  • System and method for detecting a lubricant-out condition in an aircraft gearbox
    Patent number: 11512811
    Abstract: A gearbox includes a housing including a lubricant reservoir, at least one gear system arranged in the housing, at least one lubricant delivery passage operable to direct a flow of lubricant from a lubricant reservoir onto the at least one gear system, at least one lubricant return passage operable to guide the flow of lubricant to the lubricant reservoir, and a lubricant-out sensor fluidically connected to the at least one lubricant return passage. The lubricant-out sensor is operable to detect a non-pressure based parameter of the lubricant.
    Type: Grant

  • Anti-clog and non-metallic debris detector for lubrication system inlet
    Patent number: 9316630
    Abstract: A contaminant detection system for use in a fluid distribution system includes a first detector assembly including an inlet housing and detector screen through which fluid in the fluid distribution system passes and a first sensor to detect a first type of contaminant caught in the detector screen; and a second detector assembly including a second sensor which activates when the inlet housing or detector screen is clogged to detect whether the fluid contains a second type of contaminant when the first sensor does not detect the first type of contaminant.
