* I support the NASA CCP Propulsion, where I confirm that the CCP Spacecraft Developers (Boeing/SpaceX) have properly satisfied NASA's requirements for designing and developing a safe design for Human Spaceflight. Additionally, I assess whether any anomalies, failures, and issues are resolved to NASA design standards.I have developed and continue to improve mission support tools that allows NASA CCP Propulsion personnel to track how issues and failures impact to the Boeing CST-100 Starliner Crew Module (CM) and Service Module (SM) Propulsion Systems.I am managing the team review of Propulsion Hardware Testing, both Qualification and Acceptance Testing, versus design and safety requirements for Commercial Crew Program.

(Part 2 Description)For functional failures resulting in a loss of Thermal control, in-depth understanding of the various design considerations were required design sizing and over / under- temperature protection design controls.* HTX Sizing to support the heat loads collection / rejection. Airflow controls including hardware, software, firmware, and power controls.* Pump design consideration and relief function for flow controls. Bellows function for supporting pump inlet condition protection design controls.* Software and firmware design controls for failure protection.* Radiator design considerations for the worse case thermal environment.* Water sublimation design controls for heat rejection.* Freon cooling system design considerations.Developed Operational Controls for CST- 100 Starliner to protect against specific hazardous conditions.Developed multiple Commercial Crew and ISS design requirement Variances and Non-Compliance Reports (NCRs), requiring detailed assessments and mitigations to accept equivalent or increases in risk to Crew and Vehicle

Loudon, Tn

* College Student Employee – Engineering Department * Converted and updated paper mill’s Computer Aided Design (AutoCAD 2000) database to corporate standards. Learned to interpret engineering drawing data. * Used CAD to design safety guards for manufacturing equipment. These guards became the standard design for future safety guards that are still in use to this day.
