VARIABLE PITCH PROPELLER CONTROL SYSTEM

VARIABLE PITCH PROPELLER CONTROL SYSTEM

The variable pitch propeller control system (24) can have a source of adjustable, actuation hydraulic pressure (22), a feather valve (26) openable to provide an actuation path of the actuation hydraulic pressure between the source (22) and the actuator (20), and closeable to connect the actuator (20...

Zusammenfassung:The variable pitch propeller control system (24) can have a source of adjustable, actuation hydraulic pressure (22), a feather valve (26) openable to provide an actuation path of the actuation hydraulic pressure between the source (22) and the actuator (20), and closeable to connect the actuator (20) to a drain (34) below the actuation hydraulic pressure and close the actuator path (30), and a bypass path (36) parallel to the actuator path (30), the bypass path (36) having a restricted flow area (38) relative to a flow area of the actuator path (30).
