Possibilities of Using Bioethanol as an Alternative Fuel in the Conditions of Jet Engines

Abstract

In today’s world, reducing the ecological impact of transport on the environment plays a key role in air transport, as a major polluter of the environment. The rate of use of solid fuels is a current parameter in the process of using renewable energy sources as well as reducing emissions from combustion engines. The article focuses on the use of bioethanol as an alternative fuel in aircraft engines, specifically in pulsejet engines. The partial goal of the manuscript was to create a functional measuring bench, which was equipped with pulsejet engine, sensors equipment and control unit. The manuscript mentions the use of a pulsed Lockwood-Hiller engine type, which was operated with three types of fuels (Gas N-95, Diesel and JET-A1 Kerosene) compared to bioethanol. The results of the experiments demonstrated the possibilities of using alternative fuels and their specific properties compared to conventional fuels and the possibility of implementation into real operation. It was the unique combustion processes of pulse engines that enabled the study at the border of the continuous and cyclic combustion process and the usability of bioethanol for aircraft engines. With regard to fuel use, it is assumed that alternative fuels will be a way to reduce the impact of aviation emissions and, in particular, to make more efficient use of renewable fuel sources.
