Design, manufacture and test of a bearingless rotor hub for the 24% scale model of the Rooivalk attack helicopter

[摘要] ENGLISH ABSTRACT: This document contains the work done on the bearingless rotor hub for the24% scale model of the Rooivalk Attack Helicopter situated at the CSIR inPretoria. This work forms part of the MSc Ing degree of Johannes Steyn.This work was deemed necessary because of a movement away from the fullyarticulated rotor to one of hingeless and more recently bearingless rotors.The main emphasis of this thesis is to be a technology demonstrator morethan the design of a fully working bearingless rotor hub. With this in mind thefinal design in this report is not an optimal one, but the procedures andmethodology in getting to a design are laid out in this document.To verify the design, tests were identified and created. The procedures forthese tests are also included in this document. For the fatigue test a testbench had to be designed and built. This document also includes the designof this test bench
