The first link has a picture of some of these vanes: first column, second row.
VIGVs direct air into the first rotor stage. They have the effect of improving the difference between the mass flows at operating points in the mid-range and corresponding surge points (which are catastrophic points at which flow through the stage could spontaneously reverse). Please see the second link and third.

How does electro hydraulic governor functions?
governor has 3 modes of operation 1.SPEED CONTROL MODE-before sychronisation the governor runs in speed control mode.guide vanes open up and the turbine runs in the rated speed.when the governor gets connected to the grid that is when it gets synchronised then the speed control mode terminates. 2.OPENING MODE-load is increased in this mode and teh machine runs in the rated speed only. 3.POWER CONTROL MODE-it has two modes.joint controller and indivisual controller mode.in joint controller mode all the machine works all together and in the indivisual controller one setup point is given to the governor and the guide vanes vary accordingly
What is a CIT sensor?
Compressor Inlet Temperature sensorfor a Gas turbine engine.
What has the author R R Woollett written?
R. R. Woollett has written: 'Effect of variable-inlet guide vanes on the operating characteristics of a tilt nacelle-inlet powered fan model' -- subject(s): Aerodynamics
What is tHe purpose of inlet guide vanes in gas turbine?
In axial flow compressors, the primary purpose of IGVs (fixed or variable) is to guide the airflow onto the first stage rotor blades at an appropriate or required angle of attack.
What is the purpose of guide vanes?
its a water turbine
What is the purpose of hydro guide vanes?
its a water turbine
How Inlet Guide Vanes IGV of gas turbine is calibrated whether it is fist A-aligned or first aligned via angles?
You should consult the control.com website, they have a plethora of information and instructions on how to manually callibrate the IGV of a gas turbine.
What are igv valves?
Inlet Guide Valves
How do you increase efficiency of the centrifugal pumps?
By making it vanes variable direction so that it can work from both side.
What is difference between stall and surge?
stall happen due to too much suction feed but less discharge and will prevent by implemented inlet guide vanes, surge happen due to less suction feed at operating speed and will prevent by intalling recycle line or anti surge line.
What is the runway speed of a hydraulic turbine?
Runway speed is the speed at full opening of guide vanes at nominal head and no load on Generator
How many vanes are in a body?
There are a lot of vanes in a human body. Everywhere you look on your body there probably will be vanes
What are different types of vanes used in centrifugal pump?
there are three major types vanes are used for a centrifugal pumps those are 1.forward curved vanes 2.backward curved vanes 3.flat vanes
Do helicopter engines have a variable guide vane?
Some do.
