The Defense Advanced Research Projects Agency (DARPA) recently launched a challenge with the goal of increasing unmanned aircraft systems (UAS) payload weights.
Currently, the payload-to-weight ratio is 1:1 or less. The DARPA Lift Challenge aims to increase the payload-to-weight ratio to 4:1. The ratio is plausible because of recent advances in aerodynamic design, materials science and propulsion systems, according to DARPA experts.
The agency seeks drone designs that can carry payloads more than four times their weight and can be used for a new range of possible military and civilian applications.
Competitors must design an aircraft that weighs no more than 55 pounds and can lift a minimum payload of 110 pounds across a five-nautical mile circuit course. All participating individuals and teams must adhere to Federal Aviation Administration regulations.
The agency is offering $6.5 million in prize money.
“DARPA recognizes the best solutions often come from unexpected places,” Phillip Smith, DARPA Lift Challenge program manager, said. “We’ve deliberately created an open design Challenge format to encourage out of the box thinking.”
Registration will run January though May, and live performance trials will be held in the summer. The agency is accepting feedback on the draft rules through Nov. 26.
