Ohio-based electric vehicle manufacturer Workhorse Group plans to unveil its SureFly hybrid gas-electric helicopter concept at the Paris Air Show on June 19. The two-passenger SureFly is designed to compete in the newly created eVTOL market with a maximum payload of 400 pounds, a range of 70 miles and a cruising speed of 70 mph. The aircraft is powered by a BMW 600cc two-cylinder generator engine linked to a parallel bank of battery packs offering redundant power and eliminating the need for long battery recharging between flights. The electrical system powers electric motors linked to four propeller arms, each with two contra-rotating propellers. The batteries can power the motors in the event of generator failure. The airframe also has a ballistic parachute. Workhorse plans to begin test flights this year and intends to achieve FAA certification in late 2019. Workhorse has developed a variety of hybrid electric vehicles, including step vans and pickup trucks. In February, UPS successfully tested Workhorse's HorseFly UAV for home package delivery service from atop a package-delivery car.
