According to a report published by the European Commission, the amount of greenhouse gas emissions from aircraft accounts for 3% of total greenhouse gas emissions in the countries of the European Union (EU). When we operate on a global scale, the amount of greenhouse gases emitted by aircraft accounts for 4% of total greenhouse gas emissions. By way of comparison, the emission values of a London-New York flight are roughly equivalent to the amount of heat produced by a person living in an EU country that heats the house all year
. Aviation is an undisguised percentage of greenhouse gas emissions around the world. At this point, the concept of "electric aviation" has begun to show its face. Electric aircraft will significantly reduce greenhouse gas emissions, leading to lower dangerous values. According to estimates, greenhouse gases will be released in 2030 by 40% below the 1990 level. The EU's target for 2050 is to reduce by 80% the emissions of greenhouse gases. greenhouse in 1990 …
The Challenges of Electric Aviation
The Electric Aviation, Future of Aviation There are very large distances to overcome. In 2012, an electric plane could reach a speed of 326 km / h while carrying a single passenger. Today, however, a Boeing 787 can reach 940 km / h and does so with more than 240 passengers. These figures illustrate in a striking way that electric aviation is far from conventional aviation. Forecasts indicate that until 2030 commercial aviation can not be done with electric motor or hybrid technology.
Battery Technology
The most important limiters of electric aviation are the batteries, not the design of the aircraft or the weight of the engines, but the batteries. At present, battery technology is far from meeting the power and weight requirements of electric aviation. Currently, a jet fuel produces 43 times more energy than a battery. Battery technology increases by 5% to 8% per year in energy intensity.
Electric aircraft begin to be produced
Boeing and JetBlue companies begin to invest in electric aircraft technology. Both companies have been investing in Zunum Aero since 2013 and are preparing for electric aviation. The company is working on a prototype that plans to fly with 12 passengers in 2020.
The Airbus company, in collaboration with Rolls-Royce and Siemens, is developing the Airbus E-Fan X. This prototype aircraft Electric has 2 electric motors powered by a lithium-ion battery technology, also used in smartphones. E-Fan X, which has a range of 60 minutes in 2014, will leave with a more advanced version in 2020.
An Israeli company called Eviation Aircraft is developing an electric plane called Eviation Alice . Work has been ongoing since 2015 and improvements are underway to bring out the first electric prototype. Apart from these initiatives, there are companies working hard for electric aviation like Wright Electric, Ampaire and Joby Aviation. Wright Electric is trying to design a commercial aircraft that can cover about 500 kilometers. The aim of Ampaire is to develop an aircraft with a capacity of 7-9 passengers and 160 km range for 2020. Joby Aviation has spent the last 10 years developing its own electric motors. The purpose of the company is to keep a 5-person aircraft in the air over 240 km
It seems that there will be a big difference of time between the electric cars that fill the streets and the sky of electric planes. Electric airplanes still have a long way to go, and for their transportation to be successful, batteries, engines and designs have to endure countless disabilities.
