At first glance, human-carrying drones sound no more _17_ t

9、han flying cars. Until recently. inventors had never been able to _18_ automobiles and aircraft in a practical way. Yet a few companies have kept at it: Woburn, for example, has since 2006 been developing Transition, a “roadable aircraft” that _19_ a small airplane that can fold its wings and drive

10、on roads. A personal flying car in every garage has proved to be a(n) _20_ sell, however, as there are serious safety concerns about asking the average commuter to train for a pilots license and take to the skies. Passenger drones, _21_, would operate autonomously and leave the “roadable” part behin

11、d in favor of larger versions of aircraft that already exist. Passenger drone designs favor distributed electric propulsion (推进), meaning instead of one large motor powered by a large engine they have multiple propellers each powered by its own, smaller motor. This _22_ lifting power and flight perf

12、ormance in exchange for mechanical simplicity and lighter weightfactors that could make them cheaper to operate. Quieter electric power would make the noise _23_ to city residents, although it remains to be seen how much weight such a vehicle could lift, and for how long. With any of these vehicles,

13、 safety is the biggest concern and _24_ to both the aircraft and the automated systems flying them. Advanced artificial intelligence is needed to fly large numbers of autonomous aircraft without _25_ them into one another or, say, the local news channels traffic helicopter. Carrying people from poin

14、ts A to B seems simple enough, but even the best AI struggles with _26_ “What, for example, would a drone do if a landing area suddenly became unavailable?” asks Sanjiv Singh, a Carnegie Mellon University robotics researcher. Instead of _27_ to fully automated passenger drones, he suggests first tes

15、ting the necessary AI in unmanned cargo runs, and adopting a “mixed mode” approach in early passenger services where pilots are assisted by AI co-pilots. Technical challenges aside, start-ups (创业公司) promoting the technology will have to find a way to convince the public to give their drones a try, s

16、omething that requires a much bigger leap of faith than getting into the _28_of a self-driving car. Passenger drone makers are “obviously still in the very early stages of technology development and improving the _29_ ,” says Mike Hirschberg, executive director of the American Helicopter Society Int

17、ernational. “But 20 or 30 years from now life may be a little like The Jetsons where you take advantage of the third dimension and have much more _30_ especially in urban close quarters where ground transportation is jammed.”The passenger drone progress may follow a sloping takeoff rather than verti

18、cal (垂直的) leap. Carnegie Mellons Singh sees a long road ahead filled with lots of testing, analysis, regulation and efforts to win the publics trust before the technology becomes a viable transportation option. “There is the danger of someone moving too fast and then having a problem that sets the i
