The Kaman K-MAX has intermeshing rotors eliminating the need for a tail rotor. These opposite-spinning rotors lend the K-MAX a natural tendency to hover, making it more stable. The K-MAX is ideal for precision lifting and placing; it’s valuable to firefighters, construction firms, and the military. Following is a transcript of the video.
This helicopter has dual-crossing rotors for increased precision
The K-MAX uses a unique double rotor system where the two rotors cross each other. Kaman Aerospace calls these “intermeshing rotors.”
Its opposing rotors eliminate the need for a tail rotor. This makes the K-Max lighter and less costly to maintain.
Flaps, like those on a plane wing, are built into each rotor. They give the K-MAX more control than a conventional helicopter.
The K-MAX is the world’s first helicopter designed and certified for external lift operations.
