Abstract
A disc turbine rotor assembly comprised of spaced-apart discs includes means of spacing apart disc members of said rotor assembly, which allow for local variation and radial expansion under various local operating temperatures, without allowing axial deflection, deformation, or excessive warping of the disc material. Spacing means and positioning are provided which maintain desired gaps between planar disc surfaces, and may also establish tangential waves in the disc membranes in order to enhance boundary layer effects. Disc and spacer spokes combine to form a vane-axial type exhaust.
