Energy and Environmental Evaluation on LPG Transition for Piston Engine of the Plane

Sectoral pressures created by the awareness of global warming and climate change have made the control of emissions important in the aviation industry. Fuel preference is a priority issue, especially for fuel-based energy and environmental sustainability. Liquefied petroleum gas (LPG), a solution for land vehicles, may be a choice for aircraft using piston engines. In this study, first of all, performance analyses were made for one piston engines together with the current AVGAS consumption. Then, the performance effect of the engine due to LPG usage was examined. In this context, the environmental effects of engine performance changes are also discussed within the scope of entropy management. The review aircraft were compared at different altitudes and flight conditions. The analysis shows a 54.37% saving in LPG consumption due to classical consumption. At the end of the study, the sectoral use of LPG was evaluated.
