Reason for the name-change: Darpa lost interest in the idea of jeep that could fly; instead it preferred to focus on an autonomous flyer that could carry a Jeep, or a medevac capsule, or a box of stuff -- anything that can fit between the vehicle's splayed legs. After strapping on the load, the ducted, two-propeller, autonomous craft would hold its props in the horizontal plane for liftoff, then rotate them to or nearly to the horizontal plane for forward flight.
The tricky part is in melding all elements of the craft into a single, seamless system of flight control, which involves manipulating the variable-pitch rotors and pointing the exhaust stream in the appropriate direction.
The contractors are Piasecki Aircraft, known for its helicopter expertise, and Lockheed Martin. The first test flight is due sometime next year. Possible customers include the U.S. Army, Marine Corps. and Special Forces.
