Validation and Uncertainty Quantification of Doublet Lattice Flight Loads using Flight Test Data
… The flight loads are computed using a Nastran doublet lattice model and are validated using measured data from a flight loads survey for a Cessna Model 525B business jet equipped with Tamarack® Aerospace Group’s active winglet modification, ATLAS® (Active Technology Load Alleviation System). …

Development of a State-Space Aeroelastic Model of a Flexible T-Tail Aircraft for Flutter Analysis
… coupled fluid structure interaction codes and doublet lattice panel codes. The computation resources and time required for CFD solutions makes them unattractive for preliminary design and doublet lattice models require considerable pre and post processing to provide satisfactory results. Thus, …

An Efficient Reduced Order Modeling Method for Analyzing Composite Beams Under Aeroelastic Loading
… efficient unsteady aerodynamic model such as the doublet lattice method, the dynamic aeroelastic stability can also be efficiently captured. This work introduces a comprehensively verified, open source python API called AeroComBAT (Aeroelastic Composite Beam Analysis Tool). By leveraging …

An unsteady, accelerated, high order panel method with vortex particle wakes
… method potential flow formulations. Source-doublet, doublet-Neumann membrane (doublet lattice), and source-Neumann boundary integral equation formulations are implemented. A precorrected-FFT accelerated Krylov subspace iterative solution technique is implemented to efficiently solve the …

Aeroelastic Analysis of Membrane Wings
… are simulated using a 3-D, free wake, vortex lattice method (VLM), and structural characteristics of the wing are simulated as a membrane supported by a rigid frame. The aerodynamics is validated by comparing the results from the VLM model for constant angle of attack flight, pitching flight …

Effect of Compressive Force on Aeroelastic Stability of a Strut-Braced Wing
… cylindrical function problem. A hybrid doublet lattice/doublet point scheme is devised to reduce the computational time. SBW aircraft selected for the present study is the fuselage-mounted engine configuration. The results indicate that the detrimental effect of the compressive force to …
