Abstract: In a machine such as a turbine generator with a rotor whose end turns are covered by a continuous retaining ring, axial blocks and support blocks are used in an end turn bracing system with the axial block supported by the support blocks at intermediate locations and with openings through the axial blocks at those locations that have a greater axial extent than the support blocks and permit axial gas flow that avoids obstruction by the support blocks. The support blocks are provided of laminated material whose laminations run continuously throughout both major and minor legs of their L-shaped cross-sectional configuration to avoid delamination due to stresses encountered in operation.

Abstract: A method and a gage for time-resolved skin-friction measurements. The gage is a composite structure comprised of a heated, flush-mounted, guard film and a hot wire mounted to an electrically insulated very low thermal conductivity material plug in the vicinity of the film and raised slightly above the plug surface. When the so constructed gage is calibrated in a laminar flow environment, it then has the ability to provide accurate readings of skin-friction in turbulent flow conditions.
