Modernization of the transonic axial compressor test rig
Byrd, Andre E.
MetadataShow full item record
This work presents the design and simulation process of modernizing the Naval Postgraduate School's transonic compressor test rig (TCR). The TCR, which exists primarily for the purpose of testing axial fans at engine test speeds, is driven by an air driven turbine that is in turn driven by a twelve-stage compressor that consumes 1 MW of electric power. This work seeks improved efficiency and decreased maintenance requirements in the system by replacing the turbine drive with an electric drive train. The replacement of the turbine is the first phase in replacing various components of the TCR system, which was built in 1968, with 21st century technology. Solid modeling software was used to accurately create three-dimensional models of the new test rig base, electric drive train housing, and other necessary components. These models were used to fabricate the materials. Stiffness tests and modal analysis were conducted via Finite Element Analysis (FEA) software. This analysis was used to design several iterations of the system. Experimental testing and observation of the system will start once building is complete.
