Zusammenfassung:
A new rotor model for helicopters flight mechanics simulation is presented. The rotor dynamics is described using multiblade coordinates. the aerodynamic loads include nonlinear effects such as stall and compressibility. These loads are described as harmonic series. The number of harmonics in the series determines the model accuracy. Thus by changing the number of harmonics from one to a large number, it is possible to obtain models that range between a Tip Path. Plane approach and an accurate blade-element model. The user of the model can very easily change the model accuracy and consequently it efficiency. The new rotor model is investigated and its application for trim and maneuver calculations is presented and discussed.
