Joby “cranks up the volume” as vital EGM beckons, new video release

By Chris Stonor

Joby Aviation is doing everything possible to make sure its Extraordinary General Meeting (EGM) of shareholders on August 5th runs smoothly. The meeting’s aim is to pass a vote on the approval and adoption of the company’s merger with Reinvent Technology Partners (RTP), leading to a Stock Market floatation later this year.

No surprise then that Joby is pulling out all the stops. Apart from securing an impressive array of Directors to its Board in recent months, there has been a number of videos released including this latest and most spectacular one to date showing the company’s aircraft completing what is probably “the longest eVTOL flight to date, exceeding 150 miles in a single flight, including a vertical take-off and landing. The 1 hr 17 min flight was achieved with a full-size prototype earlier this month during developmental flight testing,” reports a company press release.

Yes, that is impressive.

The release continues, “The flight was completed at Joby’s Electric Flight Base in Big Sur, CA earlier this month as part of the company’s ongoing flight test campaign. The aircraft, piloted from the ground by Joby’s Chief Test Pilot, Justin Paines, took off vertically before transitioning to forward flight and completing 11 laps of a predefined circuit.”

And goes on, “After more than 1 hour and 17 minutes in the air, the aircraft landed vertically, having covered a total distance of 154.6 statute miles.”

JoeBen Bevirt, founder and CEO of Joby, commented, “We’ve achieved something that many thought impossible with today’s battery technology. By doing so we’ve taken the first step towards making convenient, emissions-free air travel between places like San Francisco and Lake Tahoe, Houston and Austin, or Los Angeles and San Diego an everyday reality.”

Joby’s prototype aircraft uses commercially available lithium ion batteries that have been adapted for aerospace use. An 811 NMC cathode and a graphite anode cell were selected, following internal testing, to deliver the optimal trade-off between the specific energy required to fly the aircraft 150 miles, the specific power to take-off and land vertically and the cycle life to deliver an affordable service. Trials show that this battery is capable of more than 10,000 expected short flight cycles.

The team developing Joby’s energy system is led by Jon Wagner, Head of Powertrain and Electronics, who previously led battery engineering at Tesla.

He explained, “Since the day I joined Joby four years ago, we’ve worked hard to maximize the energy efficiency of this aircraft and prove what we have always known to be possible with today’s battery technology. With the right cell chemistry and a lot of hard work across the entire engineering team, we’ve been able to create a remarkably efficient aircraft that can make the most of today’s commercially available batteries.”

Justin Paines, a former Royal Air Force test pilot who helped develop the controls for the F-35 Joint Strike Fighter before joining Joby as its Chief Test Pilot, added, “We’ve been building up to this for several months now, flying progressively longer sorties. As we’ve extended the range, we’ve been able to identify modifications to the aircraft that improve efficiency and, for the final few tests, we were able to upgrade the landing gear on our prototype aircraft to one with a drag profile more representative of what we expect to see on our production aircraft.”

He continued, “While we still have plenty more testing to do, achieving this milestone is an important validation of our technology and I’m incredibly proud to have played a small part in what is, to our knowledge, the longest all-electric eVTOL flight performed to date.”

Footnote 

Joby’s aircraft is expected to start commercial passenger service in 2024, transporting a pilot and four passengers at speeds of up to 200 mph.

The company is working towards certifying its aircraft with the Federal Aviation Administration, having already agreed on a “G-1” certification basis and been awarded a US Air Force Airworthiness Approval.
