Future requirements for helicopters will place still greater emphasis on those features of the helicopter which make for simple, low cost, and effective operation. Some research necessary to meet these needs is described in the current paper. The requirements for low cost operation are reviewed. This implies a considerable improvemnnt in fatigue life, time between overhauls, and in general maintainability of the aircraft. This can be achieved by the intelligent use of new materials and a move towards on-condition maintenance of major components. Many of the operational targets for future helicopters can be set by engineering application of principles which are substantially understood at the present time. Two important exceptions to this are noise and icing. Basic features of external and internal noise are reviewed and recommendations for future work put forward. Icing research is reviewed in the light of recent British activity.
