Method for determining the flow rate of air through a turbine-engine
labyrinth seal
摘要:
A method for determining the air flow through a labyrinth seal of a turbinengine is disclosed wherein a constant flow rate of an inert gas is injected into the air discharged through the compressor output labyrinth seal. A portion of the gas mixture is withdrawn a specific distance away from the injection point and the flow rate of the air discharged from the labyrinth seal is calculated by measuring the inert gas content of the sample mixture.
