Abstract


Compared to fixed wing aircraft, the dynamics of rotorcraft are significantly more complex. One of the major challenges in the design of autonomous helicopter is the development of a flight dynamic model which can be useful for simulation studies and for the design of control law and navigational aspects. There is always a tradeoff between the accuracy of the mathematical model to the physical model as far as the helicopter rotor/fuselage dynamics is concerned. Since the small scale helicopters posses a higher bandwidth of dynamics, models developed from first principle alone do not fulfill the needs, sophisticated mathematical models are required. The main objective of present work is to improve the parameterised identification model by replacing with a most general flight dynamic model, for a mini helicopter. This model includes the rotor blade flap dynamics, stabilizer bar dynamics, and vehicle dynamics which will be applicable for a general maneuvering flight.
