Abstract: A joist assembly system that is structured for dynamic retrieval of components, dynamic and precise positioning and location of retrieved components, assembly of the components to form a joist, and delivery of the assembled joist. The joist assembly system has a plurality of material handling systems, a plurality of welding systems, and a rigging table system. The material handling systems are structured to load and position the components such as chords and webs onto the rigging table. The rigging table in turn supports the chords or webs. Subsequently, the plurality of welding systems weld the webs to the chords to form the joist.

Abstract: A system includes a bleed system configured to direct a bleed flow from a compressor section to an exhaust section of a gas turbine engine. The bleed system includes a first bleed conduit section configured to couple to the compressor section, a second bleed conduit section configured to couple to the exhaust section, and a first rotatable joint coupling together adjacent conduits of the first and second bleed conduit sections. The second bleed conduit section has components configured to rotate between a plurality of configurations relative to the first bleed conduit section and the compressor section via the first rotatable joint. The plurality of orientations corresponds to a plurality of exhaust outlet orientations of the exhaust section, and the components of the second bleed conduit section are the same in each orientation.

Abstract: A turbine ventilation system includes a controller that is coupled to an actuator that is coupled to a vane that is disposed across an intake port between a gas turbine enclosure and the turbine ventilation system. The controller can cause the actuator to change a position of the vane to alter an air flow from the turbine ventilation system into the gas turbine enclosure based upon feedback from one or more sensors disposed within the gas turbine enclosure.
