Abstract
A centrifugal impeller having an inlet and a plurality of outlets, the outlets including at least one outlet in a forward direction of the impeller and at least one outlet in a rearward direction of the impeller. A flow path distance of the outlet in the forward direction can be greater than a flow path distance of the outlet in the rearward direction in order to provide a greater pressure in the outlet having the greater flow path distance. In another embodiment, the flow path volume in the forward direction can be greater than the flow path volume in the rearward direction in order to provide a greater flow volume in the forward direction. In another embodiment, the number of flow paths in the forward direction can be greater than the number of flow paths in the rearward direction in order to provide a greater flow volume in the forward direction. The impeller is also used in a gas turbine engine in which the impeller also includes a turbine blade, and the forward directing outlets deliver compressed air to a combustor while the rearward directed outlets bypass the combustor.
