Investigation of dynamic loads on a propeller pitch change mechanism
2009 (English)Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
Abstract [en]

This thesis is primarily a fatigue assessment of internal parts in a controllable pitch propeller hub. A main goal has been to assemble a “design tool” which allows for quick assessments of a number of different propeller hub sizes and applications. To aid this process, a number of finite element analyses (FEA) have been run to provide adjustment factors for basic manual stress calculations, with the purpose of yielding accurate stress results for different geometries without the need to run FEA. Several design improvement suggestions have also been formulated based on the knowledge gained throughout this project.
