Structural Engineer

• Nov 2017 - May 2020

As structural calculation engineer I used to work on both the development and the entry in service of the A330neo exhaust, and I now work on the development of C919 exhaust.I daily deal with the following tasks:- To ensure structural calculation using both numerical (FEM: Patran/Nastran - Crack growth: NASGRO) and hand calculation methods: static, fatigue, damage tolerance...- To perform structural analyses in order to cover reported nonconformities in production, engineering… As structural calculation engineer I used to work on both the development and the entry in service of the A330neo exhaust, and I now work on the development of C919 exhaust.I daily deal with the following tasks:- To ensure structural calculation using both numerical (FEM: Patran/Nastran - Crack growth: NASGRO) and hand calculation methods: static, fatigue, damage tolerance...- To perform structural analyses in order to cover reported nonconformities in production, engineering change requests, or incidents in service,- To take part of a new product development including cross-cutting discussions (structural, thermal, material, design...),- To write calculation/substantiation reports, FEM reports, and structural certification reports (based on both customer and CS25 requirements),- To participate in the validation of technical reports as being 'technical reviewer',- To coordinate calculation activities with subcontractors and to manage stress issues with the customer.

Final-year internship as Structural Engineer

• Mar 2017 - Sep 2017

Objective: To implement and study coupled thermomechanical finite element models related to exhausts' nozzle for both in service (A380) or under development (A330neo) programs. Issue: The trailing edge of exhausts' primary nozzle sees both cold and hot flows. The resulting thermal gradient is the main source of stresses in this area (differential thermal expansion). A detailed analysis of this area is then necessary to get relevant results.- To implement the thermal finite… Objective: To implement and study coupled thermomechanical finite element models related to exhausts' nozzle for both in service (A380) or under development (A330neo) programs.

A detailed analysis of this area is then necessary to get relevant results.- To implement the thermal finite element model in order to get the inputs for the mechanical model, and then to implement the coupling (using one common model),- To perform a comparative study in terms of solutions of contact available in Patran-Nastran,- To realize influence studies in terms of: materials, geometry, mesh, loads...- To investigate hand calculation possibilities as pre-sizing tool for this exhaust system part.- To improve the information exchange efficiency between Thermal and Stress departments.

Internship as Engineering Assistant

• May 2016 - Aug 2016

Objective: To design a new drilling procedure in order to improve the tool life and the holes’ quality, optimizing drilling parameters (geometry of the tool, cooling system, chatter conditions management) and simplifying the process.Issue: Titanium is a hard-to-machine material which requires choosing the appropriate drill bit and drilling conditions to obtain good quality holes (without tool mark, without ovalization...).Project Partners: CTRM Aero Composites, SDMK and AMIC… Objective: To design a new drilling procedure in order to improve the tool life and the holes’ quality, optimizing drilling parameters (geometry of the tool, cooling system, chatter conditions management) and simplifying the process.Issue: Titanium is a hard-to-machine material which requires choosing the appropriate drill bit and drilling conditions to obtain good quality holes (without tool mark, without ovalization...).Project Partners: CTRM Aero Composites, SDMK and AMIC. This project was linked to the nacelle program "A350 XWB Fan Cowl". - To write a literature review regarding titanium drilling,- To find new technical solution in order to reduce chatter conditions and heating,- To design some parts on CATIA V5 (drill bits, drilling guide, cooling system),- To implement a dynamic finite element model on ABAQUS in order to optimize the geometry of the drill bit, the material to use and some drilling parameters.- To write reports and to perform oral presentations.

Industrial Placement at Badoit, a subsidiary of Danone Waters

• Feb 2015 - Feb 2015

For a month, I worked on the production line as a factory worker.- To supervised the production, - To perform quality control procedures, - To make sure the supply chain was correctly working, - To clean up my work space (conveyors, production machines). I worked in a team, with two eight-hour shifts.
