Gas Turbine Aero Engine Rotor Balance and Vibration

Gas Turbine Aero Engine Rotor Balance and Vibration A Description of the Early Problems Encountered by RollsRoyce Ltd., which Led to the Appointment of a Specialist Rotor Balance Engineer, and a Review of the Company's Current Balancing Techniques. THE advent of the gas turbine aero engine brought a state of passenger comfort, never before experienced, into the field of civil air transport this was possible because the unbalanced forces due to reciprocating masses are entirely absent and the purely rotating masses of a turbine engine can, theoretically, be brought into perfect balance. The resulting smooth running engines produce lower levels of passenger fatigue due both to physical effects i.e. a reduced feeling of pins and needles in those parts of the anatomy touching the cabin floor or scat and to aural effects i.e. a lower noise level from engine buzz or cabin panels and fittings resonances. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Aircraft Engineering and Aerospace Technology Emerald Publishing

Abstract

A Description of the Early Problems Encountered by RollsRoyce Ltd., which Led to the Appointment of a Specialist Rotor Balance Engineer, and a Review of the Company's Current Balancing Techniques. THE advent of the gas turbine aero engine brought a state of passenger comfort, never before experienced, into the field of civil air transport this was possible because the unbalanced forces due to reciprocating masses are entirely absent and the purely rotating masses of a turbine engine can, theoretically, be brought into perfect balance. The resulting smooth running engines produce lower levels of passenger fatigue due both to physical effects i.e. a reduced feeling of pins and needles in those parts of the anatomy touching the cabin floor or scat and to aural effects i.e. a lower noise level from engine buzz or cabin panels and fittings resonances.
