Their Fj Series engines are pretty close in design to the TF-34 engines.
They also do allot of small jet engines for Cruise and UAVS.
I reccomend getting into a Company like this. They build, Test-Cell and ship. All the Components are manufactured in house at the same facilities. From here you could climb into the The top 3 PW, GE, RR.
Reaserch is at Walled Lake Michigan and the Production and Build is at Ogden, Utah (close to the HAFB depot)
I spent a winter as a Contract Engineer on the Tactical Tomahawk Program. Being an Aeronautical Design Thermal Dynamics Engineer. Having this exposure to Propulsion design manufacturer was a Good Career builder. I even had the opportunity to build engines step by step and test cell.
Most Aerospace jobs are very narrow, and you dont get to see the full spectrum of the product under one roof.
If you want to grow a career i recommend getting into a company like this.
You may find that you may want to become a Machinest, Engineer, Materials QA, inspector, Planner etc. Or continue on doing the Jet Mech.
Most Jet mech jobs are service center buis jet stuff. the Airline require Very heavy College and FAA Certs. Which make them tough to get into straight out of the service.
With Williams and others they grow you from apprentice up to full prficiency. With your real world experiance it makes this transition easier and solid investment into your future.
