Intermeshing twin rotors of a Kaman K-Max Video of K-Max helicopter in flight, showing the meshing main rotors in motion. Intermeshing rotors on a helicopter are a set of two rotors turning in opposite directions with each rotor mast mounted on the helicopter with a slight angle to the other so that the blades intermesh without colliding.
Tandem-rotor designs achieve yaw by applying opposite left and right cyclic to each rotor, effectively pulling both ends of the helicopter in opposite directions. To achieve pitch , opposite collective is applied to each rotor; decreasing the lift produced at one end, while increasing lift at the opposite end, effectively tilting the helicopter ...

The Kaman K-MAX (company designation K-1200) is a helicopter with intermeshing rotors (synchropter) designed and produced by the American manufacturer Kaman Aircraft. Developed during the 1980s and 1990s, the K-MAX builds on the work of the German aeronautical engineer Anton Flettner .
The Fl 282 Kolibri was an improved version of the Flettner Fl 265 announced in July 1940, which pioneered the same intermeshing rotor configuration that the Kolibri used. It had a 7.7 litre displacement, seven-cylinder Siemens-Halske Sh 14 radial engine of 110–120 kW (150–160 hp) mounted in the center of the fuselage, with a transmission mounted on the front of the engine from which a ...
The 'Flettner double rotor' (Sheetintermeshing rotor) is a propulsion system for helicopter, the two rotors used their axes in a low angle tilted against each other. The first helicopter, which this after its developer Anton Flettner notified principle used was in only 6 copies built Flettner Fl 265, the captain of flight Richard Perlia May ...

The design of the Abeille was directed by René Dorand at the helicopter division of SNCAC. An intermeshing rotor layout was chosen instead of a tail rotor design, following the examples of the 1939 Flettner Fl 265 and the Kellet XR-8 of 1944. [1] Its twin, two blade rotors were driven by shafts which leaned out of the fuselage side-by-side ...
