Figure 56: Flow at 10 knots around Dual T50 with Fairings
Figure 57 is a cross section of the symmetry plane of the T50 dual head. The front fairings and
bracket assure a steady water flow around the receivers and projectors. The same situation
without front fairings is shown in
Figure 59 .

Figure 56 illustrates the flow at 10 knots around
the T50 dual head with front fairings. The drag on
the pole, sonar heads, and bracket is in the region
