Abstract

A pin-guided spring (240) is used for mounting a ceramic matrix composite (CMC) component (210) of a turbine engine, wherein the CMC component having a hot side configured for exposure to a hot gaspath (205) of the turbine engine and an opposing non-gaspath side having a first flange (212) and a second flange (213) extending radially outward therefrom, the first and second flanges each including axial holes (214, 215) disposed therethrough. The pin-guided spring has a first end (352) with first axial holes (460) in registration with the axial holes in the first flange and dimensioned to engage a plurality of pins (220), a second end (354) with second axial holes in registration with the axial holes in the first flange and dimensioned to engage the plurality of pins, and a compressible central section (356) dimensioned for an interference fit between a support and the second flange. The interference fit on the pin-guided spring can protect the CMC component from damage.
