It yields the strongest products and company.

CAREER SUMMARY

Pratt and Whitney @ Amercon, div of United Technologies Corp/

Rolls-Royce thru CDI Engineering Solutions/

Allison Advanced Development Comp./

Allison Engine Company/Detroit Diesel Allison/

PRATT & WHITNEY – AMERCON PLANT

P&W, headquartered in East Hartford, CT, had revenue of $14.5 billion, and 31,500 employees supporting their gas turbine manufacture as of 2013.

At Amercon Plant (TURBINE BLADE & VANE FABRICATION) ‘evaluate hardware for Material Review Engineer.’

Assess deviated parts & recommend accept, salvage, or scrap. Includes hardware for the JSF (Joint Strike Fighter), NGPF/GTF (Next Generation Product Family/Geared Turbo Fan), FT4000, PW4000, V2500, JT8D, JT9D, GMS-CFM56, PW2000, F100, & J52 product lines.

Personally answer over 3100 QN’s (Quality Notices) taking a full MRB crib backlog to ‘0’. This while production added more parts for the NGPF/GTF & JSF ramp ups.

Became skilled in using SAP to process Quality Notices and consult part deviation history. Also personally created part files for the blades and vanes in the product lines. This in attempt to match the decades of experience my blade mentor and my vane mentor have with Pratt and Whitney parts in the East Hartford home office. (‘12MR-‘15MR)

ROLLS-ROYCE THRU CDI ENGINEERING SOLUTIONS/

ALLISON ADVANCED DEVELOPMENT COMP

Indianapolis, IN Operations was a $500+ million, 7,700 employee maker of gas turbine engines as of 1993.

Product Improvement Engineer- dispositioned $5+ mil of hardware (‘08FB-‘09JN).

Combustor Engineer -501K Ground Power Units and T56Aircraft (‘06SP-‘07SP).

o-501K Combustion Liner make alterations to reduce field hardware cracking and support through Product Change Board process (‘07Fb-‘07SP).

o-501K Overhaul Manual review and make input to Combustion Liner processes (‘07MR-‘07SP).

o-T56 Series III Analytical Condition Inspection-create forms to assess the Combustor (‘07MR-‘07SP).

F-136 Engineer for Alternate Engine Combustor working Unigraphics Team Center (‘05AG-‘06SP):

Project Engineer wrote Statements of Work and ran programs CDI did for Rolls-Royce (‘04DC-‘05AG).

RESA (Request for Engineering Source Approval) Engineer changing EDS 1306 Fixed Processes on production engines for improvement and cost reduction (‘04MR-‘04OC).

Turbine Engineer- Controlled GA (General Arrangement) of an ATEGG (Advanced Turbine Engine Gas Generator) using Unigraphics CAD. GA showed current geometry and coordinated interfaces between partner companies. It included bounding/incorporating parts from individual designers into the GA. To improve program clarity, notes were added to the GA showing part name, designer, and material. Also added were drawings showing assembly steps. After preparing an export version, the GA was used in carcass stress analysis (set boundary conditions for detail analysis). A stack spreadsheet was created that includes shimming and uses dimensions from the GA to calculate hot, cold, and thermal transient gaps/laps using internal alpha tables and analysts’ temperatures (‘00FB-‘03DC).

-Designed and coordinated manufacture of temperature resistant (niobium silicide) airfoil ‘jacket/tiles’. Optimized program $’s by designing 1 tile to fit multiple sites on airfoil. Design included attachment to an existing airfoil and contouring cooling geometry. Offsite manufacture of tile was accomplished using electronic file transfer. (‘00FB-‘01FB).

-Support for AE3007 magnesium Front Frame & aluminum Air Inlet Housings (‘99MY-‘00MR).

oInvolved with application of corrosion/erosion prevention coatings to engine parts processed in/out of house. Revised HAE Coating spec EPS11820-J and integrated with production. Included documenting salt spray corrosion test results and interface with materials people.

oAlso involved in manufacturing regarding thread inserts.

oDirect layout investigating possible alternate oil sump arrangements (‘99JN).

-Designed test stand mount for JSF core using UG and interfacing with personnel from Test, Stress Analysis, Project, and the teaming company (‘99MR-‘99AP).

-Work on JSF Splitter and Instrumented Splitter (‘99JA-‘99FB).

-Held design creep deflection of JSF Lockheed Martin 3rd stage blade shroud wing tips below 0.005” as specified. This was accomplished by creation of a spreadsheet that allowed assessment/improvement of shroud design and showed resulting shroud weight (‘97AG-‘98OC).

-Did preliminary design of the JSF 3rd stage airfoil using a unique lightweight shroud, setting blade wall thickness to meet rupture requirements, and running programs to define the attachment (‘97AG-‘98OC).

-As Turbine Design Engineer, in AADC, provided hardware design and test stand support of an engine core (GX801) test demonstrating a 200F RIT increase with transpiration-cooled airfoils (‘95JA-‘97JL).

United Medical Manufacturing (‘94JA-‘94NV follows)

Inlet Engineer -Coordinated analysis, 3D CAD efforts, and interfaced with vendors involved in the development of components for the Inlet Particle Separator System (IPS) for the T800 US Army helicopter engine including blower, anti-ice air control, ducting, and IPS casting parts (‘93MY-‘93DC).

Conceived a geometry that more effectively used anti-ice air and raised an ice prone surface temperature 10 F, analytically avoiding ice formation on the T800 IPS (‘93MY-‘93DC).

Miller Pipeline Corp (‘89FB-‘93MR follows)

Project Engineer for Metal Matrix Composites Technology and I R & D programs for the development of ultrahigh strength materials for gas turbine compressors (‘87Ag-‘89Ja).

Design Engineer worked 250 series production and development aircraft engines (‘84JA-‘87AG):

oFixed combustion case cracks on Model C30 via braze attached screen patch technology. This preserved expensive company tooling, saved customer $’s by allowing field rework, & maintained FAA approval.

oGreatly reduced customer annoying cyclic noise by designing a squeeze film in the C30 turbine bearing.

oReduced oil coke and sump temperature 10 F on the C34 engine by using a secondary radiation shield.

oImproved primary heat shield life with a ceramic spray thermal barrier on the C34 engine.
