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.
