Multi-UAV/Apache Cooperative Flights Planned By Boeing This Summer

After demonstrating level-4 control of an unmanned aerial vehicle (UAV) and its weapons from the cockpit of an AH-64D Apache Longbow helicopter earlier this year, Boeing hopes to conduct cooperative flights with the Longbow and multiple UAVs this summer at Yuma Proving Ground, Ariz.
Boeing hopes to use its Unmanned Little Bird and ScanEagle UAVs in the demonstration, which would be sponsored by the U.S. Army's Aviation Applied Technology Directorate (AATD).
"We'd like to have the ScanEagle out there, loitering, finding us a target, and then start talking to the Little Bird, who will then relay [images] to the manned platform of what they see," Waldo Carmona, Boeing's director of Advanced Army Systems, told The DAILY.
At that point, the Apache pilot can "decide if you want to engage it and then work together with ScanEagle and the Little Bird to engage that target," Carmona said. Both UAVs would be tasked and controlled from the Apache's cockpit.
In February at Boeing's facility in Mesa, Ariz., the company demonstrated the ability of the Apache to control the Unmanned Little Bird's weapon payload as part of the Airborne Manned/Unmanned System Technology Demonstration (AMUST-D) program. The tests reached Level-4 control, which means every function of the UAV other than takeoff and landing was managed by the Apache.
The Longbow remained on the ground while it controlled multiple payloads on the airborne Little Bird, communicating via the tactical common data link (TCDL). "We were able to do laser designation from the Little Bird, we were able to shoot from the Little Bird ... all being controlled from the Longbow," Carmona said. The tests used the "House Mouse" Hellfire, an instrumented, inert version of the missile. Live fire tests would be the next step.
Apache pilots were able to control the UAV's weapons through a new page on their displays, according to Carmona. The page contained information on the UAV's remaining ammunition, fuel, and available sensors, allowing the UAV to be used as "a detached weapons store," he said.
Unmanned Little Bird plans
The Unmanned Little Bird prototype is a modified MD 530F helicopter that can be flown with or without a pilot onboard. Last year the UAV completed a series of AATD-sponsored weapons tests at Yuma (DAILY, Oct. 4, 2005).
The UAV is expected to begin shipboard testing with the Navy within the next two months, Carmona said. First flights will be manned, after which the team will analyze flight data and then return to sea again for autonomous flights.
