after the inner shroud ring 26 has been secured to the vane structure 24 step 86 sealant is applied to any circumferential gaps between adjacent vane structures 24 step 87 the sealant helps to reduce undesired leakage and flow recirculation and generally forms a non structural bond between the adjacent vane structures 24 the sealant can be a ceramic cement a metallic braze a high temperature epoxy sealant or other suitable material next the outer and inner shroud rings 22 and 26 are machined to desired finished dimensions step 88 at this step the optional honeycomb seal 74 can also be ground to finished dimensions any further finishing steps can also be performed at this step as desired for particular applications for example a timing notch can be formed in the inner shroud ring 26 through milling or electric discharge machining edm moreover the shroud rings 22 and 26 can be optimally segmented as desired fig5 and 6 illustrate a fully assembled stator apparatus 90 fig5 is a cross sectional view and fig6 is a front view of a portion of the stator apparatus 90 as shown in fig6 a plurality of vane structures 24 e g 100 or more vane structures are arranged adjacent to each other in an annular configuration relative to an engine centerline cl between the outer shroud ring 22 and the inner shroud ring 26 a sealant 92 is illustrated between.
