P&W JTF17 (Proposed Boeing 2707 SST Engine)

[shockonlip]

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

http://www.secretprojects.co.uk/forum/index.php/topic,1848.msg119827.html#msg119827

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).

DTIC seems to have many new(?) JTF17 documents uploaded, like these jewels

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.

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

Very interesting Boeing report comparing the GE4 and the JTF17:
