Abstract:The mathematical model of helicopter flight dynamics is the basis for the design of the flight control system, and is also the tool for the design and assessment of helicopter flight quality. As the helicopter is a multi-body system, the mathematical modeling of helicopter flight dynamics should consider the coupling between motion, inertia, structure and aerodynamics, as well as the unsteady and nonlinear characteristics, so as to give the physical meaning and mathematical expression of each motion part. Therefore, the mathematical modeling of helicopter flight dynamics is a complicated process of analyzing and synthesizing different hypotheses and subsystem models. The paper reviews briefly the development of the flight dynamic modeling of the helicopter with a main rotor and a tail rotor. The emphasis is put on the modeling of main rotor aerodynamics, and aerodynamic interaction among the rotor, fuselage and tail rotor. Integrated modeling of the main rotor and engine, as well as the research on maneuver flight, is also the focus of the paper. Suggestions for future research on helicopter flight dynamic modeling are also provided. © 2017, Press of Chinese Journal of Aeronautics. All right reserved.
