Darpa pulls plug on boeing experimental electric plane — the motley fool electricity transmission costs

##

On Thursday, Aurora issued a press release advising that "it has reached an agreement with the Defense Advanced Research Projects Agency (DARPA) to transition its X-Plane program technology to commercial applications." Aurora characterized this agreement as "expanding on DARPA’s vision" and a move to take advantage of "completely new markets." The folks at Aviation Week, however, had a different take on the news.

To hear AW tell it, what really happened last week is that DARPA "canceled" plans to advance LightningStrike to "Phase 3" and conduct full-scale flight tests, which had suffered setbacks related to the plane’s electrical generator, and had fallen behind schedule. DARPA also noted that it was having trouble finding a "service partner" (i.e. a military service) to develop LightningStrike into an official Pentagon program. AW described this decision as "a blow" to Aurora and its new owner Boeing — and it sure sounds like it could be. LightningStrike grounded?

Is this the end for LightningStrike? Not necessarily. In a statement to AW, DARPA noted that there is "strong interest in a civil or commercial transition" for LightningStrike. The plane’s ability to launch and land from an airstrip no bigger than a parking space, for example, then fly from place to place under remote control, would make the aircraft ideal for service as a "drone" air taxi. And in fact, Uber has already expressed interest in using LightningStrike for this purpose. Even prior to DARPA’s decision to exit the project, Aurora had been in talks with Uber to build a fleet of 50 VTOL aircraft for Uber to test "drive."

Boeing’s new subsidiary also has a deal with NASA "to perform a comprehensive evaluation of the Single-aisle Turboelectric Aircraft with Aft Boundary Layer propulsion (STARC-ABL) aircraft concept." Like LightningStrike, STARC-ABL would utilize turboelectric propulsion. Unlike LightningStrike, STARC-ABL would use electric motors to supplement, not replace, an airliner’s usual gas turbine airplane engines.

Last summer, before Boeing announced its purchase of Aurora, the soon-to-be-subsidiary was named as one of two recipients of a contract with the U.S. Air Force to support the latter’s " Aerospace Systems Air Platform Technology Research" project. This contract, which would run through 2025 and be worth up to $499 million for the companies participating ( Northrop Grumman also has a piece of the contract), pays Aurora to conduct research into "autonomy, electric propulsion, advanced manufacturing, multi-vehicle coordination, and advanced multidimensional optimization" for use in military drones.

The ASAPTR contract is potentially a very lucrative deal for Boeing. I say this not just because of the up-front money (which is substantial, and could even be more than Boeing paid to acquire Aurora, since that sum, while still not disclosed , was apparently not large enough to be considered "material" to Boeing), but because of the potential for Boeing to win follow-on manufacturing contracts if Aurora’s research goes well.

And yet, those words from DARPA do raise concerns: No service partner interested in Aurora’s tech… That could mean that, eight months after awarding Aurora the ASAPTR contract, the Air Force — definitely a military service — is no longer interested in what Aurora has to offer.
