REDUCED MODELS AND CALIBRATION FOR GENERALIZED AEROELASTIC FORCES G.D. Mortchéléwicz

摘要

The generation of state models to simulate aeroelastic forces over time has already led tomany developments. The methods most commonly used are Roger’s or “Minimum State”methods. The obtaining of models with several variables (Mach number, incidence, lift, etc.)and of parameterized models is developed. These models are applied to the calibration ofaeroelastic forces to obtain:1. Given flutter stagnation pressure curves as a function of the Mach number.2. Given frequency response functions (FRF).
