In spite of it, cooling of annulus walls and stator vanes requires special attention.
For both stators vane profile, number of vanes, and stagger angle are identical (Fig. 8.22).
Untwisted airfoils are employed throughout the assembly, with stator vanes stacked about the trailing edge and rotor blades at the center of gravity line.
Relative to the trailing edge of a stator vane, the probes are placed at 25 circumferential and 25 radial positions to cover the whole passage between adjacent airfoils.
More homogeneous Mach numbers are observed at 5 and 6 clocking angles, where first stator wake segments reach the midregion of the second stator vane passage.
