In modern times, it is believed that by reducing the risk of military intervention, military security has lost its relevance, and economic security has become a priority of national interests. The principle of economic security is as follows: national interests are supported through an economic system that supports free exchange and ensures the upward mobility of the nation. The analysis of economic security is based on the concept of national interests. It is well known that the problem of national security and its components cannot be considered only from the standpoint of current interests; it is closely related to the possibilities of their implementation over a significant, long-term period. Each stage of realization of national interests of the country is characterized by its assessment of its geopolitical, geostrategic and geoeconomic conditions, security threats and the main carriers of these threats, the mechanism of realization of national interests (each of the stages has its own assessment of the main definitions and categories of security, the main vectors of geoeconomic policy). Economic security is the foundation and material basis of national security. A state is in a state of security if it protects its own national interests and is able to defend them through political, economic, socio-psychological, military and other actions. There is a close connection between economic security and the system of national and state interests, and it is through this category that the problems of economic potential and economic power of the state, geopolitical and geoeconomic positions of the country in the modern world are intertwined. At a time when regional forces are trying to expand markets, provide access to finance and the latest technology, economic security has become a necessary component of the ability of regional forces to expand their influence. The article is devoted to the study of economic security of Ukraine and its components using the model of quantitative assessment of economic security of Ukraine. Using the Fishburne method, a model is built that allows to obtain an integrated assessment of the level of economic security based on the synthesis of nine partial indicators.

Thermal Stability Of

The propensity of aviation turbine fuels to produce deposits in the oil-cooler and filter sections of aircraft fuel systems has been examined using a rig that simulates the fuel system of an aircraft and which employs realistic flow rates. All the fuels examined were found to be thermally stable up to temperatures in excess of those currently attained in engine oil coolers. Comparison with results obtained with the JFTOT indicates that this is not suited for use as a research tool.

Abstract Stakeholders in the aviation industry committed to a goal of 50% reduction in carbon emissions by the year 2050, to be achieved by reducing emissions 1.5% each year from 2020 onwards. There are multiple pathways to achieve this goal however; with, the most promising technology being Sustainable Aviation Fuels (SAF), which are biofuels blended with kerosene. As the industry shifts towards SAF, it is important to evaluate these fuels in terms of their long-term sustainability, and this is the objective of the current study. Sixteen types of fuels were assessed which include fossil, natural gas, electric, and SAF. A Multi Criterion Decision Making methodology was adopted which considers three categories, namely environmental, economic, and social aspects which in turn are broken up into 8 indicators in all (such as ecological footprints, cost of transportation, investment cost, operating costs, employment generation, and health & safety). A Monte Carlo analysis was also performed to analyze sensitivity of the results to the weights attributed to the three categories. The most sustainable fuel was found to be Hydrogen, with a score of 0.91 out of 1.0. The least sustainable were determined to be the military kerosene-based fuels (with the experimental fuel JP-8 + 100LT being the poorest with a normalized score of 0.50).

Biodiesel Fuels

Biodiesel is an alternative fuel for diesel engines which doesn?t contain pollutants and sulfur; on the contrary it contains oxygen. In addition, both physical and chemical properties of sunflower oil methyl ester (SME) are identical to diesel fuel. Conversely, diesel and biodiesel fuels are widely used with some additives to reduce viscosity, increase the amount of cetane, and improve combustion efficiency. This study uses diesel fuel, SME and its mixture with aviation fuel JetA-1 which are widely used in the aviation industry. . Fuel mixtures were used in 1-cylinder, 4-stroke diesel engine under full load and variable engine speeds. In this experiment, engine performance and emission level are investigated. As a conclusion, as the JetA-1 ratio increases in the mixture, lower nitrogen oxide (NOx) emission is measured. Also, specific fuel consumption is lowered.

This article analyzes Japan’s Overseas Development Assistance (ODA) policy in Jordan, focusing primarily on the areas concerning security. After the oil shock in 1973, security concerns in the Middle East affected Japan’s economic security policy. However, Japan’s long vulnerability in energy supply was not the sole determinant of its aid policies in the Middle East. Rather, a paradigm shift in the Japanese government’s ODA policy in the 1990s, the implementation of the human security approach, had a greater impact than economic security in subsequent Japanese ODA programs in Jordan. Japan has given more assistance to areas relevant to military security in its ODA in Jordan, particularly after increasing security concerns about the Middle East since the early twenty-first century. The two phenomena—Japan’s more aggressive commitment in the Middle East, including its deployment of Japan Self-Defense Forces (JSDF) in the region and Jordan’s greater responsibility in regional security—occurred simultaneously because of a series of crises after 2003. The unusual nature of Jordanian society today, a small society that hosts refugees from many nations, means the new Japanese ODA approach in Jordan has more diverse recipients than ever, as the country is becoming a host for a community of refugees.

Performance Results

At present, nearly 100% of aviation fuel is derived from petroleum using conventional and well known refining technology. However, the fluctuations of the fuel price and the vulnerability of crude oil sources have increased the interest of aviation industry in alternate energy sources. The motivation of this interest is actually twofold: firstly alternative fuels will help to stabilize price fluctuations by relieving the world wide demand for conventional fuel. Secondly alternative fuels could provide environmental benefits including a substantial reduction of emitted CO2 over the fuel life cycle. Thus, the ideal alternative fuel will fulfil both requirements: relieve the demand for fuels derived from crude oil and significantly reduce CO2 emissions. In the present paper, the effects of various alternative fuels on the operation of a medium transport/utility helicopter are investigated using performance models of the helicopter and its associated turboshaft engine. These models are developed in an object-oriented simulation environment that allows a direct mechanical connection to be established between them in order to create an integrated model. Considering the case of a typical mission for the specific helicopter/engine combination, a comparative evaluation of conventional and alternative fuels is then carried out and performance results are presented at both engine and helicopter level.
