Abstract:
1. A diagnostic system for testing the operation of a first rotary flow device having a variable-geometry mechanism for regulating flow through the device, the system comprising: an electric air flow generator configured to be connected to the rotary flow device to provide a flow of air to an inlet of the device, the air flow generator being configured to provide a flow of air through the device at a predetermined flow rate; a power source in operable communication with the variable-geometry mechanism of the device such that the power source is configured to adjust a position of the variable-geometry mechanism; and a controller configured to selectively control an adjustment of the position of the variable-geometry mechanism, wherein the controller and power source are configured to actuate the variable-geometry mechanism to at least one predetermined position such that an operational condition of the device can be determined according to the flow of air through the device.
