- Responsible for launch vehicle integration and structural analysis of spacecraft programs- Verified space vehicle requirements for input to final MSPSP and other range safety documentation in AFPSCMAN 91-710- Coordinated requirements and verification between space vehicle and launch vehicle providers- Worked with internal teams to gather verification evidence for ICD- Assisted in planning launch base activities with launch processing facility and launch vehicle provider- Developed and refined system and component level finite element models for analysis- Performed spacecraft and component level static, sine/random vibration, acoustic, shock analysis per environments provided by customers and launch providers and evaluate margins of safety- Generated reduced finite element models for coupled loads analysis with launch provider- Investigated structural failures from activities such as test and transportation

Worked with: Femap, NX Nastran, MSC Nastran, NX, MatlabStructural analysis for SWOT Project using classical (Bruhn, Roark, etc.) and computational methods (FEA)- Finite element modeling and analysis of several components including assemblies, brackets, harnesses, panels, bondlines.- Completed bolted joint analysis on tension and shear bolt joints using hand calculation methods based on FEA results.- Integrated submodels into system models in Nastran.- Generated and analyzed multiple configurations of spacecraft system from stowed to fully deployed.- Developed loads for static test of components based on system level vibration analysis and supported mentioned static testing.- Conducted a dynamic clearance analysis for a close approach area of concern.- Analyzed detailed potted insert adhesives along the edges of the spacecraft to determine shear and peel stress margins for dynamic launch environment.- Predicted bending angles of composite tube structure due to thermal load.- Modeled contact between ball and cone joint using NX Nastran to match Hertzian contact theory.- Created a Matlab script that formats Nastran OP2 data into a mat file that could be used for post processing in Matlab itself. Used the script to generate maximum stresses in SWOT payload honeycomb panels due to sine input notching.

Launch Systems Engineering- Used MagicDraw for launch vehicle system modeling using data gathered from mission planner’s guides and other sources for a web portal in order to make the information more accessible to those who are planning missions- Modeled constraints in the launch vehicle SysML model to take inputs from a potential mission planner and automatically find a suitable launch vehicle for their spacecraft- Assisted the Asteroid Redirect Robotic Mission (ARRM) in generating and populating launch system related requirements and documents to be delivered to the project and launch service provider

Assistant for Aerospace Structural Mechanics II (ARO 327)

Missile Systems- Assisted in developing a tool that helps engineers quickly and easily access specifications relating to a system; participated in briefing the tool to program leadership and the customer- Read through specification documents in order to determine component reliability, and eventually system reliability- Kept track of the status of multiple trade studies and briefed program leadership weekly- Analyzed a wing spar flange for shear and bearing margins of safety using results obtained from finite element analysis, postprocessed in MSC Patran- Gathered data on propellant finite element analysis to determine alert limits based on strain rate due to loading over a long period of time, postprocessed using Abaqus- Used sets of propellant test data from two different labs to determine the shift factor between the two to bring the two sets of data together- Used Rational Rhapsody to build activity diagrams for requirements flow
