An innovative method for exhaust gases toxicity evaluation in the miniature turbojet engine

Abstract

Purpose The purpose of this paper is to present an assessment method of the toxicity emission evaluation during combustion in the miniature turbojet engine. Design/methodology/approach A small-scale turbojet engine was used for the research because measurements on real aircraft turbines are complex and expensive. The experiment was performed in accordance with innovative BAT – CELL Bio – Ambient Cell method which consists of determination of virtual toxic impact of the gas mixture on the living cells; it is therefore a direct method. The most significant innovation of this method is that, during the test, which consists of exposing the cells to the gas mixture, the cells are deprived of culture fluid. Findings The preliminary analysis shows that the method used here allows to determine the virtual impact of the gases on the human respiratory system and skin. It could be useful in defining the arduousness of an airport. The obtained results show that both of exhaust gases represent similar toxicity. Practical implications The new in vitro method allows to determine the virtual impact of the gases on the human respiratory system and skin. Significant potential for further research not only on the miniaturised engines, but also in the case of real objects, as this method does not have to be performed in a laboratory. Originality/value The work presents potential application of the innovatory method for exhaust gases toxicity evaluation in jet engines, which could be useful in defining the arduousness of an airport.

Combustion and Emissions Characteristics of the Turbine Engine Fueled with HEFA Blends from Different Feedstocks

“…The miniature turbojet engine GTM-140 is used not only in aviation alternative fuels research area but also for emission toxicity tests. The results of the preliminary studies were presented by Gawron et al [30,31] and Janicka et al [32].…”

Performance and Emissions of a Microturbine and Turbofan Powered by Alternative Fuels

“…After many years, the introduction of new rules for the certification of aircraft engines by ICAO (International Civil Aviation Organization) began, which is associated with the use of a new measurement methodology, which has been proposed in publications over the past years [6]. Recent research efforts [7] are aimed at measuring gaseous and particulate emissions under real conditions and better understanding their toxicity and impact on health [8][9][10].…”

Application of bat-cell bio-ambient tests in exhaust gas emissions examinations for Euro 4 and Euro 6 combustion engines

“…The vehicles were propelled with gasoline engines, had a valid periodical inspection and were therefore deemed fit and authorized for traffic. The research was carried out using the innovative method of direct toxicity assessment of BAT-CELL Bio-Ambient Tests, based on In vitro tests [7,8].…”
