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.

System and method for detecting a lubricant-out condition in an aircraft gearbox

A lubrication system for a transmission assembly includes a primary reservoir, at least one primary jet, a primary circulating system fluidly coupling the primary reservoir and the at least one primary jet, a secondary reservoir, at least one secondary jet, and a secondary circulating system fluidly coupling the primary reservoir and the at least one secondary jet and fluidly coupling the primary reservoir and the secondary reservoir.

Low profile auxiliary lubrication system

A lubrication system for a transmission includes a flow-metering device and a controller. The controller is operatively associated with the flow-metering device to cause the flow-metering device to intermittently issue lubricant from the flow-metering device into a transmission based on an operating parameter of the transmission.
