Electrification of aircraft

  1. 1. Electrification of aircraft Why try to electrify aircraft? How could we electrify aircraft? Challenges Aviation worldwide uses more than 5000 barrels of fuel per day* Noise Pollution Environmental Full electrification would almost completely eliminate noise pollution, partial electrification (hybrid) would drastically reduce noise. Allowing runways near residential areas to be used for longer hours and open up additional locations for new runways. Estimated to run out of fossil fuels within the next 50-100 years Improved air quality Turboshaft Fuel Generator Power electronics Electric Bus Motor(s) Aircraft systems Battery Turboshaft Fuel Battery Generator Electric Bus Motor(s) Aircraft systems Power electronics Battery Electric Bus Motor(s) Aircraft systems Power electronics Turboshaft Fuel Generator Power electronics Electric Bus Motor(s) Aircraft systems Battery Turboshaft Fuel Battery Generator Electric Bus Motor(s) Aircraft systems Power electronics Battery Electric Bus Motor(s) Aircraft systems Power electronics FULL HYBRID ALL ELECTRIC Turboshaft Fuel Generator Power electronics Electric Bus Motor(s) Aircraft systems Battery Turboshaft Fuel Battery Generator Electric Bus Motor(s) Aircraft systems Power electronics Battery Electric Bus Motor(s) Aircraft systems Power electronics MORE ELECTRIC HYBRID Weight – weight to energy ratio of kerosene currently far more efficient than batteries Larger corporations err on the side of caution – whilst smaller organisations tend to be more optimistic. Transforming aerospace engineering for faster design, reduced downtime and lower costs.

Extensive testing is required before commercial flights can begin Charging – where will they charge? How long will batteries take to charge? What happens when flights are diverted? * Indexmundi.com 15kg 20kg ? NOX O3 CO2 PM2.5 20-30 years? 10-20 years? We can’t be sure when we’ll all be able to enjoy electric powered flights, but its benefits mean that one day we will.
