The present disclosure relates to a hydraulic power pack arrangement that can be configured in multiple different mounting configurations. The hydraulic power pack arrangement can include a bracket assembly for mounting a hydraulic power pack core assembly and a hydraulic reservoir assembly at a mounting location such as a floor, wall, or ceiling of an aircraft.

An electronic pressure compensated hydraulic motor pump is controlled to provide variable output power based on a variable input signal. The variable output power feature allows the motor pump to be used with a power management system to better match the output power of the motor pump with the available power of an electrical system. The ability to provide variable output power provides beneficial power management for electrical systems that switch between different power modes, e.g., between a generator power mode and a battery power mode.

The left and right main landing gears on an aircraft are normally controlled by separate hydraulic power packs (HPP). Each HPP is sized for the load of the respective main landing gear. During failure of one of the HPP, a backup valve actuates to allow the other HPP to operate both main landing gears. With the backup valve actuated, the pump of the functioning HPP is coupled to the reservoirs of both HPPs and to the load paths to both main landing gears.
