Replaceable blade turbine and stationary specimen corrosion testing facility
Technical Report
·
OSTI ID:5736453
A facility was constructed to provide relatively low-cost testing of hot-section turbine blade and vane materials under hot-corrosion conditions more akin to service environments. The facility consists of a small combustor whose pressurized gas flow can be directed to either a test section consisting of three small cascaded specimens or to a partial admittance single-stage axial-flow turbine. The turbine rotor contains 28 replaceable turbine blades. The combustion gases resulting from the burning of Jet A-l fuel can be seeded with measured amounts of alkali salts. This facility is described here along with preliminary corrosion test results obtained during the final checkout of the facility.
