Abstract:
Apparatus for measuring air pressure acting on a surface of an aircraft during operation comprising:a port in a skin of the aircraft;a cover positioned over the port, the cover having a plurality of small openings, the openings each sized large enough to permit air flow but small enough to deter water and Type II fluids from passing through the openings;a sensing means for sensing a pressure and providing a signal related to the pressure;a port connecting means for connecting the port to the means for sensing so that an air pressure acting on the port is substantially communicated to the means for sensing a pressure; anda housing with a sump chamber for collecting contaminants which enter through the port, the housing having an open end connected to the port in sealing relation therewith and permitting air flow into the sump chamber, an air outlet in the sump chamber, the air outlet connecting the sump chamber to the port connecting means and the air outlet being positioned in the sump chamber such that contaminants from the air entering the port are trapped by the sump chamber while air pressure can still be communicated from the port through the outlet.
