  2. Helicopter - Wikipedia

    en.wikipedia.org/wiki/Helicopter

    A helicopter has four flight control inputs. These are the cyclic, the collective, the anti-torque pedals, and the throttle. The cyclic control is usually located between the pilot's legs and is commonly called the cyclic stick or just cyclic. On most helicopters, the cyclic is similar to a joystick.

  3. Helicopter flight controls - Wikipedia

    en.wikipedia.org/wiki/Helicopter_flight_controls

    A typical helicopter has three flight control inputs: the cyclic stick, the collective lever, and the anti-torque pedals. [2] Depending on the complexity of the helicopter, the cyclic and collective may be linked together by a mixing unit, a mechanical or hydraulic device that combines the inputs from both and then sends along the "mixed" input ...

  4. Helicopter rotor - Wikipedia

    en.wikipedia.org/wiki/Helicopter_rotor

    On a helicopter, the main rotor or rotor system is the combination of several rotary wings (rotor blades) with a control system, that generates the aerodynamic lift force that supports the weight of the helicopter, and the thrust that counteracts aerodynamic drag in forward flight. Each main rotor is mounted on a vertical mast over the top of ...

  5. Tail rotor - Wikipedia

    en.wikipedia.org/wiki/Tail_rotor

    Tail rotor. The tail rotor is a smaller rotor mounted vertically or near-vertically at the tail of a traditional single-rotor helicopter, where it rotates to generate a propeller -like horizontal thrust in the same direction as the main rotor 's rotation. The tail rotor's position and distance from the helicopter's center of mass allow it to ...

  6. Helicopter dynamics - Wikipedia

    en.wikipedia.org/wiki/Helicopter_dynamics

    Its comprises helicopter aerodynamics, stability, control, structural dynamics, vibration, and aeroelastic and aeromechanical stability. [1] By studying the forces in helicopter flight, improved helicopter designs can be made, though due to the scale and speed of the dynamics, physical testing is non-trivial and expensive.

  7. Swashplate (aeronautics) - Wikipedia

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

    5. Control (roll). 6. Linkages (silver) to the rotor blade. In aeronautics, a swashplate is a mechanical device that translates input via the helicopter flight controls into motion of the main rotor blades. Because the main rotor blades are spinning, the swashplate is used to transmit three of the pilot's commands from the non-rotating fuselage ...

  8. Coaxial-rotor aircraft - Wikipedia

    en.wikipedia.org/wiki/Coaxial-rotor_aircraft

    A Ukrainian Navy Kamov Ka-27. A coaxial-rotor aircraft is an aircraft whose rotors are mounted one above the other on concentric shafts, with the same axis of rotation, but turning in opposite directions (contra-rotating). This rotor configuration is a feature of helicopters produced by the Russian Kamov helicopter design bureau.

  9. NOTAR - Wikipedia

    en.wikipedia.org/wiki/NOTAR

    NOTAR ("no tail rotor") is a helicopter system which avoids the use of a tail rotor. It was developed by McDonnell Douglas Helicopter Systems (through their acquisition of Hughes Helicopters). The system uses a fan inside the tail boom to build a high volume of low-pressure air, which exits through two slots and creates a boundary layer flow of ...
