  • Last chance aircraft back-up hydraulic system
    Patent number: 6845613
    Abstract: A last chance aircraft back-up hydraulic system in which fuel from the fuel tanks of the aircraft is injected into the return line of a leaking hydraulic system by use of a pump activated by a guarded switch by the aircraft's pilot. The fuel serves as hydraulic fluid to operate the pumps of the system as it is injected upstream from the fluid being lost to extend the operating time of the system and prevent failure so the aircraft can be landed at a site.
    Type: Grant
    Filed: November 21, 2001
    Date of Patent: January 25, 2005
    Assignee: The Boeing Company
