Kaman Aerospace Corp. has received a contract from the U.S. Marine Corps on behalf of Team K-MAX to demonstrate the ability of the unmanned K-MAX helicopter to deliver cargo to troops in extreme environments and at high altitudes. Kaman will award a subcontract to fellow Team K-MAX member Lockheed Martin to integrate a beyond-line-of-sight data link and UAS mission-management system with its proven aerial truck. Team K-MAX will demonstrate the unmanned helicopter’s capability to deliver cargo to a round-trip distance of 150 nmi. The Marine Corps objective is to move 20,000 lb of cargo in a 24-h period. The 5100-lb K-MAX helicopter is capable of lifting 6000 lb at sea level, due to the aircraft’s counter-rotating intermeshing rotor design that eliminates the need for a tail rotor. The demonstration is scheduled for late 2009.
