Aurora Flight Sciences was started in May 1989 by John Langord, III (PhD in Aeronautics and Public Policy from MIT) with two employees and then fast forward to 2018, has about 550 employees among its four main sites. Aurora bills itself as “an innovative technology company which strives to create smarter aircraft through the development of versatile and intuitive autonomous systems.” On Nov. 8, 2017, The Boeing Company acquired Aurora Flight Sciences.

The Aurora Passenger Air Vehicle (PAV) is an all-electric Vertical Take-Off and Landing (eVTOL) aircraft with eight propellers for vertical flight, a tail mounted pusher-prop for forward flight and a three-surface wing configuration for cruising. The aircraft is 30 ft (9.14 m) long, 28 ft (8.53 m) wide, a maximum range of 50 miles (80 km), carry a load of 496 lbs (225 kg) and its maximum speed is 112 mph (180 km/h). It is a two (2) passenger aircraft and can be piloted or flown autonomously.

Aurora is an independent subsidiary of Boeing. What that means is that it combines Aurora’s innovation with Boeing’s’ strength. They are the world’s largest [aerospace company] with one of the most successful product lines. But they do not build eVTOL today. No company builds eVTOL today. That is a market that does not exist.

So how do you go after a market that doesn’t exist? The idea is to have Aurora explore these markets that involve very advanced technology, then do the prototyping work, then the market exploration work, and hopefully find new markets and new programs that can be fed into Boeing so that when someone wants a few thousands of those airplanes, Boeing can do it. So that’s the idea behind the merger, our innovation with their size and strength. — John S. Lanford, III.

Aurora’s aircraft is born out of a 2017 partnership with Uber as part of the Uber Elevate Mission. Initially, a 1/10 model was flown with and without a fuselage. This was followed by a fully configured 1/4 sized model. On Jan. 22, 2019, a full-size prototype of this design (registration details for tail number N83AU here) was successfully flown at the Manassas Regional Airport in Manassas, Virginia, USA. The PAV prototype completed a controlled takeoff, hover and landing testing the vehicle’s autonomous functions as well as the ground control systems.

Aurora expects that the noise at takeoff will blend in with background road traffic noise at a height of 6-100 ft (18-30 m), making the aircraft essentially “inaudible” from the ground when in cruise flight.

This is what revolution looks like, and it’s because of autonomy, said John Langford, III, president and chief executive officer of Aurora Flight Sciences. Certifiable autonomy is going to make quiet, clean and safe urban air mobility possible.

As one of Uber Elevate’s vehicle partners, the aircraft has been designed as an Air Taxi to operate in urban environments and to easily fly, to and from Uber’s Skyports. The PAV for Uber’s missions will be a four (4) passenger eVTOL aircraft. Aurora also has other hybrid-electric VTOL technologies it can apply to the Urban Air Mobility (UAM) market.

On May 8, 2018, at the second Uber Elevate Summit, Aurora unveiled three design variants that are also being considered.

Here is a January 2019 graphic believed to be the current configuration for the Uber Elevate mission.
