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

Figure 10

Total and static pressure outputs under normal temperature. O–A: the entire detection system is stationary. A-B: after the experimental environment reaches a stable state, 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 point B, the pitot tube is retracted at point B. C–D: the A–B operation is repeated.
