The increasing complexity of gas turbine engines has led to the need to develop smaller components. These small components would allow for easier installation and would be better suited for the needs of the engines. One such component that has become too large for use is the compression seal egress fitting. This fitting is used to seal pressure differentials when routing wires and instrumentation through the walls of the turbine engines. Pratt and Whitney seeks to develop smaller versions than the currently used models, which requires the need for rigorous testing to confirm they are up to standard. This project focuses on creating a testing rig to validate various pressure sealing methods so Pratt and Whitney can test their own egress fittings in the future. The pressure vessel will be able to test fittings to conditions that exceed the normal operating conditions of turbine engines, which will prove their reliability.
