摘要： An engine arrangement has a gear assembly that drives a first propeller assembly. The gear assembly is driven by a power drive shaft that joins to the gear assembly at a first side. The engine arrangement has a static conduit that extends along a longitudinal internal cavity of the power drive shaft. The conduit penetrates the gear assembly such that a portion of the conduit projects from an opposing second side of the gear assembly. The engine arrangement has one or more first fluid supply lines routed along the static conduit between a hydraulic pressure power source and the first hydraulic actuator. A first hydraulic rotating coupling is mounted to the projecting portion of the static conduit. The first fluid supply lines fluidly communicate with the first hydraulic actuator via the first rotating coupling.

摘要： A pitch change apparatus comprises a hydraulic actuator for angular displacement of propellers of the propeller assembly. The hydraulic actuator has a piston and cylinder arrangement which defines fine and coarse fluid chambers. Increasing the volume of the fine chamber at the expense of the coarse chamber results in angular displacement of the propellers to a finer pitch. Increasing the volume of the coarse chamber at the expense of the fine chamber results in angular displacement of the propellers to a coarser pitch. The pitch change apparatus further comprises one or more fine hydraulic lines carrying hydraulic fluid to and from the fine chamber, and a coarse hydraulic line carrying hydraulic fluid to and from the coarse chamber. The apparatus further comprises a pressure-sensing check valve which fluidly isolates the coarse chamber from the coarse hydraulic line if the pressure in the coarse hydraulic line falls below a threshold pressure.

摘要： A pitch control mechanism for controlling the pitch of propeller assembly propellers has a hydraulic actuator, main hydraulic fluid supply lines, first back-up hydraulic fluid supply lines, and second back-up hydraulic fluid supply lines. The hydraulic actuator has first and second hydraulic cylinders that each angularly displace the propellers between fine and coarse positions. The main hydraulic fluid supply lines supply fluid to the first and second hydraulic cylinders for operating the hydraulic cylinders. The first back-up hydraulic fluid supply lines supply fluid to the hydraulic cylinder for displacing the propellers to a coarser position. The second back-up hydraulic fluid supply lines supply fluid to the second hydraulic cylinder for displacing the propellers to a coarser position. When the main hydraulic fluid supply lines supply inadequate fluid, the first and/or second back-up hydraulic fluid supply lines can supply fluid for displacing the propellers to a coarser position.

摘要： A back-up featherer is provided for an engine arrangement having a main hydraulic actuator which operates a pitch change mechanism to angularly displace propellers of a propeller assembly of the engine arrangement, the pitch change mechanism and main hydraulic actuator rotating with the propeller assembly. The back-up featherer has one or more back-up hydraulic actuators located on a static structure of the engine arrangement. The back-up featherer further has one or more load application members which are located on the static structure of the engine arrangement and which are movable by the back-up hydraulic actuators. When moved by the back-up hydraulic actuators, the load application members bear against an engagement portion of the pitch change mechanism across a rotating interface formed therebetween to apply a load to the pitch change mechanism which results in angular displacement of the propellers.

摘要： A pitch change apparatus is provided for a propeller assembly having a row of propeller blades which rotate around an axis of the assembly. The apparatus has a unison ring which is coaxial with the propeller assembly. The unison ring is movable to drive respective mechanisms for varying the pitch of the blades. The apparatus further has a plurality of pitch lock assemblies circumferentially distributed around the unison ring. Each pitch lock assembly has a free state which allows movement of the unison ring and a locked state which prevents or limits movement of the unison ring and thus prevents or limits variation of the pitch of the blades. The pitch lock assembly moves from the free to the locked state when the assembly receives a signal to lock the blades.
