Seattle, Washington

• Extensive use of NX 12.0 to design and test the aircraft system and validating with structural test report• Conceptualized Instrumentation Rack and LOPA for the Rolls Royce flying test bed and performed structural calculation• Supported designing and testing the customers’ wind tunnel models and familiar with Kirsten Wind Tunnel• Designed a cooling ducting system assembly for the MagniX flight test program

Kent, Washington

• Extensive use of CATIA V5 to design aerospace tools and complex parts per customer (Boeing, Sikorsky, Blue Origin, and SpaceX) specification• Generated engineering drawings with appropriate GD&T techniques to support needs of technicians and customers• Specialized in automated kit cutting table programming (Gerber & Eastman) and laser projection system (LPT & AGS)• Analyzed part measurement and inspection data defects to determine root cause and corrective action• Implemented 5S lean manufacturing method to improve the work environment, process, and safety

University Of Washington

• Experimented different materials for 3D printing to produce various removable iced leading edges • Instrumented SLA printed swept wing ice models with pressure taps for wind tunnel testing• Optimized the geometry of ice shape in NX 10 to be manufactured for wind tunnel testing• Utilized Excel to organize data, transferring to Tecplot 360 EX to visualize test results

University Of Washington

• Coordinated with other teams to verify and confirm the design modification• Led configuration decision, sizing, and weight of the UAV model and the full-scale model• Optimized internal structures of the aircraft to minimize the weight and performed failure load testing• Extensive hands-on experience including fiberglass layup and parts installation• Saved approximately $3,000 by re-using and re-designing the old parts for the new configuration• Extensive use of NX 10 (700 hrs in 6 month) to design the wind tunnel model and the full configuration of the UAV model

University Of Washington

• Tested a liquid bi-propellant motor (Ethanol/Nitrous Oxide) that produces 5lb of thrust• Wrote a MATLAB code to acquire the real-time pressure and thrust data using Arduino• Troubleshooting the ignition control box, using oscilloscope, to solve electrical issue• Designed a doublet impinging jet injector using SolidWorks to upgrade the motor performance (20lb thrust)

University Of Washington

• Designed a hybrid rocket that produces 1,000 lb of thrust and reaches 25,000 ft altitude• Investigated the regression rate of a paraffin granule/HTPB mixture compared to pure HTPB• Gained an experience in use of lathe to manufacture paraffin-wax/asphalt emulsion fuel grain • Performed static tests (2 times a month) with different fuel grains to study their characteristics
