NEC eVTOL Testbed

NEC Corporation has developed an electric Vertical Take-Off and Landing (eVTOL) testbed aircraft to help development autonomous management systems for eVTOL aircraft. NEC stated that the much larger eVTOL aircraft fly differently than small drones and they need a full-size eVTOL aircraft to obtain the data needed to allow them to make and validate working aircraft management systems.

NEC reported that they’ve been flying their eVTOL testbed behind closed doors for several months in Abiko, near Tokyo, but it was first revealed to the public on August 5, 2019 (image from video by Yuri Kageyama). The tethered test flight took about one minute with an altitude of about three meters (about 10 feet) and was flown inside a giant cage to protect everyone viewing the flight.

Upon inspection of the photos and videos of their aircraft, it appears that the four (4) propellers, protected by enclosing ducts, do not tilt on any axis for flight control. Therefore, flight control is most likely achieved by each individual propeller adjusting its speed independently to make any directional changes.

Behind the somewhat underwhelming, drama-free demonstration lies a bigger ambition: Japan’s government wants the country to become a leader in flying cars after missing out on advancements in technology such as electric cars and ride-hailing services. The country’s technological road map calls for shipping goods by flying cars by around 2023 and letting people ride in flying cars in cities by the 2030s.
