WORK HISTORY
Jr Designer @Safran
Ajax, ON, CA
Part of the Landing Systems division with CGP and ITAR clearances. Design development of military landing gears for the FLRAA (future long range assault aircraft) program (June 2023 ~ Present)• Collaborated with stress and performance teams on component selection and sizing to drive hydraulic fluid system designs• Performed stack-up analyses and applied DFM/DFA principles to ensure proper fit, form, function of a hydraulic actuator while satisfying manufacturing requirements and industry standards• Developed a bushing-to-lug interference fit analysis tool that automated tolerance extraction from lookup tables, collectively reducing analysis, modeling, and drawing creation times by >50% while improving accuracy (Excel)• Developed and updated 3D CAD models (parts, assemblies), produced model based definition, detailed part drawings with GD & T, assembly drawings with stages of operation, and performed PDM configuration control to support design, analysis, manufacturing and test activities (CATIA, Smarteam)• Projected the raw material volumes required for part machining and the number of titanium fretting test coupons that can be extracted from spare parts based on machining guidelines (CATIA, Excel)Assisted sustainability for Bombardier, Mitsubishi, and De Havilland landing gears (Jan 2023 ~ June 2023)• Documented change notices for clients upon reviewing design change requests and the corresponding drawings with GD & T from the engineering change board• Performed change impact analysis to evaluate the effects of design changes on the product fit, form, function, manufacturability, serviceability, verification and validation (V&V) artifacts • Evaluated the fit and function of landing gear parts considering thermal effects by performing tolerance stack-up and statistical tolerance analysis• Consulted with clients, engineers, and the product support team to finalize engineering changes
