towards the axis of rotation of the rotor assembly 9 the turbine blade 11 is secured to a rotor 13 by conventional means such as for example a dovetail structure the rotor 13 may be provided with a rotor flange 14 that protrudes from the rotor 13 and angles away from the axis of rotation of the rotor assembly 9 the blade flange 12 and the rotor flange 14 define an opening 15 and a chamber 16 disposed in the chamber 16 is a seal assembly 18 that may include an inner shiplap seal plate 19 the at least one inner shiplap plate 19 may include a rim 21 and an indented portion 23 the indented portion 23 provides clearance between the at least one inner shiplap plate 19 and the rotor flange 14 when the at least one inner shiplap plate 19 is inserted into the chamber 16 the seal assembly 18 has a radial dimension that is greater than the radial dimension of the opening 15 and smaller than the radial dimension of the chamber 16 the seal assembly 18 may also include an outer diameter wire seal 27 and an inner diameter wire seal 29 the outer diameter wire seal 27 and the inner diameter wire seal 29 may be of any of a variety of cross section such as for example circular hexagonal octagonal and the like additionally the outer diameter wire seal 27 and the inner diameter wire seal 29 may be a single filament or multiple filaments braided into a rope the outer diameter wire seal 27 and the inner diameter wire seal 29 may be made of.
