Abstract

In some examples, an aircraft gearbox (300) comprises a housing (302), a barrier (314), a rotatable drive system component (308₁), a set of gears (308₂), and a lubrication system (304). The barrier (314) separates a first compartment (306₁) and a second compartment (306₂) within the housing (302). Each of the rotatable drive system component (308₁) and the set of gears (308₂), operable to rotate based on torque received from an engine. The rotatable drive system component (308₁) is located in the first compartment (306₁). The set of gears (308₂), is located in the second compartment (306₂). The lubrication system (304) comprises a first lubrication subsystem (310₁) and a second lubrication subsystem (310₂), which are, at least in part, independent from one another. The first lubrication subsystem (310₁) is operable to lubricate the rotatable drive system component (308₁) in the first compartment (306₁). The second lubrication subsystem (310₂) is operable to lubricate the set of gears (308₂), in the second compartment (306₂). The barrier (314) inhibits lubricant from passing between the first compartment (306₁) and the second compartment (306₂).
