Electric Helicopter Makes Historic Flight

Electric vertical takeoff and landing (eVTOL) aircraft have been all the rage for a few years, but what about good old helicopters? Naturally, conventional helicopters are powered by fossil fuels, but they can be electric too. One converted electric helicopter is eager to go on an epic journey to show the potential there, and for now it has demonstrated that potential on a small scale on a record flight.

The helicopter was a third-generation e-R44 fully electric conversion of the popular Robinson R44 helicopter. It was reportedly the first electric helicopter to go from one city to another or from one airport to another. This electric helicopter flew along the Coachella Valley of California from Jacqueline Cochran Airport (KTRM) to Palm Springs International Airport (KPSP). That’s 24 miles (39 kilometers), which took 20 minutes to cover.

The pilots on this historic flight were Ric Webb, CEO of OC Helicopters, and Dr. Martine Rothblatt, CEO of United Therapeutics. They also loaded the helicopter with 50 pounds (23 kilograms) of faux storage in order to “simulate a transplant organ care system in the rear cabin,” as Vertical writes.

Tier 1 Engineering and Lung Biotechnology PBC enabled and sponsored this flight. Tier 1 Engineering has been working on electric helicopters and setting records in this segment for years. Tier 1 Engineering President Glen Dromgoole says that the e-R44 electric helicopter had 50% of battery state of charge when it completed its airport-to-airport flight. “We believe we’re developing a really practical solution for short duration rotorcraft flights such as organ deliveries, pilot training, scenic tours and other inner-city trips,” Dromgoole added.

“An accomplished fixed-wing and helicopter pilot, Rothblatt started researching the feasibility of electric vertical flight about six years ago and shared the specifications of zero-emissions electric rotorcraft with a number of aerospace companies to launch a research project,” Vertical notes, adding that Rothblatt started researching the potential for electric helicopters about 6 years ago, which would be around the time that the Tesla Model 3 was revealed. “Dromgoole was the first person to positively respond to Rothblatt’s line of inquiry. Tier 1 Engineering received a contract in early 2016 to rapidly build and fly a proof-of-concept electric helicopter.”

You can visit Vertical for more details on how the electric helicopter was made, what parts it includes, and previous milestones, such as its September 2016 five-minute flight using up 20% of the electricity in its battery. Back in January 2019, we reported on this same electric helicopter setting a Guinness World Record for the farthest flight in an electric helicopter — 34.5 miles (30 nautical miles).

What’s clear if you look through the past several years of this one converted electric helicopter’s story, let alone the industry as a whole’s story, is that the technology has improved a lot in the past several years and electric flight is getting closer and closer to commercial competitiveness.
