| Abstract | The failure of a quill-shaft in a fan-in-wing model was investigated.
After examination of the available evidence it was concluded that the quill-shaft failure was caused by excessive wear on the inboard pinion bearing, resulting in mal-alignment and large bending stresses in the quill-shaft splines.
No design changes are considered necessary at this time. |
