| Abstract: | The modeling consideration of helicopter air resonance was introduced simply, the analy- sis technique of determining helicopter air resonance safety envelope was studied through calculation examples, and verification method of air resonance through flight test was discussed in this paper. In order to predict safety envlope more cxactly. further reaserch contents and factors need to consider were suggested. Finally it was looked into the furture devlopement of air resonance analysis tech-nique. |
