Abstract
A system of an aircraft includes a system pump and a booster pump. The system pump is configured to provide hydraulic fluid to the hydraulic system at a first working pressure. The booster pump is configured to supply hydraulic fluid to at least one boostable actuator at a second working pressure higher than the first working pressure. The boostable actuator is operatively coupled to and configured to actuate at least one flight control surface of an aircraft. The booster pump is configured as a high-pressure accumulator and an accumulator energizer, or as a hydraulic actuator pump and a variable speed motor.
