Since we can't unlock propulsion posts from aircraft prior aircraft
discussions, let me point at some in this new forum.

Above link discusses P&W JTF17 SST Duct Burning Turbofan.

The JTF17 became the foundation for future composite engine cycle work done later
by P&W, as the GE4 did for GE (I will post more later).

Once upon a time, many a year ago, there was an aviation museum near Kissimee, FL that had the Boeing SST mockup. It also had a JTF17 engine. I don't know what happened to the museum or the engine but 'twas fascinating to study the engine.

As Flateric noted earlier, DTIC has a wealth of information on both engines. I have scanned a few of the reports, and I found it interesting that, among other things, the GE4 had better transonic acceleration, a larger window for growth in static thrust (43% IIRC), and produced less noise, than the JTF17.

I'm surprised it's maximum g-limits are so low: I'm guessing some inlet guide vanes would fix that?

No sweat -- found while looking for something else, naturally.

DTIC is the go-to site for SST engine info.
