Stability and Control Handbook for HelicoptersAnalytical methods are presented for determining the dynamic stability and control characteristics of generalized procedures which are considerably simplified through the extensive use of information presented in graphs and charts. These charts are applicable to flight conditions from hover to high forward speeds. The charts for low forward speeds were obtained from the rotor performance data based on classical rotor theory. However, the high-speed charts exclude the major assumptions of classical theory and include blade compressibility, stall, reverse flow, large inflow ratios, etc. The handbook contains information suitable for extensive digital and analog computer studies and also provides rapid procedures for predicting helicopter stability and control characteristics for preliminary design applications.
