			Tests include performance, hysteresis, endurance, rotor runout, seal offset Seal inlet air temperatures from ambient to 650°C (1200°F) Pressure differentials from 0 to 1720 kPa (250 psi) Surface speeds to 370 m/s (1200 fps) 215 mm (8.5 inch) diameter rotor or other near sizes Seals tested include labyrinth, brush, and finger types Measurement capability includes seal leakage rate, pressure differential, torque and seal power loss   Above: View of the Turbine Seal Test Rig. The test section is at far right, balance piston housing and torque-meter housing at center, and the turbine is located at the left.     Above: Researchers discuss a seal test on either side of the Turbine Seal Rig test section.   + Return to the branch facilities page...
