Brian,
And of course that has nothing at all to be doing with Peter Kent's question
That was really aimed at my response to Bill Lyman's questions not the original question.
I assumed he (Peter) was talking about Mach 3 conditions, but the subsonic conditions are of course as you describe them.
Since posting that contribution on ejector nozzles I have found another useful source which gives a good explanation of how they work:
NASA TM X- 67976
FACTORS WHICH INFLUENCE THE ANALYSIS AND DESIGN OF EJECTOR NOZZLES

I have to disappoint your expectations I'm afraid - I will own up to sort of understanding intakes and a working knowledge of nozzles, but what goes on in the guts of the engine is a mystery to me - a bit like the dark arts of the rugby front rows
For that sort of discussion you need real experts and I would, like gums, dearly like to have Dr Abernethy in on it!
I can confirm M2dudes story of Ted's US visit however - I got it from the horse's mouth. A bit off thread perhaps, but I thought folks might like to see the evidence ....
