General Characteristics

The Kaman K-MAX is a unique, single-seat, twin-rotor helicopter specifically designed for repetitive external cargo lift operations, essentially functioning as an “aerial truck.” Its key design feature is the use of intermeshing, counter-rotating rotors (a synchropter configuration), which eliminates the need for a tail rotor, directing all engine power to vertical lift.

Property	Typical Value (K-1200)
Úlohu	External Cargo Lift / Aerial Crane
Výrobca	Kaman Aircraft
First Flight	23. decembra 1991
Posádky	1 pilot (single seat)
Max Takeoff Weight (with external load)	5,443 kg (12,000 lb)
Empty Weight	2,334 kg (5,145 lb)
Rotor Diameter (Each)	14.73 m (48 ft 4 in)
Overall Length (Rotors Turning)	15.85 m (52 ft 0 in)

Design and Powerplant

Engine: One Honeywell T53-17A-1 turboshaft engine.
Power Output: Flat-rated to approximately 1,007 kW (1,350 shp) for long life and high-altitude performance, with a thermodynamic rating of 1,800 shp.
Rotor System: Twin, counter-rotating, intermeshing main rotors (synchropter). This design cancels torque without a tail rotor, making the aircraft highly efficient for lift.
Cargo Hook Capacity: 2,722 kg (6,000 lb). The helicopter’s lift capacity is greater than its empty weight.
Control System: Features a unique servo-flap control system on the rotor blades, eliminating complex hydraulics from the main flight controls (though later variants use a blend of systems).
Pilot Visibility: Designed with a narrow, wedge-shaped fuselage and large side windows to provide the pilot with an excellent downward view for precision external load placement (vertical reference flight).

Performance and Applications

Max Speed (Without External Load): 185 km/h (100 knots, 115 mph).
Max Speed (With External Load): 148 km/h (80 knots, 92 mph).
Service Ceiling: 4,572 m (15,000 ft).
Max Range (Normal): Approximately 480 km (300 nautical miles).
Operating Efficiency: Known for its efficiency, requiring less than two maintenance man-hours per flight hour and having a low fuel consumption rate for its lift capacity.
Unmanned Capability: The K-MAX has been successfully deployed as an unmanned aircraft system (UAS) for autonomous cargo delivery, including for military resupply missions.
Typical Applications: Logging, construction (setting utility poles, towers, HVAC units), firefighting (FireMax variant with fixed tank), and military resupply.
