intermeshing rotor

Intermeshing rotors have become noted with Kaman helicopters, which continues this concept.

Intermeshing rotors have high stability and powerful lifting capability.

Intermeshing rotors also turn in opposite directions, but rotate into each other without colliding.

The intermeshing rotors quickly earned it the nickname "eggbeater".

It utilized intermeshing rotors and Kaman's patented servo-flap rotor control.

The H-43 Huskie helicopter uses non-coaxial intermeshing rotors turning in opposite directions.

But like the intermeshing rotors, the transverse rotors use the concept for changes in the roll attitude of the rotorcraft.

In 1951, the Kaman K-225 also used intermeshing rotors with servo-flap control and was the world's first helicopter to be powered by a gas turbine.

Similar to tandem rotors and intermeshing rotors, the transverse rotor also uses differential collective pitch.

Intermeshing rotors are two rotors mounted close to each other at a sufficient angle to let the rotors intermesh over the top of the aircraft.

K-1200 K-MAX - a purpose-built helicopter with intermeshing rotors specializing in external load operations.

The K-125 was Charles Kaman's first helicopter, which utilized intermeshing rotors and Kaman's patented servo-flap stability control.

The Fl 282 Kolibri was an improved version of the Flettner Fl 265, announced in July 1940, which had the same intermeshing rotor configuration as the earlier helicopter.

The Kaman K-MAX (Company designation K-1200) is an American helicopter with intermeshing rotors (synchropter) built by Kaman Aircraft.

Intermeshing rotors - Twin rotors at an acute angle from each other, whose nearly-vertical driveshafts are geared together to synchronise their rotor blades so that they intermesh, also called a synchropter.

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.

While the final product, the Flettner Fl 282 Kolibri ("Hummingbird"), could be factory-assembled, Flettner and Hohenemser insisted that they were the only ones who were capable of assembling the complex intermeshing rotor gearbox assembly.

Kellett's proposal followed the general layout that the company was developing in the XR-8, with twin intermeshing rotors, and was accepted by the Air Force on 16 October over proposals by Sikorsky, Bell, and Platt-LePage.

The Kaman HH-43 Huskie was a helicopter with intermeshing rotors used by the United States Air Force, the United States Navy and the United States Marine Corps from the 1950s until the 1970s.
