<p>A propeller actuation system (10) comprising: a propeller (12); a propeller control system (24) including a pitch change actuator (26) operatively connected to the propeller (12) for changing a propeller pitch, and a propeller control (30) selectively providing a fluid to the pitch change actuator (26) to change the propeller pitch; an auxiliary tank (45) receiving the fluid from the propeller control system (24); and an auxiliary pump (44) fluidly coupled to the auxiliary tank (45), the auxiliary pump (44) providing the fluid to the propeller control system (24) in response to a pitch change request.
An auxiliary tank (45) is filled by a pitch control system, which enables the size of the auxiliary tank to be reduced.</p> |
