摘要： A coaxial, dual rotor system includes a first rotor assembly located at a rotor axis and rotatable thereabout and a second rotor assembly located at the rotor axis radially inboard of the first rotor assembly and rotatable thereabout. A rotationally fixed static mast is located radially between the first rotor assembly and the second rotor assembly. A transmission includes a rotor input shaft including a first sun gear and a second sun gear. A star gear arrangement is operably connected to the first sun gear and to the static mast to drive rotation of the first rotor assembly about the rotor axis and a planetary gear arrangement is operably connected to the second sun gear and to the static mast to drive rotation of the second rotor assembly about the rotor axis.

摘要： A gearbox assembly includes a housing with a housing interior. A sump is disposed within a lower region of the gearbox housing. A lubricated transmission element is arranged in the housing interior above the sump. A lubricant impoundment is arranged within the housing and in series between the transmission element and the sump such that lubricant flowing in a primary lubricant flow path between the transmission element and the sump is impounded in the lubricant impoundment, thereby providing a supply of lubricant for a secondary lubricant flow path disposed within the gearbox housing.
