3801 S Oliver St, Wichita, Ks, Us

Reviewed, approved, performed stress analyses of CH-53K Sikorsky Helicopter structures. Performed and documented detailed stress and fatigue analyses of 787-8, -9 cab structure: windows, frames, posts, sills, extensions, header beam, forward pressure bulkhead, and all joints. Identified areas of structural concern, improved load paths and reduced weight. Provided support for transparency birdstrike tests. Created templates to calculate static-equivalent birdstrike loads and perform ultimate static, thermal, and fatigue analyses to size cab structure. Reviewed and approved detail parts and installation drawings. Updated and revised Patran FEM properties and performed trade studies. Proposed weight improvements to significantly reduced primary structure weight. Traveled to third-party vendors to implement weight reduction efforts.

Blagnac Cedex, Fr

Strength-checked A330 wing rib T-fittings that attach the ribs to wing skins. Used excel templates to extract internal loads and document stress analysis results. Improved the T-fitting analysis template to include explanations of the input parameters which are required to perform the analysis.
