Summary of System Retrofits System Retrofits Chilled water Install new control panels for chiller 1-3 system Remove the flow control valves and primary pumps Shut off the isolation valve on the bypass pipeline Boiler system Install two VFDs for FD fans of the two boilers in operation Install two VFDs for the feed water pumps CAV AHUs Lock the inlet guide vane
fully open, shut off the reheat valve and fully open the bypass damper permanently.
All combustion is intended to be completed prior to any flow turning and acceleration caused by the turbine inlet guide vanes
Finally, better controls were incorporated for the inlet guide vanes
to limit HGBP operation.
In these installation, suction throttling or variable inlet guide vanes
are used to provide means of control.
The inlet guide vanes
and first four rows of stator blades on the Cyclone use variable geometry to provide surge control during start-up.
Actuation Systems: JSF actuation systems include the 3 bearing swivel duct actuation system at the rear of the aircraft and the variable area nozzle and inlet guide vanes
, which control airflow through the forward lift fan on the short-takeoff/vertical landing F-35.
fans with new rotor, inlet guide vanes
and delivery gates of two numbers of f.
At a second major inspection (64,000 firing hours) all the following components will be changed: combustion liners, transition pieces, first- and second-stage nozzles, first- and second-stage buckets, first-and second-stage shrouds, inlet guide vanes
, axial compressor blades (stator and rotor), and bearings.
The modulating inlet guide vanes
are made of corrosion-resistant GTD-450 stainless steel to extend their performance life.
There are no hardware differences on an LM6000PC gas turbine for power generation or the mechanical drive applications, with the exception of variable inlet guide vanes
, These components are identical to those used in the DLE version and are required to allow for variable speed operation (see Figure 2).
In a clever use of technology (a technique considered a proprietary secret by the two companies), Boeing and Pratt & Whitney worked together to add stealth to the inlet guide vanes
to mask the fan blades behind them.
