Abstract
The present invention is a viscoelastic damper assembly for a front frame for a gas turbine engine that is removable, reusable, and retrofitable. The viscoelastic damper is disposed within a strut for damping vibration of the strut caused by airstream pressure pulses from first stage fan blades operating at transonic speeds. The viscoelastic damper can be installed in struts on gas turbine engines already in service or during manufacture. Also, the viscoelastic damper can be easily removed and reused when repairs to the front frame are required.
