Electric aircraft
Summary
An electric aircraft is an aircraft powered by electricity.
Electric aircraft are seen as a way to reduce the environmental effects of aviation, providing zero emissions and quieter flights.
Electricity may be supplied by a variety of methods, the most common being batteries.
Most have electric motors driving propellers or turbines.
Crewed flights in an electrically powered airship go back to the 19th century, and to 1917 for a tethered helicopter.
Electrically powered model aircraft have been flown at least since 1957, preceding the small unmanned aerial vehicles (UAV) or drones used today. Small UAS could be used for parcel deliveries, and larger ones for long-endurance applications: aerial imagery, surveillance, telecommunications.
The first crewed free flight by an electrically powered aeroplane, the MB-E1, was made in 1973, and most crewed electric aircraft today are still only experimental prototypes.
Between 2015 and 2016, Solar Impulse 2 completed a circumnavigation
