Abstract
A system for passively controlling a variable position guide vane in a turbo-machine. The system includes a shaft rotatable about an axis with an airfoil connected thereto. The shaft is biased toward a closed position, but will open in response to fluid flowing through a flowpath. The guide vane can then be locked in an open position at a desired operating condition of the turbo-machine.
