Experimental Investigation on Hybrid Propulsion Technology to Increase Fuel Efficiency and Reduce Carbon Emission

Abstract

Hybrid aircraft propulsion systems, is the combination of electrically driven fans and on-board battery storage, therecent studies show that there is more potential to reduce aircraft fuel consumption and emissions significantly. The main advantages of hybrid aircraft are fuel savings, lower carbon emissions, and reduction in noise level. Since the hybrid aircraft run on multiple power sources such as mechanical and electrical, flight sustainability can be improved in case of failure of individual parts in the propulsion system. Thus, an increase in flight safety can be another benefit of the hybrid-electric propulsion concept. The demand for non-renewable energy sources continually increases, and the energy source is exponential decreasing due to the increase in the automobiles. This paper demonstrates the overview of hybrid electric vehicles, its construction, design, and development on a small scale using the nitro fuelled piston engine (2 strokes) and integrated electric motor. This project mainly aims to develop a hybrid system on a small scale and implementing it on an RC aircraft to study the performance of thrust efficiency and carbon emission. This is done by developing a system that extracts energy from the engine, stores the energy, and transfers it to the electric motor and thereby producing additional thrust.
