Abstract
A remote hydraulic system for an aircraft may provide hydraulic fluid to nose landing gear while being isolated from the main landing gear and other main hydraulic systems of the aircraft. A supply pressure accumulator may be configured to supply hydraulic fluid to a hydraulic load of the nose gear. A pressure sensor may be configured to detect a hydraulic pressure in the supply pressure accumulator. A pump may be in fluid communication with the supply pressure accumulator and configured to switch on in response to the hydraulic pressure below a threshold value. A return pressure accumulator may be configured to store the hydraulic fluid returning from the hydraulic load. The pump may drive fluid from the return pressure accumulator to the supply pressure accumulator.
