Humans Take a Step Closer to ‘Flying Cars’


In the 1880s, the primary car was developed and about twenty years later, the Wright brothers in North Carolina invented the primary profitable airplane. Today, the world is nearer to combining these two ideas as a Japanese tech firm stated it accomplished a manned check flight of a “flying car.”

The firm, SkyDrive, stated in a information launch on Friday that it had accomplished a flight check utilizing “the world’s first manned testing machine,” its SD-03 mannequin, vertical takeoff and touchdown (eVTOL) car. The flight time was 4 minutes, the corporate stated.

The plane has one seat and operates with eight motors and two propellers on every nook. It lifted about three meters (or about 10 ft) into the air and was operated by a pilot, the corporate stated.

Tomohiro Fukuzawa, SkyDrive’s chief government, stated on Saturday that 5 years in the past there have been numerous prototypes of flying vehicles, often with mounted wings. SkyDrive’s product, he stated, was probably the most compact in measurement and was lighter in contrast with different designs.

Safety is one of two challenges preventing the technology from becoming widely used, said Derya Aksaray, an assistant professor of aerospace engineering and mechanics at the University of Minnesota. Safe autonomous technology for eVTOL aircrafts is still being developed, Professor Aksaray said.

“These vehicles need to look at their environment, assess the situation and act accordingly,” she said. “They cannot wait for a pilot or an operator to say, ‘Now do this, now do that.’ We cannot wait for that kind of micromanagement of the vehicle.”

The other challenge is design: The vehicles should be powerful enough to carry any necessary weight, yet quiet enough to fly at undetermined low altitudes, she said.

Ella Atkins, a professor of aerospace engineering at the University of Michigan, expressed mixed views on the practicality of eVTOL machines.

“They are going to be more energy efficient than helicopters that use a lot of fuel but they will be less energy efficient than cars because they have to lift themselves,” she said. “From a cost perspective, they won’t be practical to go to the grocery store.”

Professor Atkins said these machines may be better suited for satellite communities of cities or countries with difficult terrain.

“These vehicles can provide transportation,” Professor Atkins said, adding that “these communities might skip right over having roads” and use the aircraft as their main form of transportation.

Mr. Fukuzawa said SkyDrive plans to begin selling a two-seat version of its eVTOL by 2023 for about $300,000 to $500,000. He projected the price will decrease by 2030.

“With any new technology, it will be very expensive in the beginning,” Professor Aksaray said.

Professor Atkins echoed that observation and said it’s unlikely that private citizens with a modest income would be able to afford one in the next 20 years.

“We’re at the entrant phase,” she said. “We don’t have the mass production we would need to buy down the costs of all the development, research, deployment and manufacturing at a small scale.”

Professor Aksaray said humans are on the verge of a new mobility revolution, reminiscent of the ones created by the invention of the automobile and the plane.

“If this becomes successful,” she said, “I think that would definitely create a different means of transportation. We are going to benefit a lot by reducing congestion and overcoming the geographical constraints of ground mobility.”
