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

Figure 13

Temperature change of the pitot tube blocked by glaze ice. At the beginning of the experiment, the initial temperature of the pitot tube is assumed to be . After the water droplets solidified for a period, the pitot tube temperature reaches . At this time, the pitot tube is partially blocked, and the temperature of the pitot tube drops. At , the pitot tube is completely blocked.
