V94 Program Manager Gas Turbine Parts Services

Seth Thomen | V94 Project ManagerBackground

I started as a Manufacturing Engineer at Pratt & Whitney® 21 years ago. I have worked with nearly all components of Military, Commercial, and Industrial Gas Turbines (IGT).  I started re-engineering aero components 15 years ago and have been re-engineering and bringing parts to market for the last 10 years.

 What do you do here at MD&A?

Here at MD&A, I manage the development and production of aftermarket replacement alternatives for Siemens® V94 turbine components.

What is the most interesting challenge you have come across on a V94 component?

A continuing challenge when re-engineering a V94 or any component is to not duplicate a manufacturing error.  It takes a solid knowledge of both design and manufacturing turbine components to be able to distinguish between an intentional geometry, or simply a drift in manufacturing from the origin design intent.

How does MD&A work with the customer on component repair process?

Our team utilizes a multi-stage gate process, which provides the client with an important checkpoint to review the project’s progress with our engineers. This partnership eliminates guesswork, enhances quality, and reduces repair times.  Upon component repair completion, a final report is compiled & transmitted to the client.

How can our unique coatings meet the unique challenges of gas turbine environments?

The ceramic Thermal Barrier Coating (TBC) applied on our repair and new parts by our San Antonio Service Center is one of the cornerstones of our success.  Our coating is based on and further developed from the coating applied at our shop when it was a Pratt and Whitney® Military and Aerospace repair facility.  With our coatings we support 33K EOH interval aftermarket components, effectively allowing us to extend the life of the part.

What is your personal motto?

A Good Education Is Not Cheap, Or Easy
