Abstract:
A gearbox assembly for a gas turbine engine used in an aircraft having passive lubrication capabilities during wind milling includes a gearbox housing, a gear train assembly housed within the gearbox housing, a lubricant in the gearbox housing for lubricating the gear train assembly, and a first scavenge port formed in the gearbox housing. The first scavenge port is changeable between an open position and a closed position. Further, the first scavenge port remains in the open position during normal operation of the gas turbine engine to allow the lubricant to drain from the gearbox housing. Upon occurrence of a loss of lubricant pressure in the gearbox assembly, the first scavenge port is changed to the closed position to trap at least a portion of the lubricant in the gearbox housing. Thus, the trapped lubricant provides passive lubrication to the gear train assembly during the loss of lubricant pressure.

Claim (Index 16):
The method of  claim 14 , further comprising determining an amount of lubricant remaining in the gearbox housing after the lubricant pressure drops below the predetermined threshold.
