QuEST Global NA Foley, AL Sep 2018 – May 2020

Role: MRB Stress Engineer

Project Description:

QuEST Global plays a crucial role in the production process of Collins Aerospace. Collins Aerospace in Foley assembles the various parts of a nacelle for leading aircraft manufacturers Airbus, MRJ and Embraer. Nonconformances sometimes arise from production, which makes parts not suitable for use in the industry. In the event of a discrepancy, several checks are in place to ensure these parts are still within certification limits. QuEST Global provides a team of engineers to support the Material Review Board (MRB) in performing these checks.

Responsibilities:

• Elaborated on new analysis approaches and trade studies to envelope future defects.

• Coordinated technical content and performed additional analyses to ensure acceptance of concessions.

• Performed structural Static and Fatigue analysis of Composite/Metallic nacelle component structure nonconformities using standard analysis methods and finite element analysis using Patran/Nastran to justify the repair or use-as-is disposition.

• Executed stress analysis tasks using hand calculations and FEA software.

• Provided technical recommendations based on engineering judgment.

• Created Technical Documentation and standard work.

• Improved technical and procedural tools, work instructions, etc. to ensure repeatability and reduced execution time by 10%.

• Followed all regulatory and company procedures, including thorough recording of all work to ensure task traceability.

• Communicated with Quality engineers and MRB engineers to propose better alternate dispositions when required. Cleveland State University Cleveland, OH Aug 2016 – May 2018 Graduate Teaching Assistant for Strength of Materials, Dynamics, and Engineering Economy courses for 4 semesters while pursuing master’s degree. Responsibilities held were grading quizzes and helping students with their course work. HCL Technologies Ltd. (at UTC Aerospace Systems) Bangalore, India Nov 2013 – Dec 2015 Role: Stress Engineer

Project Description:

The scope of this project involved Static Analysis and Fatigue Analysis of Electrical System Brackets and Engine Build-up Unit systems, such as BIFI Drain System, Starter Air Duct System, Environmental Control System using combination of hand calculations and finite element analysis.

Responsibilities:

• Studied geometry, and design of systems and prepared finite element models.

• Performed Linear Static Analysis, Non-Linear Static Analysis for various load cases followed by Fatigue Analysis, both High Cycle Fatigue and Low Cycle Fatigue Analysis.

• Mitigated stress at critical locations using troubleshooting techniques.

• Performed hand calculations such as Fastener Analysis, P-clamp Analysis, Lug Analysis, Weld Analysis, Ball Joint Analysis and V- band Analysis.

• Created certification reports compiling static and fatigue analysis to show regulatory agencies requirements compliance. Achievements: Team received Partner Award.

Tech Mahindra Bangalore, India June 2011 – Nov 2013 Role: Junior Stress Engineer

Project description:

Stress dossier preparation for A350 XWB 900 system support assemblies for provided FEM data and related supporting documents. Responsibilities:

• Executed Static, Modal and Buckling analysis for provided Finite Element files using MSC NASTRAN.

• Attached result files and post-processed to report Stress tensor and strain values for individual parts of assembly and calculate margin of safety.

• Extracted internal loads (BUSH forces) to perform hand calculations for fasteners, lugs, and rods.

• Prepared the stress dossier to show regulatory agencies requirements compliance. Project description:

The scope of this project was to perform static strength analysis of Falcon 2000 Interior Cabinets like Galleys, Closets and Arm rest. Responsibilities:

• Performed finite elements analysis of the structural assemblies for various inertial conditions like 1.5G, +3G,-3G, 8.6G, 5.6G and 9G conditions.

• Post processed maximum principal stresses/strains in composite panels and von-mises Stresses in metal brackets, panel pin analysis during the inertial load cases.

• Performed SOL 103 analysis to determine the frequency of the aircraft interiors.

• Carried out joint analysis

• Prepared detailed report for the validation as per FAR/JAR requirements EDUCATION
