Abstract
A fan air valve for use in high pressure airflow applications is provided. The described fan air valve embodiments employ a plate with a standoff of a height based on aerodynamic torque. The height of the standoff informs a size of an angle at which the plate is positioned within a respective flow body. The described embodiments result in a fan air valve having a closed flow area that is not much larger than the closed flow area of a valve having a perpendicular plate. The described embodiments avert compression of perimeter ice on a downstream edge of the plate during modulation without requiring software adjustments to address perimeter ice.
