| The invention is a turbo machine comprising a rotatably mounted blade row, such as a compressing or pumping rotor and apparatus for providing aerodynamic feedback to the blade row which feedback apparatus has substantially zero pressure difference across it. The feedback may be provided by various apparatus, including at least one free-rotor that is mounted in aerodynamic feedback with the blade row, for instance coaxially with respect to the axis of rotation of the blade row and freely rotatably with respect to the blade row. The free-rotor may also be located in ductwork in communication with the blade row. The feedback may also be provided by a blade row having a variable stagger angle and apparatus to adjust the stagger angle so that the mean pressure rise across the variable stagger angle blade row is zero. The invention also includes a method for controlling operating anomalies such as rotating stall and surge of a turbo machine such as a compressor using the above described apparatus. | ||||||

| 84 | Method and apparatus for diagnosing and controlling rotating stall and surge in rotating machinery | US25801 | 1998-02-19 | US6092029A | 2000-07-18 | Donald E. Bently |
| A method and apparatus is provided for diagnosing and correcting rotating stall and surge in rotating machines by monitoring dynamic shaft precession and comparing this precession with a standard and altering the precession as the machine approaches a destabilizing condition when indicated by the comparison step. Axial vibration monitoring means is also provided for monitoring and comparing a dynamic axial vibration of the machine with a standard and altering the axial vibration as the machine approaches a destabilizing condition. Furthermore, the instant invention measures the complex dynamic stiffness of the machine and computes the direct dynamic stiffness and the quadrature dynamic stiffness for use as a destabilizing warning device by monitoring for a drop in direct dynamic stiffness and/or a coincidence of zero crossing of both the direct dynamic stiffness and the quadrature dynamic stiffness components. One embodiment for altering the rotating stall and/or surge is by a controlled active servobearing. | ||||||
| 85 | Process and apparatus for recovery from rotating stall in axial flow fans and compressors | US779151 | 1997-01-03 | US5782603A | 1998-07-21 | Walter F. O'Brien; Anthony L. DiPietro, Jr. |
| Active recovery from a rotating stall operating condition in an axial flow compression system is accomplished by altering the temperature and/or density of the working fluid flowing in the inlet of the compression system once rotating stall is detected. A burner is used to increase the compressor inlet flow temperature and concomitantly reduce the inlet flow density. Alternatively, a low density gas such as helium is injected into the compressor inlet. The ingestion of high temperature gases or other low density gases into the compressor energizes a dynamic response from the compression system that induces rotating stall recovery. | ||||||

| The invention relates to a method for detecting a rotating stall fault in a compressor (12) which is driven by means of a three-phase current motor (8) fed by an inverter. According to the invention, an instantaneous estimated value (^m ) which is calculated from measured power converter output currents (iS1, iS2, iS3) and a measured rotational-speed-proportional signal (ω) is compared with an instantaneous setpoint value (m*) determined from a measured rotational-speed-proportional signal (ω) and a predetermined rotational-speed-proportional signal (ω*), in such a way that in the case of inequality a signal (SRS) is generated which indicates that the rotating stall fault has occurred. In this way, it is possible for the rotating stall fault to be detected without pressure sensors and/or oscillation pickups in a compressor (12) which is driven with a three-phase current motor (8) fed by inverter. | ||||||
