The U.S. Defense Advanced Research Projects Agency (DARPA, Arlington, Va., USA) announced on Oct. 12 the six vendors selected to participate in the 12-month effort to develop the Transformer (TX) flying HMMWV.
The six vendors include: AAI Corp. and Lockheed Martin
Company, prime system integrators; Carnegie Mellon University and Pratt & Whitney Rocketdyne, developers of critical enabling technology; and Aurora Flight Sciences partnered with ThinGap, and Metis Design Corp, Small Business Innovation Research (SBIR) recipients.
The TX program aims to develop a robust ground vehicle that can transform into an air vehicle with vertical take-off and landing (VTOL) capability, while offering significant operational flexibility with the ability to efficiently travel 250 nautical miles on land and in the air, or any combination, while carrying up to 1,000 lb/454 kg. This payload requirement represents up to four Warfighters and their equipment, including a critical medical evacuation capability. It is envisioned that guidance and flight control systems will allow for semiautonomous flight, permitting a nonpilot to perform VTOLs, transition into forward flight, and update the flight path in response to changing mission requirements or threats.
With this type technology, transportation will no longer be restricted to trafficable terrain that tends to make movement predictable. Benefits of enhanced mobility are numerous. The capabilities TX plans to provide may allow for improved resupply operations, fire-team insertion and extraction and reduced time for medical evacuation. Key to the success of this technology is the ability for guidance, navigation and control of the TX to be conducted without a dedicated pilot.
During the program’s first phase, performers will conduct trade studies to develop and mature propulsion systems, adaptable wing structures, advanced lightweight materials, the advanced flight control system, the air/ground configuration designs, and energy distribution systems. The developers of critical enabling technologies will work with the prime system integrators, incorporating their technology for a possible second phase. These trade studies will allow for development of a detailed technology maturation plan to ensure a feasible design of the vehicle and its supporting technology. Results of this initial phase will be used by DARPA to inform future phases.
