Abstract
The cavity between the first stage and second stage turbines of a gas turbine power plant is sealed by a rotating seal characterized by an I-beam section annular member spanning therebetween to transmit the axial load through the upper rim and the radial load through the lower rim of the annular member. A hammer head eccentrically mounted on the edge of the upper rim locks in the first stage rear side plate and a gap between the lower rim and second stage turbine pressure balances the I-section.
