Hello CliveL
But I don't understand what you mean when you talk about 'bleed drag' What bleed? What sort of drag? How do you think reducing 'drag' (an external force) could 'unleash power from the Bypass' (whatever that might mean)
I did not mention "bleed drag". My comment was based on Dr. Bob's PATENT, in which he fully describes the purpose of his bleed pipes, and his offer of a TurboRamjet solution: which he discards, as "too heavy".
Part of his claims, specifically, was to offer his bleed system as having a twofold cooling effect. First, reducing Temperature at the vicinity of bleed "entry", and secondly, upon re-introduction to the ejector, cooling the AB "LINER".
I DID infer that relative to his claim of partial RAMJET gains, he was linking this increase of thrust to a prior DECREASE in choke pressure.
What I think is a logical inference from that is that he is relocating what can be thought of as RAM EFFECT, (choke), from the compressor to the EJECTOR, via this bleed scheme.
That is all.
