Abstract

The structural integrity analysis of a quill shaft of an aero engine fuel pump is carried out through finite element method. Maximum operating condition, over-load condition to account for any malfunction of fuel control system or over-speed of engine rotors and 400% loading for production acceptance are the three major conditions which have been analyzed for ensuring structural integrity of the shaft. Nodal analysis is also carried out to examine the natural frequency of the quill shaft and to verify that it is in a safe distance from the operating speed of rotating components in fuel pump and gear box.
