Introduced innovative, integrated cast FINS/inducer design enabling key turbine cooling technology on engine as well as reducing cost and part count. Successfully presented conceptual design review and long lead material release review to senior engineering team.
As a Material Review Board (MRB) engineer, assessed and provided dispositions on thousands of manufacturing non-conformances on both cold and hot section engine structure hardware for commercial and military programs including the GE90, GP7200, F101 and F110 engines. Worked closely with suppliers and engineering team to identify repairs or rework in cases where parts were not acceptable as is, avoiding hundreds of thousands of dollars in potential losses.
Provided time-critical engineering guidance to Product Support Engineer for GE90, GP7200, F101 and F110 engine hardware. Reviewed engine manuals, existing analyses and new-make non-conformance and repair history and performed engineering assessment to disposition hardware, including initiating specific analysis if needed. Engaged Materials Application Engineer and consulting or principal engineers in review of field return hardware to investigate root causes of failures. Identified need for design fixes/improvements to address failures or distress observed in field.
Introduced material changes on two GP7200 CDN structures components achieving $1500 per engine cost savings. Released optimized fan frame castings to production, resulting in 30 pound weight savings and 15 hour reduction in manufacturing cycle time. Engaged sub-component supplier to improve durability of part, and advocated direct sourcing strategy with management to reduce cost of parts.
Introduced durability improvements and assessed new repair procedures for various parts and components of the GE90-94B and -115B engine CDN, HPT, and turbine center frame (TCF) to extend part lives, reduce field support cost, or meet commitments to customers.
Authored numerous design changes to improve producibility and reduce manufacturing cost with a total impact on the business in excess of $1M savings & avoidances.
