An intermeshing-rotor helicopter (or synchropter) is a helicopter with a set of two main rotors turning in opposite directions, with each rotor mast mounted with a slight angle to the other, in a transversely symmetrical manner, so that the blades intermesh without colliding.
The Kaman HH-43 Huskie is a helicopter developed and produced by the American rotorcraft manufacturer Kaman Aircraft. [2] It is perhaps most distinctive for its use of twin intermeshing rotors, having been largely designed by the German aeronautical engineer Anton Flettner.
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 ...
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.
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 ...
The Ingenuity Mars helicopter, the first aircraft to operate and fly on another planet, has come to an end after sustaining damage to one or more of its rotor blades.
The K-125 was Charles Kaman's first helicopter, which utilized intermeshing rotors and Kaman's patented servo-flap stability control. [1] The K-125 first flew on 15 January 1947. The K-190 and K-225 were an improved versions of the K-125, which first flew in April and July 1949 respectively.
