Flight dynamics model of helicopter based on Simulink

Abstract

In this paper, a complete numerical simulation model of helicopter flight dynamics was established. The modeling of the main aerodynamic components of the helicopter and the aerodynamic interference are taken into account, and the modeling methods of the airfoil aerodynamic model, the induced velocity model and the waving movement model are discussed in detail. Based on the hierarchical and modular modeling principles, the whole simulation model is finally realized on the Simulink platform. Finally, the model helicopter data are used to prove the rationality and validity of the modeling theory and method.
