Abstract

This report basically presents the research that had been done based on the chosen topic, which is Design of the Detachable Hub for Turbine Blade Cooling. During the time given, research had been done regarding the patented design of hub blade to get the idea of how the hub of turbine blade look likes. In addition, the hub should have the air passage to allow the compressed air to flow through it and exit to the tip of blades. The objective of this project is to design the detachable hub in compliance with all the important factors that already been considered such as engineering requirement and fabrication. The aim of this project is to design the suitable detachable hub for the turbine blade for the test rig. After the design is done, the project also attempts to investigate the hub deformation profile and temperature distribution. The scope of this project covers the planning and designing, material specification, 3D design drawing and the stress distribution and deformation of the hub and blade subjected to a certain loading condition. Throughout this project, Inventor Professional 2009 had been used to design the hub because it more easy and already integrate with the ANSYS simulation software and so investigation of the stress analysis and deformation profile analysis can be done simultaneously. The number of bolt needed has been decide and the bolted joint to couple the hub with the shaft also considered in this project. Material chose is the Carbon steel Ansi 1045. Analysis regarding the deformation happen at the bolted joint; coupler and the fir-tree root blade as well as the thermal distribution happen on the hub also has been investigate. As the conclusion, the analysis done shows the hub design and material choose is fulfill the criteria needed and accepted to be the detachable hub for the internal cooling gas turbine test rig.
