Abstract: A helicopter (10) is roll vibration resistant having cantilever spring (40) supported masses (42) located at extreme outboard locations (30). The spring portion (40) extends substantially horizontally and is rigidly secured to rigid structure (28). This vibration absorber (34) is tuned to the forced frequency established by the normal rotor (14) RPM times the number of rotor blades (16).
