Does the compressor stationary vane have stagger angle? ( stagger angle is the angle between chord of the blade or vane with engine's longitudinal axis )
The stationary compressors are responsible for guide the air particles flow to the next compressor or stage with an even air flow on the engine's longitudinal axis, taking under consideration angle adjustments in order to avoid air turbulence with may cause a compressor stall.
So, depending of the engine project, the answer is yes. The angle can variate, being static or even with self-adjustment.
Or, it can be variable. One of the great advances made with the GE J79 was a variable angle stationary vane setup.
