SpletThe Swash Plate block is a model of a swash plate mechanism used in axial-piston hydraulic pumps and motors to convert translational motion of a piston into rotational motion of a drive shaft. The mechanism is a combination of a cylinder block or rotor, with the piston fitted inside, and an angled swash plate.

The stationary (outer) swashplate is mounted on the main rotor mast and is connected to the cyclic and collective controls by a series of pushrods. It is able to tilt in all directions and move vertically. The rotating … Prikaži več 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 … Prikaži več 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 … Prikaži več • Swash plate in the resting position. • A raised swashplate causing negative collective blade pitch and thus down-force. Note that the control arms are on the trailing side of the blades, causing the raised swashplate to decrease the blade pitch. Prikaži več 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 … Prikaži več The swashplate was originally proposed by Russian Boris Yuryev in 1911, though he did not use it on his first helicopter of 1912.
