Flutter Analysis of a Transonic Fan [PDF]

open access: yesVolume 4: Turbo Expo 2002, Parts A and B, 2002
This paper describes the calculation of flutter stability characteristics for a transonic forward swept fan configuration using a viscous aeroelastic analysis program. Unsteady Navier-Stokes equations are solved on a dynamically deforming, body fitted, grid to obtain the aeroelastic characteristics using the energy exchange method.
