GEnx Testing

Thu Dec 07, 2006 5:30 am

Any news on the testing of the GEnx engine?

Has it been tested on the GE 747-100 flying testbed yet?

Any spotter photos?

In the Mojave Desert, at the site of the former George Air Force Base in Victorville, CA.

I believe that is incorrect.

GE leased the 747 test bed from a museum for testing their engines...funny to see a GE engine on a all pratts 747.

The GE 747 (N747GE) is alive and well at VCV. Even with a majority of Pratts.

What part do you believe to be incorrect? You certainly haven't offered anything that contradicts my statement. It most certainly does reside at Victorville.

At the time of its acquisition by GE Aircraft Engines in 1993 it was to have been on a ten year lease. It is believed to have been purchased by GEAE off lease for a nominal fee. It was utilized for testing the CFM56-7, GE90, CF34-8, CF34-10, and GP7200, among others.

FWIW, the GE flying testbed is a former Pan Am bird:

You are thinking about Pratt and Whitney. The very first 747, RA001, from the Museum of Flight in Seattle was used to flight test their first powerplant offering for the 777.

Wasn't that the one that they supposedly leased for only $1?

There's some myth/rumor/urban legend about one of those engine testbeds being leased for a buck.

It's called a Turbulence Control Structure (or TCS dome). It's made of 3" panels with thousands of holes to straighten and smooth out the incoming flow. Very useful on windy days.

Pratt did not lease it from the MoF... Boeing did. And yes, it is said that they leased it for only $1. Boeing refurbished it and used it as a testbed for the Pratt and Rolls engines on the T7.

Thanks! That makes sense.
