Aug 29, 2016 Graham Warwick | Aviation Week & Space Technology

With its first regulation allowing routine use of unmanned aircraft systems (UAS) in national airspace now in place, the FAA is moving ahead with its next rulemaking actions to expand beyond the initial strict limitations placed on drone use. Ahead of the Part 107 Small UAS Rule taking effect on Aug.. 29, more than 20,000 commercial drones had been preregistered with the FAA, and more than 3,350 people had prebooked to take the knowledge test for a UAS operator’s certificate

Flight on demand is around the corner, and with it a radical reduction in the cost of getting from here to there. Cost in terms of out of pocket costs, but also in terms of speed, resource use and energy use.

The average automobile mileage today is 34.2 miles per gallon. Now a gallon of petrol contains 131,760,000 Joules. Dividing this by 34.2 miles is 3.85 megajoules per mile. 111.6 megajoules per day. A little less than a gallon per day.

The E-Fan has two 30 kW motors that are infinitely throttable. The aircraft uses 60 kW at take off and climb and at cruise it uses 42 kW. At speed it travels as 137 mph. Now 42 kW x 3600 seconds = 151,200,000 Joules per hour. Dividing this by 137 miles per hour obtains 1.10 megajoules per mile.

The E-fan has a specific fuel consumption 28.6% that of the average motorcar.
