• Responsibilities encompassed the whole product life cycle, including ideation, prototyping, designing, iterative/FEA/empirical testing and setting up manufacturing.

• Generated surface models of fuselage using Autodesk Inventor and interfaced with fabricator to create class A surface molds.

• Designed prototype thruster and optimized design based on multiple bollard pull tests. Applied result to final production thruster to acheive a 15% increase in efficiency.

• Developed thruster kort nozzle which reduced thruster assembly time and allowed for easy bench testing.

• Optimized overall design of submarines to reduce assembly time from 3 months to 1 month. Major submarine assembly can be fully disassembled in 2 days by 1 person.
