Abstract
A system for an icing resistant sensor port assembly includes shaped and patterned features for resisting the formation and propagation of ice around a sensor port, such as for a pressure sensor in an aircraft fuel tank. Water may be present in fuel tanks due to condensation and other factors. The water, being heavier than fuel, such as jet fuel, sinks to the bottom of the tank and may be present around the sensor port. If the water completely fills the pressure port, it may damage the sensor. In various embodiments, an inlet assembly having a cone-shaped countersink, sharp edges that reduce surface area, anti-wetting coatings, and slots to allow fluid flow within the inlet assembly, among other features, may be used to help resist ice formation and propagation around a sensor port.
