System identification of aerodynamic models

Abstract:

In Chapter 2 it was determined that a nonlinear multibody model was needed to describe the flight dynamics of the ornithopter. In Chapter 3 the rigid body equations of motion, as well as the gravitational effects, were derived from first principles. The aerodynamics for an arbitrary flapping wing vehicle are difficult to model analytically, and are determined in this work using system identification methods with experimental data. This chapter begins with a presentation of the system identification methods employed herein. Afterwards, tail aerodynamic models are identified from wind tunnel data, and wing aerodynamic models are identified from flight test data. This chapter concludes the ...
