First flight of the Workhorse SureFly “electric helicopter” was made on Monday, April 30, 2018 at the Cincinnati Municipal Lunken Airport in Cincinnati, Ohio. The flight was a 10-second untethered hover. This was the world’s first manned flight of a hybrid-electric VTOL aircraft. Initially, the concept was planned to fly at CES2018, after tether testing in Jan. 2018.
The company further announced that on June 1, 2018, the US Federal Aviation Administration had accepted the company’s application for type certification. The company notes “the SureFly design appears to be the first hybrid-electric eVTOL multi-copter to reach this important milestone with the FAA.”
The company posted a video of flight testing on Aug. 6, 2018 of the SureFly conducting higher hovers from testing on Aug. 2, 2018.
According to the Workhorse website: “SureFly is a personal helicopter/eVTOL aircraft designed for safe and easy flight. With eight independent motors each driving a single carbon fiber propeller, a backup battery power system, and a ballistic parachute to safely land in the event of emergency, the SureFly provides unparalleled safety for a personal aircraft.”
The company announced the program in a press release on May 31, 2017, stating: “It features a gas combustion engine generating electricity and a parallel battery pack offering a redundant backup power source, eliminates the need for long battery charging periods between flights. SureFly is designed to be easy to operate, and is expected to be capable of carrying two passengers up to 70 miles.” The SureFly is expected to sell for less than $200,000 each.
An accident occurred on April 11, 2018, when the SureFly rolled onto its side during a demonstration, luckily not injuring the test pilot.
