The Air Force is crowdsourcing its aircraft engine research.

The Air Force Research Laboratory is offering a $2 million prize to the first research team that can develop a newer, smaller, more fuel-efficient engine.

The contest will kick off in May, with the goal to design craft a new engine design with twice the fuel efficiency and three times the power-to-weight of an aviation piston engine, according to the Dayton Daily News in Ohio.

The contest is hosted by AFRL, based at Wright-Patterson Air Force Base, Ohio.

The Air Force service says that new materials, design tools and manufacturing technology can help teams create the new engine design, according to the Daily News.

AFRL is hosting industry days on March 24 and 25 at the Wright Brothers Institute in Dayton and a location on the West Coast that has not yet been determined. Teams must register by March 16.
