According to one embodiment, a rotary blade actuator includes a housing, a vane disposed within the housing, a shaft disposed at least partially within the housing and coupled to the vane. The vane comprises a first vane surface disposed within a first chamber between a first fluid opening and a second fluid opening and a second vane surface disposed within a second chamber between a third fluid opening and a fourth fluid opening. The first and third fluid openings are configured to provide a first fluid to the first chamber and the second chamber at a first pressure, the second fluid opening is configured to provide a second fluid to the first chamber at a second pressure, and the fourth fluid opening is configured to provide a third fluid to the second chamber at a third pressure different from the second pressure.
