| Abstract: | A simple rotor model was developed,and the dynamic characteristic of rotor cone was approximately analyzed. The main influence factor of the distance of helicopter blade-tip and tail beam was determined. Through an accident of rotor striking tail beam,the cause of dangerous adjacent between helicopter rotor and tail beam was investigated. And then how to prevent the dangerous phenomenon was discussed. |
