C/SiC Component & Material Analysis, Attachment Verification, & Blisk Turbopump Testing

Ceramic composite blisk components constructed of carbon fibers & silicon carbide ceramic matrix have been fabricated and tested. Room and cryogenic torque testing have verified the attachment configuration. The polar and quasi-isotropic blisks have been proof spun, balanced, and tested in the Simplex turbopump. Foreign particle impact analysis was conducted for C/SiC. Data and manufacturing lessons learned are significantly benefiting the development of the Reusable Launch Vehicle's ceramic matrix composite integrally bladed disk.
