Using Oil And Its Byproducts

INTRODUCTION
Throughout the years mankind has been using oil and its byproducts as a means of propulsion. However, we live in a world of finite resources and as oil is depleting it is necessary to find different resources. Using electricity as means of propulsion instead of internal combustion engines which is the current trend in most mechanical applications such as those in cars, ships and airplanes is what the world has deemed to be a solution to the over use of oil and its byproducts. Electricity is a resource which is significantly cleaner to the environment than that of oil, especially if generated by “green” means such as solar power, wind energy, etc.
With this concept in mind, airplanes, which provide a means of transportation,

THE MORE ELECTRIC AIRCRAFT
The more electric aircraft (MEA) is a concept which describes the use of electronics in the existing airplane designs. As per (Kostakis, et al., 2014) cabin pressurization, air-conditioning and anti-ice wing protection require pneumatic power, flight surface actuation, landing gear and breaking require hydraulic power, and finally, engine fuel and oil pumps require mechanical power. Electrical power is limited to cabin lights, fans and avionics. However, on a MEA electrical power is used to power some or all the above mentioned loads. Additionally, two new technological features are incorporated on a MEA, the bleed-less engine and the electrical self-start of the engine. In a bleed-less engine, all of the air-intake is converted into thrust, without it having to be bypassed away from the compressors, as it would in a conventional engine, to power pneumatic loads. Bleed air is still required on the engine for operability reasons, but by reducing the amount of bleed-air required, this could allow the removal of some heavy equipment such as fans and ducts, and provides potential improvements in engine reliability. This architectural shift has brought benefits such as weight reduction, optimized performance and reduced life-cycle costs for the plane operator. Nonetheless, the increase in on-board electrical energy
