On Dec. 2, Vanilla Aircraft‘s VA001 unmanned aircraft system (UAS) completed a world record non-stop, unrefueled 56-hour flight.

The flight was supported by the technology innovation investments of the U.S. Department of Defense’s Rapid Reaction Technology Office (RRTO) and DARPA-funded efforts through Naval Air System Command (NAVAIR 4.11 – Patuxent River).

The flight, planned as a 120-hour mission, was ended early because of forecasts of severe icing and range restrictions. However, the airplane landed with enough JP-8 fuel on board for an additional 90 hours of flying, or enough for a total of six days of flight.

The flight was certified as a world-duration record for combustion-powered unmanned aerial vehicles (UAVs) in the 50-500 kilogram subclass (Fédération Aéronautique Internationale Class U-1.c Group 1). A representative from the National Aeronautic Association was present to witness the record. Moreover, the flight was the fourth-longest for any unmanned airplane and the 11th-longest for an airplane of any type (manned or unmanned, solar or fuel-powered).

Originating and ending at Las Cruces International Airport, the flight was conducted under the authority of the New Mexico State University UAS test site designated by the Federal Aviation Administration (FAA).

“This effort represents tremendous and unprecedented coordination among civil, defense, academic, and private industry to bring a heretofore only imagined capability to reality,” said Vanilla Aircraft CEO Rear Adm. Timothy Heely (ret.).

Small unmanned aerial vehicles (UAVs) are an increasingly important means for military forces — especially small dismounted units — to bring extra communications or intelligence, surveillance and reconnaissance (ISR) capabilities to the field. Current designs, however, offer relatively limited range and flight endurance; additionally, their need for frequent refueling, specialized launch and recovery equipment, and regular maintenance often limit them to flying from fixed bases close to the front lines.

“This record-breaking flight demonstrated the feasibility of designing a low-cost UAV able to take off from one side of a continent, fly to the other, perform its duties for a week, and come back — all on the same tank of fuel,” said Jean-Charles Ledé, DARPA program manager. “This capability would help extend the footprint of small units by providing scalable, persistent UAV-based communications and ISR coverage without forward basing, thereby reducing personnel and operating costs. We’re very pleased with what the Vanilla team has accomplished.”

The airplane carried 20 pounds of actual and simulated payload, flying at 6,500 to 7,500 feet above mean sea level (MSL), and was a further step for the VA001 towards demonstrating the system’s objective performance of carrying a 30-pound payload for 10 days at an altitude of 15,000 feet.

The payload included a NAVAIR-provided relay and operated continuously throughout the flight to demonstrate functionality out to the maximum range.

The airplane also carried a NASA-provided multispectral imaging payload as a demonstration of Earth science and agricultural remote sensing.

“The VA001 has transformational potential, providing a scalable aerial system solution without increasing personnel or operating costs,” said co-founder and chief engineer Neil Boertlein. “The ability of a low-cost platform to provide persistent surveillance, battlefield pattern of life, or aerial mesh network relay, in a responsive and robust manner, and without forward basing, does not currently exist.”

Vanilla Aircraft is also planning a groundbreaking role for the VA001 in commercial applications, especially in agriculture. Vanilla is exploring strategic partnerships and equity financing to expand into this market.

“The VA001 would be a cost-effective option for widespread and regular low-level surveying,” said co-founder and program manager Jeremy Novara. “We could fill a wide cost and payload-capability market gap between small electric and large military unmanned aircraft, which is perfect for many commercial applications.”

    The Boeing Condor UAV recorded a flight of 58 hrs 11 minutes in 1989, with demonstrated capability of significantly longer endurance. Probably not observed by an official NAA observer, and therefore not formally recognized, but certainly impressive for the time — 27 years ago!. Power was two internal combustion turbocharged Contental engines. Wingspan 200 ft, weight 20,000 lbs, ceiling 67,000 ft, payload unspecified, but probably several hundred pounds. Flights were autonomous, including takeoff and landing, with in-flight updates. The Condor is currently on display in the Hiller Aviation Museum at the San Carlos, California airport.
