This is in FIG. 5 indicated by the reference numeral 92.
- an optimized suction is achieved, which in FIG. 5 is indicated by the reference numeral 96.
- An optimized suction result means that the angle of attack 86 is at its desired value or in its desired value range.
- test 88 shows that the negative pressure in the Absaugeaus Principleung 82 is above the setpoint (in FIG. 5 indicated by the reference numeral 98), then the power of the blower 54 is reduced. This is in FIG. 5 indicated by the reference numeral 100.
