有2个的！
There are two VBV actuators (referred to as the left and the right actuators).
They are attached to the aft side of the fan frame hub.
NOTE: They have the same design.
The right variable bleed valve (VBV) actuator is on the rear face of the fan frame at the 4:00 position.The left VBV actuator is on the rear face of the fan frame at the 10:00 position
