AOA Sensor Design, Construction, and AdjustmentAOA sensor construction details are summarized in Figure 12. All drawings are to scale. On the left are a number of views and assembly details. Typical vane movements over the full dynamic range are shown in the middle. Various null-adjustment settings are illustrated on the right. The sensor element is locked into place with thread wound around it in a
couple of places and with CA. Figure 13 provides front and back close-up views
of the hall-effect sensor component. The component pins should be trimmed prior
to assembly. The rivet should be hammered down flat to lock the two brass pieces together with enough friction to prevent inadvertent movement but still allow for sensor null-adjustments. Use a flat screwdriver for prying when making null-adjustments. The two pieces should be permanently locked together with a drop of CA after final test flights have been completed.    |
