<p>A method of testing a hollow rotary component for which centrifugal loading is the principal in service load comprises internally pressurising the component to a pressure at which the stresses caused by in service centrifugal loading are replicated within the component. Apparatus for testing comprises a pressure rig 20 able to fixedly mount the component 10 and pressurising means. The apparatus comprises base plate 22, top plate 24, seal 28, struts 26, and support ring 30. The component may be a turbine engine nose cone or other hollow component subjected to rotation in use.</p> |
