Founded in July 2018, SkyDrive is an electric vertical takeoff and landing (eVTOL) company based in Toyota City, Japan. Tomohiro Fukuzawa is the chief executive officer and Nobuo Kishi is the chief technology officer. (All photos and graphics, SkyDrive credit.)
A brief history of the company reveals that in September 2012, Tomohiro Fukuzawa formed a volunteer group automotive, drone and aviation industry professionals, who would meet outside of business hours and started discussions by first stating "Let's do something interesting". Based on Fukuzawa automotive background, he asked the group a fundamental question, "Why do people move?" Eventually, more than 100 ideas were talked about, such as cars which could also be submarines, to small enough cars that could move from room to room, inside a building.
After a year and a half of discussions, in 2013, the group decided on flying cars. The company they formed was called Cartivator. The company name was created by combining the word car and cultivate with the definition of cultivate being more towards the word pioneer. As the business matured, it became difficult to continue with volunteer workers. This why that in July 2018, about 30 people from Cartivator founded the SkyDrive Corporation.
The company's goals for developing eVTOL advanced air mobility (AAM) aircraft is to make safer aircraft, less costly aircraft, less noisy aircraft, autonomous aircraft and aircraft that require less infrastructure. The plan is to start using the aircraft in the mid-2020s for air transportation of goods and people in areas where conventional public transportation is slow or almost nonexistent in rural and urban areas.
In 2014, a one-fifth scale SD-01 was flown by Cartivator (now SkyDrive) and had eight propellers, eight electric motors and fixed skid type landing gear. The one-fifth scale prototype had variable pitch propellers for better control of the prototype.
On June 3, 2017, a full scale SD-01 eVTOL prototype made its first outdoor flight. The aircraft was planned from the beginning to be an uncrewed prototype, with eight propellers and eight electric motors with a target cruise speed was 50 km/h (31 mph). The flying prototype picture show the prototype with a metal skeleton frame with no finished outer skin, with possibly skid type landing gear.
Another modified SD-01 was showcased at the Automotive Engineering Exposition 2018 Yokohama (Japan) May 23–25, 2018. From the pictures available, this SD-01 model is both a VTOL aircraft and road vehicle, with three wheels. To keep weight and complexity to a minimum, the rear wheel has an in-wheel electric motor and the front wheels use the same electric motor system as Toyota's electric single seat car called the COMS.
The company has stated they plan to make their eVTOL aircraft with three wheels so the aircraft can truly be a flying car. The target cruising ground speed is 60 km/h. The company name SkyDrive most likely means that its vehicles can fly in the "Sky" and can also "Drive" on the road, hence the name SkyDrive.
- Aircraft: Several uncrewed eVTOL prototypes
- Capacity: 0 passengers
- Cruise speed (target): 50 km/h (31 mph)
- Maximum speed: 100 km/h (62 mph)
- Maximum altitude: 10 m (33 feet)
- Maximum takeoff weight: 400 kg (882 lbs)
- Propellers: 8 propellers
- Electric motors: 8 electric motors
- Power source: Battery packs
- Dimensions: 3.7 m L (12 feet) x 3.7 m W (12 feet) x 1.5 m H (4.9 feet)
- Safety Features: Distributed Electric Propulsion (DEP), provides safety through redundancy for its passengers and/or cargo. DEP means having multiple propellers and motors on the aircraft so if one or more motors or propellers fail, the other working motors and propellers can safely land the aircraft.
