Research Papers for More Electric and All Electric Aircraft

History knows much more cases, where people have died and aircrafts have been lost, due to disabled flight controls. It is very challenging job for aircraft manufacturing agencies to detect the cause of loss after damage of whole aircraft. Results shows, that most of the aircraft accidents caused due to the loss of hydraulic fluid. Today, most of the hydraulic lines are damaged, all actuators are not provided with hydraulic power, so surfaces cannot be moved. Hydraulic system are replaced with PBW system, in both accident access, crew now somewhat being able to control remaining flight control surfaces, which were intact. Even damage to all electric channels on one surface, will not lead to total loss of control of the remaining flight control surfaces. This is because current cannot drain away from aircraft, like hydraulic fluid. By analyzing aircraft accident, it can be said, that PBW system is safer when impossible things happen, like loss of all power supply channels. This makes us to move forward towards more fuel efficient plane or more electric aircrafts in future. Over the past years various industries are looking for renewable sources. If we have reasonable way of storing cost effectively and efficiently, this energy stored dilemma is lowing our adoption of renewable energy. Aviation industry is one of the most apparent to see. As we all know, we are going in a world of pushing electric vehicles and solar powered homes, yet everytime when we launch it burns 147 tons of fossil fuels. Boeing and Airbus are in constant battle of creating fuel efficient plane allowing customers to save ever increasing fuel cost. Yet they still use kerosene. This paper is comparative literature review of analyzing some potential problem with PBW technology focusing in terms of critical flight control with designing a methodology of all electric and more electric control system for various applications including flight-critical applications.
