Abstract
The end wall of the compressor adjacent the stator vanes and compressor blades is configured so that the annular region between the vanes and blades is held at a constant area and that the flow path convergence of the stator is increased to compensate for the loss of convergence due to the reduction of convergence in the annular region between vanes and blades.
