The paper presents a model suitable for helicopter flight mechanics purposes. The different components of the vehicle are treated separately, and thus a modular model is obtained. The complete dynamic model is highly nonlinear and is used for trim calculations and calculations of the dynamic response to arbitrary pilot's input, or different external disturbances. Linearization of the model leads to an eigenvalue problem for analyzing the stability of different trim positions. For validation purposes the results of the new model are compared to flight test results and results of other numerical models of the AH-1G Cobra helicopter. Fair agreement is presented, while deviations are discussed and explained.
