Modelling of A Helicopter System

This paper considers modelling and simulation study of a helicopter system – UH-60 Black Hawk helicopter. Mathematical model of single main rotor helicopters is presented in this paper. For the convenience of presentation, force and moment expressions of the various helicopter components are given in the paper to bridge a generic model to the model of UH-60 Black Hawk helicopters. For simulation study a UH-60 like Flightlab GRM model (Generic Rotorcraft Model) is used. Comparisons are made between the simulation results and flight test data. A general agreement exits but where disagreements and anomalies occur, clues are gathered to give explanation. Overall the model represents the UH-60 Black Hawk helicopter. This model can be used for controller development to improve flight handling quality and performances.
