Abstract:The development of a vibration absorber for the reduction of helicopter vibration levels is described. Basic absorber theory is reviewed, and the limitations of such an approach are discussed. Design and development problems are reviewed; final results are also presented. These results show that an absorber installation can effectively eliminate structural amplification of predominant flight vibration frequencies. This can be done with a very small penalty compared to other possible approaches, and without transferring the vibration problem to other areas in the aircraft. Design problems connected with the absorber installation are easily resolved, and service results are satisfactory.
