MTU Aero Engines North America

Structures Engineer | January 2017 – Present

Rocky Hill, CT

Projects Include:

  • GE Gas Power Midshaft and Turbine Rotor Redesign – 7HA.02 and 9HA.01 Gas Turbines. Built and owned the 3D bolted joint submodel, updated it as geometry and thermal inputs changed through numerous iterations, and ultimately provided final LCF, Creep, and HCF results. (ANSYS/APDL, Perl, VBA)
  • PW1100G Compressor Airfoil Stress Testing – Set up an on-site strain gauge monitoring plan to support MTU Munich colleagues who couldn’t come to the U.S. due to COVID-19.
  • PW1000G Turbine Rotor Repairs – Analysed structural impact of proposed surface blend repairs, hole re-sizing, and snap-surface restoration repairs mostly for PW1500G and PW1100G Low Pressure Turbine Rotors. Wrote Engineering Authorizations for each repair. (ABAQUS, hand-calcs)
  • Undisclosed Customer – High Pressure Compressor LCF and Fracture lifing (ANSYS/APDL, Python, ABAQUS)
  • PW1100G-JM High Pressure Compressor Redesign – Lead structural analyst for a rotating secondary flow component.  Redesign solves an HCF issue, analysis shows that Goodman consumption is cut in half.  Verification testing to begin in Spring 2020 (ANSYS/APDL)
  • PW1200G Low Pressure Compressor Redesign –  Rotor LCF and Fracture lifing, Airfoil HCF re-tuning (ANSYS/APDL, NX)
  • Undisclosed Customer – Low Pressure Turbine balance weights assessment.  (Hand Calcs)
  • Undisclosed Customer – High Pressure Compressor LCF and Fracture lifing (MARC/Mentat, Python)
  • PW1100G/PW1500G Low Pressure Turbine Redesign – 3D FEA model setup & pre-processing. (Hypermesh, NX, Abaqus)
  • PWPS Turbine Exhaust Temperature Probe – Harmonic analysis of redesigned probe (Hand Calcs)

Structures Engineer | September 2015 – December 2016

East Hartford, CT

Projects Include:

  • PW1500G High Pressure Compressor Blend Repair Limits – Rotor LCF and Fracture lifing to determine allowable blend depth and aspect ratio.  Published limits in the PW1500G Engine Manual (ANSYS/APDL, MS Excel)
  • PW1500G HPC and LPT snap diameter plasma coat repairs – Modeled snap diameter turning operation into FEA model and conducted LCF and Fracture life assessment of repaired hardware. (ANSYS/APDL)
  • PW1500G Low Shaft snap diameter plasma coat repair – Built a 3D submodel to determine the effects of a snap diameter turning operation in close proximity to a clocking hole in the low pressure shaft. (ANSYS/APDL)

Project Engineer | June 2013 – August 2015

East Hartford, CT

Projects Include:

  • Nacelle & Engine Integration Design Standard Work Overhaul – worked directly with chief engineers to document existing BOM structure practices, identify weak spots, and improve the process. (Process improvement, story-boarding)
  • FT4000 Industrial Compressor blade re-sourcing – coordinated efforts between new blade manufacturer and PW quality team to certify the supplier. (Scheduling, Punch List)
  • PW1100G Fan Hub & Fan Shaft redesign – Ran technical team meetings, kept minutes, maintained schedule. (Gantt Chart, Action Item tracking)
  • PW1500G External Bracket Redesign for Cost Savings – Worked with designers and suppliers to change bracket design from sheet metal to injection molded plastic. (Supplier interface, Preliminary Design Reviews)
  • PW4000 Fan Cowl Latch Redesign – Interfaced with supplier to move redesign through P&W BOM update workflow. (Supplier interface, Design Reviews)
