Pagination or Media Count:
PWT Tunnel 16T compressor, C1, was operated in a two-stage configuration for the purpose of validating computer predicted results obtained with the COCODEC compressor code. The third rotor row of the three-stage machine was removed and an aluminum shroud was installed to provide a smooth flow passage over the voids created by the blade removal. The compressor was reconfigured to three stages and a verification run was made to ensure that no changes in the compressor performance had occurred during the two-stage modification and the reinstallation of the third rotor row.
