Abstract: A turbine exhaust diffuser adjustment system for a gas turbine engine capable of altering the flow of turbine exhaust gases is disclosed. The turbine exhaust diffuser adjustment system may be formed from one or more flow ramps positioned in a flowpath. The flow ramp may include a downstream, radially outward point that extends radially outward further from the ID flowpath boundary than an upstream, radially outward point that is positioned upstream from the downstream, radially outward point. The flow ramp may be adjustable such that an angular position of a radially outer surface of the flow ramp may be adjusted relative to the ID flowpath boundary, thereby enabling the flowpath to be changed during turbine operation to enhance the efficiency of the turbine engine throughout its range of operation.
