Kurzfassung

Modern helicopters still suffer from many problems that hinder a further increase in their efficiency, acceptance and hence their market share. The high level of vibrations and the noise generated by the rotor are the most important rea-sons for this. Vibrations are problematic for pilot and passenger comfort, but give also rise to an increase in maintenance effort. The high noise level limits the acceptance of helicopters in the public, e.g. landing of helicopters on or close to hospitals during Emergency Medical Services missions. High noise levels also lead to an early aural detection during military missions. Further drawbacks of helicopters are the high fuel consumption in high-speed forward flight and hence low range, limited speed of flight, etc. To overcome these drawbacks active rotor control technologies have been investigated for a long time. Many different approaches have been investigated and most of them are not being followed any more. First investigations started with so-called Higher Harmonic Control (HHC) which has been replaced by Indi-vidual Blade Control (IBC). In a previous paper motivation on active rotor control technology was recapitulated as well as achievements on HHC. This paper continues that work and gives a survey on IBC concepts and achievements. An outlook on the idea of the swashplateless helicopter concludes the paper.
