Conventional rotor trim and balance methods rely to some extent on the optical alignment of the blade tips. ROTABS (trademark for Rotor Trim and Balance System), a unique system that tackles the problem at its source by making a multiplane analysis of the airframe vibration characteristics using accelerometers, is described. The system is based on the philosophy that the rotor set up that produces the least vibration will be the best possible combination for performance, comfort and reduced structural fatigue. Vibration levels were significantly reduced from the levels previously achieved by helicopter operators and manufacturers in U.S. and Europe using conventional systems. Future developments are considered.
