摘要：
An integrated strut and turbine vane nozzle (ISV) (28) has inner and outer annular duct walls (32,30) defining an annular flow passage therebetween. Circumferentially spaced-apart struts (34) extend radially across the flow passage. Circumferentially spaced-apart vanes (46) also extend radially across the flow passage and define a plurality of inter-vane passages. Each of the struts (34) is integrated to an associated one of the vanes (46) to form therewith an integrated strut-vane airfoil (47). The inter-vane passages on either side of the integrated strut-vane airfoil (47) may be adjusted for aerodynamic considerations. The vanes (46) may be made separately from the struts (34) and manufactured such as to cater for potential misalignments between the parts.
