DARPA’s winning lift drone carried 3.84 times its own weight

AVIDrone won DARPA’s Lift Challenge with an aircraft that carried 3.84 times its own weight in a scored run. The result, announced August 11 after the competition ended August 9, approached but did not reach DARPA’s four-to-one target.

The Maryland company received $1.25 million. Under the rules, teams below the target earned half the prize assigned to their finishing position. MTech Operations followed at 3.64 to one, and Xtreme Aerial Concepts at 3.45 to one.

A separate technology award went to DefendTex. DARPA reported a 9.63-to-one ratio for its design, but the aircraft did not complete a scored run. That result cannot replace AVIDrone’s score at the top of the official performance ranking.

The competition’s task was more demanding than briefly lifting a heavy object. The announced requirements limited aircraft weight, including the energy source, to 55 pounds and called for carrying at least 110 pounds over a five-nautical-mile circuit.

DARPA had described conventional multirotor payloads as generally around the aircraft’s own weight or less. Seeking a much higher ratio encouraged teams to reconsider airframes, rotors and propulsion rather than simply enlarge an existing design.

The direct-to-Phase-II small-business topic required prior proof of concept; it was not an automatic award to contest winners. DARPA’s page listed the opportunity as closed September 23.

Can the next three copies perform alike?

DARPA’s related commercialization topic moved the question from a competition aircraft to repeatable hardware. It set out separate tracks for aerodynamic structures and powertrain subsystems, with manufacturing, documentation and certification work alongside performance tests.

One early structural test called for three identical components made with scalable processes. Their failure loads were to vary by less than 10 percent. The powertrain track likewise required three units, with less than 5 percent variation in specified performance measures.

Those requirements make consistency an explicit part of the engineering task. A promising prototype is more useful to another manufacturer when its parts can be reproduced and its performance is predictable.
