The Defense Advanced Research Projects Agency has awarded four contracts for the first phase of a plane that can take off and land like a helicopter but actually fly like a real plane.
The agency is looking for “innovative cross-pollination between the fixed-wing and rotary-wing worlds” in developing the VTOL Experimental Plane (VTOL X-Plane), according to an announcement. DARPA has awarded prime contracts to Aurora Flight Sciences, Boeing, Karem Aircraft and Sikorsky Aircraft.
Vertical takeoff and landing, or VTOL, aircraft have always had to sacrifice range or efficiency in order to increase speed, DARPA said. The VTOL X-Plane project is looking is looking for “radical” improvements in both vertical and cruise flight capabilities.
“We were looking for different approaches to solve this extremely challenging problem, and we got them,” said Ashish Bagai, DARPA program manager. “The proposals we’ve chosen aim to create new technologies and incorporate existing ones that VTOL designs so far have not succeeded in developing. We’re eager to see if the performers can integrate their ideas into designs that could potentially achieve the performance goals we’ve set.”
The program is looking for a prototype that could:
The four companies submitted plans for unmanned aircraft, but DARPA said the VTOL X-Plane program plans to develop technologies that would be useful to both manned and unmanned aircraft.
