Abstract
Prospects for relief of the helicopter' s recognized problems by way of design changes as accompanied by, or resulting from, essential research-type information and understanding are examined. For example, the potential advantages of the nonarticulated rotor system are reviewed and the status of the required steps toward adequate knowledge of loads and dynamics is outlined. Other rotor configuration changes, as well as the basic topics of performance, dynamics, operating problems, and safety are similarly treated. It is concluded that many avenues are now available for basic improvements in helicopters via research and invention, while retaining the basic concept of low disc loadings.
