applications

Engineering Analyst, Aerojet

Performed static and dynamic analysis on nonlinear materials and

structures for various rockets (Trident, JCM, Javelin, SSST, Orion CEV,

T3, Hell Fire ER, PAC3 CRI, PAC3 MSE and Mk-104). Analysis was done

with SDRC/UGNX, NASTRAN, SAAS and ABAQUS software packages and hand

calculations. Statistical analysis was used to determine the aging

characteristics of several rocket motor grains. Complete stress

analysis was done on several programs with high pressure/high

temperature rocket casings (metallic and composite) and nozzles

(advanced materials). Margins of safety were determined for all

analysis. Familiar with JANNAF requirements.

Project Engineer, Protech

Technical/Project leader for the development of an urban assault door

breaching munition for the Marine Corps. Responsible for the design,

development, test and evaluation of all aspects of the program.

Responsible for communicating progress to the customer with written

documentation and presentations. Responsible for leading a team

consisting of engineers, designers, technicians and support personnel.

Responsible for the development of a high pressure composite pressure

vessel, numerical analysis, failure analysis and computational fluid

dynamics. Analysis was performed to determine the proper design and

configuration for a Small Arms Protective Insert (SAPI) for the bullet

proof vest worn by the US military. Significant ballistic improvement

was obtained.
