Stability and Control Handbook for Compound Helicopters
Abstract
The handbook contains analytical methods and stability data for determining the dynamic stability and control characteristics of generalized single-rotor compound helicopter configurations. The methods use calculation procedures which are considerably simplified through the extensive use of information presented in graphs and charts. These charts are applicable to articulated, teetering, and hingeless rotor systems and cover a range of 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 information presented is suitable for extensive digital and analog computer studies as well as for rapid manual computations such as required for preliminary design applications.
