UAS Demonstrated Autonomous And Remote Control

Lockheed Martin Corporation and Kaman Aerospace Corporation have successfully demonstrated to the U.S. Marine Corps the capability of the Unmanned K-MAX helicopter to resupply troops by unmanned helicopter at forward operating bases in Afghanistan. During a series of flights last week in subfreezing temperatures at the U.S. Army's Dugway Proving Ground, UT, the Unmanned K-MAX demonstrated autonomous and remote control flight over both line-of-sight and satellite-based beyond line-of-sight data link.

"We met or exceeded the requirements within the scheduled three-day timeframe of the demonstration," said Dan Spoor, Aviation Systems vice president at Lockheed Martin's Mission Systems & Sensors facility in Owego, NY. "The system performed a rigorous set of cargo resupply scenarios as programmed, allowing the ground-based operator to monitor progress, and make adjustments to aircraft positioning only when requested by the Marine Corps for demonstration purposes."

Performance attributes demonstrated included hovering at 12,000 ft. with a 1,500-pound sling load; delivering 3,000 pounds of cargo well within the six-hour required timeframe to a forward operating base (two 150 nm round-trip flights); remotely controlling flight and a precision load delivery by a ground-based operator in both day and night conditions; and uploading a new mission plan to the aircraft's mission management system during flight.

As an optional demonstration, Team K-MAX showcased the Unmanned K-MAX helicopter's four-hook carousel, which enables multi-load deliveries in a single flight. Lifting a total cargo of 3,450 pounds, the aircraft flew to three pre-programmed delivery coordinates, autonomously releasing a sling load at each location. At the customer's request, the fourth load delivery was performed under manual control by the ground operator.

"The Unmanned System (above, right) performed operationally representative cargo resupply scenarios, and each time the system delivered as promised," said Sal Bordonaro, President, Kaman Helicopters, a division of Kaman Aerospace Corporation. "This capability gives the Marine Corps a proven unmanned power lifter to bring vital cargo to troops on the battlefield without the need for ground vehicles and manned helicopters."

Team K-MAX has flown the Unmanned K-MAX nearly 400 hours in unmanned mode since 2007. The demonstration fulfilled an $860,000 U.S. Marine Corps contract awarded to K-MAX manufacturer Kaman Aerospace in August 2009. A manned version of K-MAX (above) has accumulated more than 250,000 flight hours, conducting repetitive lift operations for the construction and logging industries worldwide.
