R H Swan: 914. Rotary Wing Head Weight Prediction. 1972.



A semi-empirical rotary wing head empirical trend is presented and its development discussed. The method is tailored for use in the early preliminary design and parametric study phases of aircraft development. Major design loads and their sources are discussed. Parameters used in the correlation factor are defined and the rationale for their section is given. Rotary wing head composition is defined and drawings of articulated, teetering and hingeless designs are shown. A summary tables lists the weights and parameters used to derived the trend curve
