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 to the rotating rotor hub and mainblades. See more The swashplate consists of two main parts: a stationary swashplate and a rotating swashplate. The stationary (outer) swashplate is mounted on the main rotor mast and is connected to the cyclic and collective controls … See more Cyclic controls are used to change a helicopter's roll and pitch. Push rods or hydraulic actuators tilt the outer swashplate in response to the pilot's commands. The swashplate moves in the intuitively expected direction, tilting forwards to respond … See more • Swash plate in the resting position. • A raised swashplate causing negative collective blade pitch and thus down-force. Note that the control … See more 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 … See more The swashplate was originally proposed by Russian Boris Yuryev in 1911, though he did not use it on his first helicopter of 1912. Pescara helicopters (1919–30) are coaxial rotors helicopters, each rotor being controlled by a … See more WebThe torque in a helicopter is generated by the engine driving the main rotor in one direction, which causes the fuselage to spin in the other direction. The tail rotor shaft is horizontally mounted and hence creates it own 'lift' to provide anti-torque. The pitch of the tail rotor gives directional control.

WebWings are curved on top and flatter on the bottom. This shape is called an airfoil. That shape makes air flow over the top faster than under the bottom. As a... WebTo control a helicopter the pitch angle of the main rotor blades must be changed in relation to the air flowing over them. This change varies the amount of lift generated by the blades. Pitch angle is referred to as Angle of Attack when the blade is moving through the air. Main rotor blade control comes in two forms, cyclic and collective . retained earnings liability or asset
