Barit-1

A variable-cycle turbo-ramjet, did you say, with possible TSTO capability? Then you're just the person to answer my next trivial question.

Given that aside from propelling the aircraft,...

Right on, Barit!

You make a very good point here. But it still seems to make more sense to have the "fan" stages feed a classic circumfirential duct, allowing both the harnessing of that airflow for "propeller"...

ALL

Am still curious as to the actual efficacy of those six "tubes" and wondering if they collectively had the air delivery capacity of an "honest" classic bypass duct (eg. F-100/101/110/RM-8/M-53,...

Iampaseo

The point I was trying to make, in my clumsy way, was that if only for some semblance of corporate continuity, designations have tended to be contiguous, with "JT", i.e. "jet turbine" being the same...

Thanks Jane, good work

Great info there, and now recall that the first two stages of the, by then defunct, J-91 became the fan for the turbofan version of the J-57/JT-3, i.e. the TF-33/JT-3D. Since the inlet diameter of...
