Hi peter

Abernethy claims a twenty percent plus increase in thrust from the bleeds scheme. This augmentation is not only purposeful, but the system, by his desription, allows the engine to travel at 3M when it was essentially paying out at 1.7. So the engine, functionally, has two separate modes.

His lead in to the description of the challenge claims the problem was ram air, causing high temperatures and choking (blocking) of the inlet area. Now ram air is without doubt a precursor to a Ram System of propulsion, and the problems he describes present a possibility of utilizing this "problem" to accomplish ignition and sustenance for a true RamJet.

He also describes a Turbo Ramjet solution to the problem. For this, he proposes a true bypass around the core, not just bleeds, but dismisses the possibility as heavy and not workable.

I wonder if he was dismissive too early?

Are you aware of any work done to pursue this?

Your post above is compelling. When is a cucumber a pickle? At what point does Abernethy's "PARTIAL RAMJET" become a true RJ engine?
