Summary

Presented herein are the results of experimental and analytical tests to determine the acceptability of a ribbon burner to simulate the environment of the turbine shroud-seal section of the T-700 turboshaft engine. The calculated values reveal that the ribbon burner establishes at least as harsh a thermal environment as is present at any time within the first-stage, high-pressure turbine shroud. Since ceramic-coated test pieces of proposed T-700 ceramic-lined shrouds have endured upward of 2000 cycles within the ribbon burner test rig, the shrouds should be able to endure the thermal demands of the T-700 turbine.
