Abstract:
An apparatus is provided in a gas turbine engine for eliminating air leakage-induced vibration at natural frequencies in a type of flexible annular seal structure sometimes referred to as a floating fishmouth seal. A floating fishmouth seal has male and female sections arranged to permit axial and radial movement and still maintain a sealing relationship. In a preferred form, the apparatus for eliminating air leakage-induced vibration includes two structures that interact with the male and female sections of the fishmouth seal during engine operation. The first structure is an annular leaf spring assembly that presses a radial flange of the male section of the seal against a stationary wall to obtain frictional damping. The second structure is an annular member attached to an outer surface of the female section of the seal forming a closed-in structure to provide stability and damping. The combined effect of the two structures is to increase the operational life of the fishmouth seal.
