Each blade can vary its pitch independently, with the height of the swashplate determining the pitch. With the swashplate sitting flat, pushing the whole thing up and down will change the pitch of all the blades at once.<\/p>\n<p>But with the cyclic control, helicopter pilots are able to tilt the swashplate. Pushing the stick forward, for example, tilts it such that the blades gradually tilt as they spin around, getting flatter as they pass the front of the aircraft, then pitching up to develop more lift as they go around the back. The result is an asymmetry in lift, with more at the back of the disc, and the aircraft pitches forward and accelerates in that direction. The cyclic control can do this in any direction; it\u2019s part of what makes helicopters such dynamic aircraft.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Horizon Aeronautics is prototyping an eVTOL hovercycle concept that uses a complex and interesting split-swashplate \u201cBlainjett\u201d variable pitch rotor system that only exposes half of each fan.
