Prediction of axial-flow instabilities in a turbojet engine by use of a multistage compressor simulation on the digital computer [PDF]

A method of estimating the undistorted stall line for an axial-flow compressor by using the digital computer is presented. The method involves linearization of nonlinear dynamic equations about an operating point on a speed line, and then application of ...
