Over the last few weeks, there has been a lot of news about flying cars, air-taxis, and personal drones. Recently a variety of concept studies and prototypes was presented and they all immediately create the wish to own one of these so you can fly wherever you want, watching traffic jams from above. These pictures provoke two things: Make people dream and make great marketing for the creator of these images.
About a dozen companies around the world, including startups and giant aerospace manufacturers, are working on prototypes. Some of them use this vision of mobility for marketing purposes long before a prototype lifts off the ground, others quietly design a fully functioning platform able to take the world by storm. Regulatory issues, as well as issues in acceptance and privacy, are roadblocks on the way to adoption. Lawmakers must react soon as the pressure towards faster and more economic transport grows.
The chart below shows some of the current air-taxi projects, capabilities and individual progress. In general, the next five to 10 years are going to an incredible time for the roll-out of this technology.
A lot of these concepts are multirotor-based drone-like concepts and spot-on to the current Zeitgeist. Aeromobils “Flying Car” and Terrafugias “Transition” however have folding wings and therefore require a runway to take off and land. This set-up allows covering large distances much more efficient than (multi-)rotor configurations.
German manufacturer e-volo showed automated operation years ago and has certified prototypes allowing passengers to fly to date. In early 2016 EHANG presented the 184 concept at CES in Las Vegas, Nevada and a flying (unmanned) prototype in late December. This Autonomous Aerial Vehicle (AAV) requires no pilot and can be controlled via mobile phone app. EHANG is planning the entry-into-service in Dubai this summer.
Being able to vertically take-off and land (VTOL) has massive advantages especially when it comes to urban mobility. Efficient usage of air-taxis, however, starts at a flight distance of around 10 miles (~6,3 kilometers) favoring a fixed-wing configuration.
Why not both? Using multiple engines to lift up a platform vertically and an additional one to push you forward can be seen in the “separate lift thrust” configurations of Aurora Flight Systems’ “eVTOL” and the yet top-secret Zee.Aero platform. A vertical to horizontal flight transition can also be done by turning the engines from vertical to a horizontal position (tilt-rotor/tilt-wing configuration). This can be seen at Moller Internationals “Skycar”, Airbus’ “Vahana”, Joby Aviations’ “S2” or the very recently introduced Lilium platform equipped with 32 tilt-rotor engines.
Earlier this week, the Uber Elevate Summit explained this future ecosystem and Uber’s approach to zero in on questions like: hub location, hub size, hub occupation, load factor (butts in seats), flight time, airspace separation, minimum ground time, charging time, passenger capacity, platform size and many more.
The good news is they can do all of this with real user data, which is collected by their car-hailing service. This will allow the company to start offering Uber Elevate on frequented routes, providing passengers a minimum time-saving of 40% of the usual trip time. The Uber Elevate Network will be tested in Dallas and Dubai starting in 2020.
