Study of the effects of hybrid propulsion systems on optimum range

Demand for aviation is constantly increasing, presenting challenges in terms of fuel consumption, environmental impact and operational efficiency. The COVID-19 pandemic has further highlighted the need for sustainable solutions in the aviation industry. As a solution to these problems, hybrid electric drive systems have emerged as a promising technology. Hybrid electric propulsion systems have the potential to increase aircraft performance and reduce environmental impact. This thesis investigates the effects of hybrid electric propulsion systems on optimum aircraft range. The study examined the environmental impacts of aviation, various hybrid aircraft prototypes, and challenges associated with battery capacity and density. As the weight of the aircraft increases, fuel consumption also increases. This therefore means lower range. In current technology, in addition to the additional weight brought by batteries used in energy storage in hybrid drive systems, there are low battery densities and low battery capacity. When the studies were examined, it was seen that overcoming these restrictions was easier for small aircraft and more difficult for large aircraft. As a result of the studies and research carried out, the development of light and reliable batteries with high energy density and capacity will increase the range of hybrid aircraft and enable them to be used more efficiently at long ranges.
