Various non-proprietary and proprietary activities, results, and methods for the development of a high-performance jump ski for the company Flyman Skis were completed by the Florida Polytechnic University Engineering Senior Design 2 team members Geoff Doback, Noah Poimboeuf, Troy Hair, and Alan Souto. A first-of-its-kind advanced composite layup was.

• Coordinated/performed thermal and structural analyses in ANSYS, in addition to performing post-test examination, analyses, and reporting.
• Performed analysis on rocket components using finite element analysis and computational fluid dynamics.
• Designed optimum nozzle to idealize performance using Matlab and CAD.
• Developed aerospike nozzle variation.
• Hands-on experience designing and fabricating solid/hybrid rocket motors
• Additively manufactured components such as nosecone and grid fins, and collaborated with aerodynamics/simulations team to test them.

• Synthesized a one-of-a-kind composite used to sustainably capture CO2 for crew capsules in space as a cheaper, simpler alternative to the CDRA system used on the International Space Station.
• Modeled and 3D printed gas cell using to test system efficiency.
• Collaborated with composites researchers to explore options of implementing sample into spacecraft fuselages for enhanced specific strength.
• Paper submitted for publication

• Assisted development of the Space Launch System (SLS) at NASA's Marshall Space Flight Center. Main work included:
• Propulsion thermal and fluid analysis for verification of propulsion systems.
• Developed MATLAB programs for prediction of thermally-induced defects in self-reacting friction stir welded metal alloys used for the SLS core stage.
• Designed Thermal Desktop finite element models that simulated the friction stir weld process and determined the minimum development article width to match thermal effects experienced on high-fidelity production.
• Completed transient thermal analysis of cryogenic Structural Heat Intercept, Insulation and Vibration Evaluation Rig (SHIIVER) 4-meter liquid hydrogen test tank (NASA eCryo Project) which resolved anomaly
• Conducted thermal analyses on LH2 tank based on cryogenic to ambient propellant temperature ranges, with variable tank wall and insulation foam thicknesses.
