Pitot Tube-Based Icing Detection: Effect of Ice Blocking on Pressure

Figure 9

Total and static pressure outputs of the pitot tube after blocking by non-ice materials. O–A: the entire air pressure detection system is stationary. A–B: the L-shaped pitot tube is placed into the ice wind tunnel at point A such that the total pressure hole is facing the incoming wind direction. After B: the rubber sleeve is installed on the total pressure hole of the pitot tube at point B.
