Collaborated with a commercial software vendor to develop and demonstrate an innovative nonlinear aeroelastic analysis. Performed evaluation of Stanford University Unstructured CFD code for a client, building and debugging the software on both a workstation and HPC cluster.Performed structural dynamic, aeroelastic, and dynamic loads analysis of the Learjet 70/75 on a contract basis. Utilized both customer proprietary and Nastran aeroelastic models for the analysis. Wrote the test plans for the certification ground vibration and flight flutter testing. Documented compliance with 14 CFR Part 25.629.Performed finite element analysis of wind turbine blades using ANSYS on a contract basis. Developed software to parametrically generate the finite element model for ANSYS. Developed software to calculate the effective 3D orthotropic composite laminate properties from the 2D in-plane test data. Developed software to evaluate the composite laminate using the LaRC03 multi-mode failure criteria.

Performed flutter and dynamic loads analysis of a business jet modified with wing and fuselage stores. Performed static and dynamic loads analysis of a twin turboprop, carrier based, AEW aircraft using both customer proprietary and Nastran aeroelastic models. Performed modernization and enhancement of the customer proprietary 6DOF simulation code, balanced loads code, and doublet-lattice code. Performed CFD to generate a loads aerodynamic database for a clean-sheet regional jet.

Through testing and finite element analysis, demonstrated the use of anisotropic carbon/glass hybrid composites in wind turbine blades to achieve twist bend coupling of the blades for passive load alleviation at the National Institute for Aviation Research. Demonstrated the use of hybrid composites in improving the shear web buckling characteristics of a composite I-beam representative of a wind turbine spar. Demonstrated the correlation between extension-shear coupling at the laminate level with bend-twist coupling at the blade level.
