical condition, in turn, depends on many factors that determine the level of operation of the equipment. One of the most important factors determining the reliability of agricultural machinery, the cost of restoring and maintaining the working condition of agricultural machinery is the frequency of maintenance. As a result of studies conducted in the agricultural organizations of the region, it was revealed that engineering and technical services, when organizing maintenance and repair (TO and R), use canceled GOST, referring to the fact that domestic equipment, its reliability and performance are not able to recover when frequency of 125 hours. Therefore, the purpose of this study is to determine the effect of the frequency of maintenance and repair on the preservation of the resource and the indicator of the rate of change of the resource, on the performance of the machine-tractor unit (MTA), on fuel consumption, on the costs of restoring and maintaining the working condition of agricultural tractors.Methods. The following methods were used in the study: normative, statistical, expert assessments, experimental, calculation-constructive, economic-mathematical methods. For the economic justification of the periodicity of technical impacts of agricultural machinery, statistical data from agricultural organizations were used, GOST regulating the maintenance and repair of agricultural machinery were used.Results. The maintenance and repair system, regulated by GOST 20793-2009, meets the requirements of technical and production operation of tractors. Traction properties of tractors are higher by 0.7%, specific fuel consumption during agricultural technological operations is lower by 0.5%, labor costs for maintaining and restoring technical readiness are lower by 13.8%.

ТРУДОЕМКОСТЬ РЕМОНТНЫХ РАБОТ ПРИ ВОССТАНОВЛЕНИИ ТЕХНИКИ

The management of the technical condition of the machine and tractor fleet, in order to ensure its sufficient performance and serviceability, is proposed to be implemented on the basis of a scientifically based system for the repair of automotive equipment (AT). The production capabilities of the repair body, which is part of the maintenance and repair (M&R) system of the enterprise, for the restoration of failed equipment are determined by theoretical calculation in such a way that the repair body is able to repair faulty equipment as soon as possible and in full. The method of the theory of queuing, which details the calculation of the criteria for the repair system of an enterprise, is proposed. Two methods for calculating the labor intensity of repair work during the restoration of AT, which make it possible to determine the necessary performance of the repair body in order to provide a given coefficient of technical readiness of the enterprise's fleet of vehicles, are considered. The joint implementation of the developed methods will expand the capabilities of the enterprise repair system, for the timely restoration of AT, depending on the number of failed AT, as well as develop theoretical foundations and practical recommendations that will provide the management of enterprises and their repair bodies with the ability to solve various problems. They will allow, according to the data on the failed equipment, to determine the required number and composition of repair teams, the data on which will make it possible to determine the capabilities of the repair body to restore equipment for various periods of time. Based on the data on the number of repair teams, their composition, and the existing failure of equipment, it is supposed to determine the time during which it will be restored. Based on the data on the number of equipment to be repaired and the desired duration of the work, it is supposed to determine the required number and composition of repair teams for its restoration; optimal conditions when it is rational to transport equipment to a repair body, or, conversely, a repair team to the parking lot of a failed sample; determine the composition of the technical means required for the repair work.

МЕТОДИКА ОБОСНОВАНИЯ СТРУКТУРЫ И ХАРАКТЕРИСТИК СИСТЕМЫ РЕМОНТНО-ОБСЛУЖИВАЮЩЕЙ БАЗЫ, ОБЕСПЕЧИВАЮЩЕЙ РАБОТОСПОСОБНОСТЬ СОВРЕМЕННОЙ ТЕХНИКИ

The effective operation of the machine and tractor fleet (MTF) of a modern agro-industrial complex requires monitoring of its technical condition by a system of repair and maintenance bases (RMB). A methodology for substantiating the structure and characteristics of the ROB system using special decision support systems (SDSS) is proposed, which will make it possible to implement the maintenance strategy “by actual state”, as well as reduce the recovery time of the MTF. The methodology includes a set of interrelated models: forecasting and diagnosing the technical condition of the MTF, the functioning of the system for ensuring the operability of the MTP and the formation of cost dependencies on the functioning of the RMB system. Algorithms were applied: redistribution of costs between maintenance activities (TO) and current repairs (TR); solution of the optimization problem based on the modified Nelder-Mead method. It was revealed that the small value of the maintenance interval allows to achieve sufficiently high values for the coefficient of technical readiness (Kg). It is shown that the main measure that allows to reduce operating costs and positively influence the value of Kg is the rational distribution of time for carrying out checks used during maintenance of the MTF sample. The use of 2-6 specialists makes it possible to ensure the duration of maintenance according to the state of the ICC unit from two to four hours. Deviations of more than 30 minutes at TR from the normative values of the recovery time led to a sharp decrease in the level of availability at the current level of the sudden failure flow parameter. Attracting an average of 3 - 4 specialists is required to complete the TR. It has been established that the main condition for the optimal operation of the MTF sample is individual monitoring of its technical condition, which makes it possible to reduce the duration of adjustment and repair measures by 40%. The condition for the effectiveness of the RMB system is the presence of at least four people of engineering and technical staff in the teams that carry out these activities. The total cost reduction for ensuring the working condition of the studied equipment was about 18 - 20%.

Intelligent fault diagnosis of turbine blade cracks via multiscale sparse filtering and multi-kernel support vector machine for information fusion

For accurately identifying the crack severity of turbine blades, a novel intelligent diagnosis framework is proposed in our paper, which uses multiscale sparse filtering (MSF)-based unsupervised sparse feature learning and multi-kernel support vector machine for information fusion (MKSVMIF). To realize the technical readiness and the state-of-the-art diagnostic performance, advanced signal processing methods are used to eliminate interference and retain fault-related characteristics. Thus, the EEMD-based multiwavelet packet energy entropy (EEMD-WPEE) as an enhanced method is proposed for multi-source three-dimensional blade tip clearance signals (3D-BTC), which is used to enhance the fault-related information. Afterward, the MSF is constructed to adaptively learn multisource sparse features from EEMD-WPEE representation of 3D-BTC by an unsupervised manner. Finally, the MKSVMIF is proposed to fuse these sparse features and diagnose crack severities. To validate the effectiveness of our proposed MSF-MKSVMIF framework, Extensive experiments are conducted on a blade-rotor simulation rig, and the results show that our proposed framework is superior to other comparison methods and can quantitatively detect different blade crack severities with a relatively small number of samples.

Are Countries Ready for REDD+ Payments? REDD+ Readiness in Bhutan, India, Myanmar, and Nepal

The Paris Agreement recognized the significant role of forests in climate change mitigating and adapting. It also emphasized the importance of the Reducing Emissions from Deforestation and forest Degradation (REDD+) mechanism as a vital tool for achieving the goal of limiting global warming to 1.5 °C above pre-industrial levels. This study aims to assess the REDD+ readiness of Bhutan, India, Myanmar, and Nepal in preparation for effectively implementing REDD+ at the national level. A total of 57 indicators across five categories were used to evaluate readiness: overall readiness, technical readiness, institutional readiness, financing readiness, and strategy and safeguard readiness. The indicator-based questionnaire was administered to government officials, NGOs, private sectors, and academics. The results showed that Nepal was slightly more advanced in overall readiness, owing in part to the longer readiness period of the World Bank-supported Terai Arc ER-P. India scored highly in technical readiness and has several sub-national programmes for REDD+ implementation. Bhutan had strong ratings for strategy and safeguard readiness but lower scores for institutional and financing readiness. Myanmar had consistent ratings across readiness areas, but a lower score for technical readiness. However, political and governance situations pose significant challenges to the effective implementation of REDD+ in Myanmar.
