| Summary: | Current research concerned with the aerodynamic instability
of compressors aims at an extension of the operating
range of the compressor towards decreased massflow. In
practice, a safety margin is maintained between operating
point and stability limit to prevent the compressor from going
into stall and surge. In this article, we analyze the behavior
of a 4-stage transonic axial compressor before entering
the unstable range and present an approach to identifying incipient
surge and stall using artificial neural networks. This
method is based on measurements of the unsteady static wall
pressure in front of the first rotor. |
