Abstract

A system for limiting deflection of an exhaust sidewall liner on a variable geometry exhaust duct uses a spacer and a T-bolt. The system connects the exhaust sidewall liner to the static structure on a variable geometry exhaust duct. The spacer includes a chimney having a first side and a second side opposite of the first side, an aperture extending from the first side to the second side, a flange disposed on the first side, and at least one anti-rotation tab disposed on the second side near an edge of the second side. The T-bolt includes an elongated shaft that extends along an axis and having a diameter, and a head having at least one straight edge connected to an end of the shaft. The at least one straight edge engages with the anti-ration tab, thereby preventing rotation of the stud T-bolt about the axis.
