Boeing 787 Electrical System The mission of aviation explorers was very clear from day one: to keep on flying as far as one can go, keeping speed, and land at a point whose height is comparable to that of the takeoff and accompany oneself with one pilot. These were repeated by the Wright brothers, Orville and Wilbur Wright. The wrights achieved their mission when they got on air flying 852 feet (260 m) in 59 seconds in the year 1903. Since then, people’s expectations have continued to grow across the world and the development and the functions of the airplane continues to grow day by day. For instance, the Boeing 787 Dreamliner has a capacity of 290 passengers with a distance coverage of 500 nautical miles or 15,750 km, which is a third of…show more content…
What the Wright brothers needed for the first planes may not be even considered as the basics of the modern planes, which have become very sophisticated. The various systems have been engineered close to perfection to meet the modern day missions. Such systems include the highly sophisticated electrical systems that has transformed over the years from a single electric spark into highly engineered systems that make modern plane travel across the globe. The electrical system is one the fundamental systems in the modern design of the planes. It has several functions ranging from the production, controlling, and the distribution of power to other systems that require power. Such systems in need of power include flight controls, flight deck displays, in-flight entertainment, just to name a few. One fundamental difference between the electrical system in an airplane and other motion systems that require such a system is that it does not use on board battery power, but the plane electricity is generated during flight by generators on the…show more content…
The transmission of the power is from the generators through four alternating current (AC) buses to distribution channels where it is used as 235V AC, or converted to a form suitable for use by other systems. Other power sources for the Boeing 787 include the main battery, which is used in ground operations and braking; the APU battery that starts the APU; and ground power, which can connect through three power receptacles. In the unlikely event of power failure, the APU and the main battery and ram air turbine can act as system power backup during flight. The Boeing 787 has also incorporated a safety system that ensures that there is no greater risk that may be posed in case of electrical problems. For instance, the plane can fly and land safely on one engine and one of the six generators. Up to this point, it is clear that the significance of the electrical system cannot be over emphasized and, hence, the need for the continued research and development on the subject
