Multi-Fidelity Gradient-Based Optimization for High-Dimensional Aeroelastic Configurations
Autor: Andrew S. Thelen, Dean E. Bryson, Bret K. Stanford, Philip S. Beran
Publikováno v: Algorithms, Vol 15, Iss 4, p 131 (2022)
The simultaneous optimization of aircraft shape and internal structural size for transonic flight is excessively costly. The analysis of the governing physics is expensive, in particular for highly flexible aircraft, and the search for optima using a

In-Situ Residual Tracking in Reduced Order Modelling
Autor: Joseph C. Slater, Chris L. Pettit, Philip S. Beran
Publikováno v: Shock and Vibration, Vol 9, Iss 3, Pp 105-121 (2002)
Proper orthogonal decomposition (POD) based reduced-order modelling is demonstrated to be a weighted residual technique similar to Galerkin's method. Estimates of weighted residuals of neglected modes are used to determine relative importance of negl

Role of wing morphing in thrust generation
Autor: Mehdi Ghommem, Muhammad R. Hajj, Philip S. Beran, Ishwar K. Puri
Publikováno v: Theoretical and Applied Mechanics Letters, Vol 4, Iss 3 (2014)
In this paper, we investigate the role of morphing on flight dynamics of two birds by simulating the flow over rigid and morphing wings that have the characteristics of two different birds, namely the Giant Petrel and Dove Prion. The simulation of a

Aeroelastic Flutter Prediction Using Multifidelity Modeling of the Generalized Aerodynamic Influence Coefficients
Autor: Leifur Leifsson, Andrew S. Thelen, Philip S. Beran
Publikováno v: AIAA Journal. 58:4764-4780
This work proposes a multifidelity modeling approach for predicting aeroelastic flutter of airfoils and wings. Using aerodynamic models based on the doublet-lattice method and time-accurate Euler e...

Multifidelity Sparse Polynomial Chaos Surrogate Models Applied to Flutter Databases
Autor: Markus P. Rumpfkeil, Philip S. Beran
Publikováno v: AIAA Journal. 58:1292-1303
Multifidelity sparse polynomial chaos expansion (MFSPCE) models of critical flutter dynamic pressures as a function of Mach number, angle of attack, and thickness-to-chord ratio are constructed in ...
