Abstract
An interference fit up for an HPT hanger is accomplished by machining and casting features into the hanger which create a spring effect when the hanger is assembled into the support. The spring effect may be accomplished in a variety of ways, including offset radial cut features on the hanger relative to the support, or offset projection features on the hanger which are concentric with the support. The spring effect is then accomplished by a flex or deflection of the ends of the hanger to conform to the width of the support, and clearance indentations created during the installation.
