In this paper, a computer based mathematical model for a
teetering-hub, single rotor Bell 205 helicopter model is
constructed with Matlab-Simulink. The helicopter model
consists of a common core of rigid-body dynamics
equations, main and tail rotors flapping dynamics and
aerodynamics, a mathematical model that provides the
aerodynamic forces and moments of fuselage and
empennages, an Earth model to illustrate gravitational
effect and atmospheric parameters, gust model to
illustrate atmospheric disturbances and pilot inputs. A
simulation is done for a high forward speed to investigate
flying qualities of the modeled rotorcraft.
