They called in an unducted fan or ultra-high bypass turbofan.

So much for memory g Right idea, wrong end of the engine.

We put ours on the spine of the Jetstar and drove it with bleed air.

That DC-9 you recall probably belonged to GE, which has a test
facility in Mojave.

GE red hats from North Base did the UDF and the GE90. IIRC there is only an
artist's rendering of the UDF on an MD-80, while the engine actually flew on
the flight test 727-100 that lives at Mojave.

I'ld guess you'd end up with an all weather plane between a P-38
and P-61 in size. Likely twin turbo prop to free up the center
line for radar and the gun.

A couple of alternatives for the centerline gun

- Through the prop hub as per WWII engine mounted guns (wasn't the original
idea for a 20mm Birket/hispano like this from WWI?).

- Rear engine as per some studies for CAS in the 80s, BA?

Or both as per Dornier 335, hmmm 2 x Bear engines (15,000hp each) might be a
bit much.

I imagine it might be a bit large too :-)

Just how long would the main gear have to be?

You're right. I was thinking, as I wrote "DC-9", that something
wasn't right about that, but I couldn't quite remember what. It was a
727, not a DC-9, is what.

Photos of it, with the odd engine, would show up now and then as a
"look at that" item in the various aviation magazines. There was at
least one in "Straight and Level".

In '97 when i was contracting at Boeing Everett there was a manager with the
MD-80 artist's rendition on the wall and i mentioned that the engine had at
least flown on a 727.

The funny part is that the flying MD-80 artist's rendition is used fairly
commonly to show the engine, even though it never happened.

The UDF on an MD-80 flew. They even took it to Farnborough in 1988.

That's really cute, but not the one in the picture we are discussing.

How about this ugly thing mounted on what appears to be the wing of a DC-9
(upper right image in the group of three).

It's not as pretty as the one in the picture in question. Although the DC-9
would have provided a much more likely vehicle for production. The UDF was
tested back when Pratt was sucking gas, but things have changed since then.
