ABSTRACT:
An apparatus and process for testing airflow through a turbine vane under actual engine airflow conditions. The apparatus includes first a second static pressure chamber each with an opening on which a cover plate is to be secured to enclose the chamber and hold the vane in place for testing. Each chamber includes a pressurized air supply tube that extends into the chamber to deliver the volume of air necessary for testing the airflow. The chamber is of such a size that the high volume of pressurized air delivered to the chamber will enter the vane as static air for the testing. The cover plates are formed of two halves in which the vane endwall can be secured between the halves. A stand supports both cover plates so that the plates and the vane can be moved into position where the cover plates are secured to the opening of the chamber for testing. The pressurized air supplied to both chambers flows into the vane and through the film cooling holes so that proper testing of the airflow can be done. If a vane has two separate internal cooling passages, each pressure chamber can be supplied with different pressures to simulate airflow conditions through the two different passages.
