A Comprehensive Hierarchical Aeromechanics Rotorcraft Model (CHARM) incorporating fast vortex and fast panel methods for modeling complete rotorcraft has been developed and applied to the problems of rotor/wake/body interaction. The background and technical foundations of this model are reviewed and sample calculations are presented to demonstrate the capabilities of east methods in these modeling applications. Correlations with test data are described that illustrate the performance of the analysis in capturing measured values of average rotor performance, rotor-induced fuselage loading, and wake geometry associated with interactional aerodynamics phenomena. Results suggest that these fast methods can provide good accuracy for a wide variety of key interactional aerodynamics problems with computation times compatible with routine use in rotorcraft design analysis tasks.
