Describing the flight behaviour of the helicopter presents an even more difficult challenge to mathematical modelling. The vehicle can be viewed as a complex arrangement of interacting subsystems. This chapter derives the expressions for the forces and moments acting on the various components of the helicopter; and considers the main rotor, tail rotor (TR), fuselage and empennage, power plant, and flight control system. It presents the combined forces and moments on these elements that are assembled with the inertial and gravitational forces to form the overall helicopter simulation equations of motion. The chapter takes the reader briefly beyond the realms of Level 1 modelling to the more detailed and higher fidelity blade element and aeroelastic rotor formulations and the complexities of interactional aerodynamic modelling. It focuses on the rotor dynamics, deriving expressions for the acceleration and velocity of a blade element and discussing different axes systems used in the literature for describing the blade motion.
