Pashilkar, AA (2001) Unsteady aerodynamic modeling at high incidence for flight dynamic analysis. In: AIAA Atmospheric Flight Mechanics Conference and Exhibit, 6-9 Aug 2001, Canada, United States.Full text not available from this repository.
The flow incidence rate model proposed for the unsteady variation of aerodynamic coefficients of a delta wing aircraft is extended to multiple time histories. The model is based on suitable modulation of the static data with lagged incidence rate. The novel modeling structure is shown to be consistent with the static, small amplitude forced oscillations and the large amplitude sinusoidal response characteristics of a delta wing wind tunnel model with sweep angle close to 60 deg. The estimation procedure followed in the modeling is explained. The model is empirical in nature and suitable for flight dynamic analysis and parameter estimation.
