More Electric Aircraft for Greener Aviation (A Comparative Study)

Ayush Pathak

Climate change is a grave concern, and contribution of the airline industry due to air pollution, noise pollution and heavy consumption of fossil fuel cannot be ignored. For a sustainable future, the airline industry needs to shift towards cleaner, more efficient aircraft. In order to reduce dependency on conventional sources of energy such as oil,electrical energy utilization, such as in Electric Vehicle, is being motivated today. One such step towards building a more environment-friendly aircraft is More Electric Air-craft (MEA), which replaces traditional hydraulic and pneumatic systems by an electrical system with help of power electronic devices so that air-crafts can reduce fuel consumption and generate more thrust while carrying the same or more, number of passengers/amount of freight. This paper discusses the working system of More Electric Air-craft and a comparative study with conventional aircraft system and how MEA can play a substantial role in conserving the environment and reduce the emission of greenhouse gases and heat by increasing fuel efficiency. Potential possibilities for future and trends are also discussed.
