The demands of modern agile rotorcraft necessitate the use of high-bandwidth control and actuation systems. The modes currently used for simulation and flight control system design must therefore be extended to cover the range of frequencies which encompass the rotor dynamic, including the dynamics of induced flow. The basic models of inflow using local momentum theory and simple vortices have been examined over a range of frequencies using parameter identification techniques and have been found to be inadequate. This paper presents a model inclorporating a Glauert type of augmentation and uses flight data to justify its validity.
