In March 2011, MD Helicopters, Inc. in Mesa, AZ won a competition for the Afghan Air Force that could reach as many as 54 helicopters over the life of the 4 year contract, giving it an implicit value of up to $180 million. Discussions with MD Helicopters confirmed that these are MD 530Fs, designed for high altitude and/or hot weather operations, where thinner air costs helicopters some of their lift.
The MD 530F uses Rolls Royce’s 650 shp 250-C30 engine, instead of the 500E’s 450-shp 250-C20R. That drives a 5-bladed set of main-rotor blades that have been extended 6 inches, along with lengthened tail rotors on a correspondingly longer tail boom. In a typical working configuration, at a design gross weight of 3,100 pounds/ 1,406 kg and a useful load of over 1,509 pounds/ 684 kg, it can hover out-of-ground effect at 11,600 feet/ 3,536m (ISA + 20°C). An optional cargo hook is rated for 2,000 pounds/ 907 kg, and the helicopter also has a flat aft cargo compartment floor for internal loads. These may be training helicopters, but they can be repurposed for light utility tasks. MD Helicopter designs are not unknown in the military market.
