REMOVABLE THROAT MOUNTED INLET GUIDE VANE

摘要

In certain embodiments, a system includes an inlet guide vane assembly (102). The inlet guide vane assembly (102 ) includes a plurality of inlet guide vanes (58) disposed in a radial pattern around a central axis (50) and configured to rotate about axes orthogonal to the central axis (50). The inlet guide vane assembly (102) also includes a plurality of vane shafts (106), each connected to a respective inlet guide vane (58) and configured to rotate with the respective inlet guide vane (58) about the respective orthogonal axis. The inlet guide vane assembly (102) further includes a drive shaft (66) directly connected to one of the vane shafts (108) and configured to directly cause rotation of the vane shaft (108) to which it is directly connected and to indirectly cause rotation of the remaining vane shafts (106) in the plurality of vane shafts In addition, the inlet guide vane assembly (102) includes a rotary actuator (60) connected to the drive shaft (66) and configured to cause rotation of the drive shaft (66).
