ABSTRACT:
A fuel pumping and transfer system for a multiple concentric shaft gas turbine engine which has the capability to handle contaminated or slurry fuels. The fuel is introduced into the innermost shaft at any desired low pressure thereby eliminating the need for a high pressure fuel pump. Fuel is introduced through a rotating fuel tube disposed within the inner shaft of the engine. The centrifugal force caused by rotation of the shafts causes the fuel to be collected against the inner wall of the shaft creating a centrifugal pressure dam. As the fuel passes from one collection region to the next the differential pressure between the inner shaft region and the combustor increases sufficiently to provide proper combustion.
