Description:
The Kaman Aerospace K-MAX is a single-engine, medium-lift helicopter specifically designed to perform external lift of cargo and equipment at extreme conditions. This aircraft is suitable for firefighting, disaster relief, search and rescue, mobilization and logistics, construction/repair of oil rig and pipeline or power lines, and timber harvesting. The aircraft design simplicity has resulted in fewer aircraft systems. Powered by a single Honeywell T53-17 gas turbine that drives two counter-rotating intermeshing two-blade main rotors, the K-MAX can lift up to 6,000 pounds of load while operating at high altitude and hot climate.
The K-MAX helicopter was certified in 1994 and has been sold to customers in 10 countries. Kaman Aerospace has developed the FIREMAX firefighting helicopter based upon K-MAX and fitted out with a water/foam 700-gallon tank.
