SUMMARY:Data-Driven Modeling of Unsteady Aerodynamics Using Constrained Opt
 imization and Random Input
DESCRIPTION:Lecturer:Tamir Gazit\n Faculty:The Stephen B. Klein Faculty of 
 Aerospace Engineering\n Institute:Technion – Israel Institute of Technol
 ogy\n Location:Classroom 240\, 1st floor\, Aerospace Eng. building\n Zoom:
  https://technion.zoom.us/j/98372598857\n Abstract: A data-driven methodol
 ogy is proposed to identify linear unsteady aerodynamic reduced-order mode
 ls (ROMs) for flexible structures. Constrained gradient-based optimization
  extracts aerodynamic stiffness\, damping\, and time-domain convolution ke
 rnels directly from input-output data. Training data is generated efficien
 tly via a single computational fluid dynamics (CFD) simulation using simul
 taneous band-limited white noise excitation across all structural modes. A
  custom loss function enforces physical kernel smoothness and temporal dec
 ay\, while a spectral coherence metric assesses data linearity to establis
 h excitation bandwidth limits. Validated against linear potential flow and
  coupled Euler flow simulations for a clamped plate in supersonic flow (Ma
 ch 1.2–1.94)\, the extracted ROMs accurately predict flutter onset and p
 ost-flutter limit-cycle oscillations. The approach demonstrates high scala
 bility\, successfully identifying a 16-mode\, 50\,000-parameter system whe
 re classical least-squares methods fail. Finally\, the method is applied t
 o a plate with an impinging oblique shock to compute nonlinear aeroelastic
  stability boundaries\, which are validated via direct comparison with cou
 pled Euler flow solutions.\n\nThis work is towards an M.Sc. degree under t
 he supervision of Assoc. Prof. Maxim Freydin\, Aerospace Engineering\, Tec
 hnion.\n Details: \n
