| Abstract: | The helicopter noise prediction system, ROTONET, developed recently in the USA is descriped briefly in this paper. The characteristics and prediction capabilities in every phase of ROTONET system are analyzed, and comparisons of flyover noise are emphasized between measured and calculated values for the MD-500E and SA365 N-l helicopters to explain the validity of the ROTONET system and to evaluate the technology status in the field of helicopter system noise prediction in the USA. Lastly, the Phase IV ROTONET System being developed now and the future work for ROTONET are pointed out. |
