A Systematic Approach to Vibration Analysis for a Gas Turbine Engine.

Abstract

The vibrational phenomena of the Ml gas turbine engine is analyzed from a fundamental/elementary approach based on first principles. Insight was gained on the basic dynamic forces under play in many components and assemblies of an actual turbine engine, with particular emphasis on torsional-spring mass systems. Since very little, if any, analysis of this particular type of engine has been conducted, it was necessary to gain familiarity with the vibratory signatures of this application in order to assess the possible operating modes/normalities of a typical fielded engine. Lumped parameter methods are very good for analyzing individual components and for a snapshot into further areas of investigation. After spectrum analyses will be performed, a detailed investigation can then follow up, premised upon many principles introduced in this report.
