Thats also the reason why fighter jet engines with afterburner have a reduced BPR but with a higher fan pressure ratio than commercial A/C's. So turbo-props work fine up to ~M0.7, fans high BPR up to ~M0.95 (or little more) and above this speed a low BPR engine would be the choice,
AFAIK the Concorde was able to fly supersonic with afterburners off, once reached supersonic speed.
I was with you and agreeing Peoplesx, right up until you mentioned kilowatts and kilonewtons!
I'm afraid I'm a chain, hundredweight, fortnight man myself.
However, having seen your location, I suspect my poor attempt at humour will have passed you by without 'troubling the scorers'.
Oh dear, I've probably done it again with a cricket reference.
Seriously, I'm sure we all pretty much agree with what you say, but with reference to your words that I've highlighted, may I recommend the 'Concorde thrust from intake' thread? Not only does it have a bearing on the subject of bypass and all its aspects, it is absolutely fascinating reading - if you don't mind a bit of painless brain damage.
(Well it was brain damage for me.
