2. Helicopter flight controls - Wikipedia

   en.wikipedia.org/wiki/Helicopter_flight_controls

   During forward flight, the cyclic control inputs cause flight path changes similar to fixed-wing aircraft flight; left or right inputs cause the helicopter to roll into a turn in the desired direction, and forward and back inputs change the pitch attitude of the helicopter resulting in altitude changes (climbing or descending flight).

3. Cyclic/collective pitch mixing - Wikipedia

   en.wikipedia.org/wiki/Cyclic/collective_pitch_mixing

   Cyclic/collective pitch mixing (CCPM) is a control concept employed in collective pitch radio-controlled helicopters. [1] CCPM reduces mechanical complexity and increases precision of control of the helicopter rotor's swashplate. Unlike conventional systems in which a single actuator is responsible for a single axis, CCPM mechanisms allow ...

4. Swashplate (aeronautics) - Wikipedia

   en.wikipedia.org/wiki/Swashplate_(aeronautics)

   To control the collective pitch of the main rotor blades, the entire swashplate must be moved up or down along its axis without changing the orientation of the cyclic controls. Conventionally, each control mechanism, (roll, pitch, and collective) had an individual actuator responsible for the movement.

5. Breguet G.111 - Wikipedia

   en.wikipedia.org/wiki/Breguet_G.111

   The control column alters cyclic pitch via a pair of swashplates and pedals make torque corrections and control yaw by changing the relative collective pitch of the two rotors. A mechanical inertial governor limited rotor accelerations; the pilot could increase the collective pitch over that set by the governor but not below it, emergencies ...

6. Radio-controlled helicopter - Wikipedia

   en.wikipedia.org/wiki/Radio-controlled_helicopter

   Learning to fly a collective pitch RC helicopter takes time and practice. Many modelers join a club so they can be instructed by experienced RC pilots, or follow on-line guides. [12] RC Helicopters usually have at least four controls: roll - cyclic pitch, elevator (fore-aft cyclic pitch), rudder (yaw) and pitch/throttle (collective pitch/power ...

7. Helicopter rotor - Wikipedia

   en.wikipedia.org/wiki/Helicopter_rotor

   To pitch forward and accelerate, both rotors increase the pitch at the rear and reduce the pitch at the front (cyclic) keeping torque the same on both rotors, flying sideways is achieved by increasing the pitch on one side and reducing pitch on the other. Yaw control develops through opposing cyclic pitch in each rotor.

8. Cierva W.9 - Wikipedia

   en.wikipedia.org/wiki/Cierva_W.9

   In 1943, primary investor G & J Weir Ltd. revived the moribund Cierva Autogiro Company to develop an experimental helicopter to Air Ministry Specification E.16/43. The W.9 was to investigate James G. Weir's contention that a powered tilting hub-controlled rotor with automatic collective pitch control, and torque reaction control using jet efflux, was both safer and more efficient than the ...

9. Coaxial-rotor aircraft - Wikipedia

   en.wikipedia.org/wiki/Coaxial-rotor_aircraft

   Coaxial rotors solve the problem of main rotor torque by turning each set of rotors in opposite directions. The opposite torques from the rotors cancel each other out. Rotational maneuvering, yaw control, is accomplished by increasing the collective pitch of one rotor and decreasing the collective pitch on the other. This causes a controlled ...
