Abstract
In a gas turbine engine with a bypass duct, a rotating stage of airfoils in the bypass duct is supported through and driven by torque transmitting members extending across the core stream flow path, but which are sufficiently flexible in the radial direction to avoid passing centrifugal loads from the rotating stage across the core stream flow path. The rotating bypass stream stage is also supported through a bearing secured directly to the engine main support structure radially outwardly of the core stream flow path. The majority of aircraft maneuver loads are reacted at this bearing, and a minor portion of the maneuver loads pass across the core stream to a bearing located radially inwardly thereof. The airfoils may be either variable pitch airfols or fixed airfoils. If variable pitch, they may be used to reverse the flow in the bypass duct for thrust reversing.
