Keywords: Helicopter, FSI, maneuver

The present work is focused on the development and application of a CFD/CSD coupled analysis for prediction of helicopter maneuver loads. The analysis will be validated against test data from UH-60A pull-up maneuver. Analysis accuracy will be investigated through correlation of blade loads and rotor performance parameters.
