Stiffness of Straight and Tapered Annular Gas Path SealsSource: Journal of Tribology:;1979:;volume( 101 ):;issue: 003::page 349Author:David P. Fleming

Abstract: Radial stiffness of annular (ring-type) gas path seals is calculated for both constant-clearance designs and tapered designs for which the inlet clearance is larger than the outlet clearance. Under some conditions a constant-clearance seal can have a negative stiffness; this undesirable property can be completely eliminated by use of tapered seals. Leakage rates are only moderately higher in tapered seals.
