Abstract
A gas turbine engine case structure includes inner and outer annular case portions radially spaced from one another to provide a flow path and circumferentially arranged airfoils extend radially and interconnect the inner and outer annular case portions. The airfoils include multiple vanes and multiple strut-vanes. Each vane has a vane leading edge. Each strut-vane includes a strut-vane leading edge. The vane leading edges and strut-vane leading edges are aligned in a common plane. The vanes include a first axial length and the strut-vanes include a second axial length that is at least double the first axial length.

A gas turbine engine case structure comprising:
- inner and outer annular case portions radially spaced from one another to provide a flow path;
- circumferentially arranged airfoils extending radially and interconnecting the inner and outer annular case portions, the airfoils including multiple vanes and multiple strut-vanes, each vane having a vane leading edge, each strut-vane including a strut-vane leading edge, the vane leading edges and strut-vane leading edges aligned in a common plane, wherein the vanes include a first axial length and the strut-vanes includes a second axial length that is greater than the first axial length;
- and
- the leading edges of the vanes and strut-vanes are spaced equally apart.
A gas turbine engine comprising:
