Thanks
Wow what a fascinating thread to have stumbled across .
Its so great to have a discussion which is full of facts from people who were there and know the truth rather than all the usual half baked opinions and theories.
On which there was a splendid rumour that what put the final nail in the great birds coffin was that our transatlantic allies realised that if hijacked there was nothing that could catch her !!
Rod just a ppl

Nitpicking
A detail I know but wasnt the Olympus really a Bristol engine? (cf Hooker "not much of an engineer" )I know RR bought the company but it wasnt their original design

Thank you M2Dude for all this priceless info
I agree about Stan Hookers book and before he died he also recorded remeniscences on I think, a BBC program, I have it somewhere on a tape, must find it and transfer to a dvd
Ps the rumour was tongue in cheek

Engines
My physics has pretty much rusted away so can anyone help me with this, The frequent statement that the intakes accounted for approx 80% of the engine power when supersonic. I quite understand that the intake air has to be slowed to subsonic before it meets the first compressor disk but saying that the intake produces 80% of the power almost implies that you could turn off the fires and still have 80% power. Obviously that cant be right! and another thing I dont understand is how shock waves slow down the intake flow, so any help with that would be useful to me. Any aerodymicist/physicists out there?
Thanks and keep up the super remeniscences

If your talking about real profit, does anyone know what the true development costs were and how many airframes they would have had to sell to break even.
With the governments (or you and I really) paying all the up front costs the suggestion that concorde was ever profitable is a bit of a myth . Technical tour de force that it was.

With all due respect Cristiaan Im not mistaking operating costs and development costs.
If I as a company develop and sell a product then its not profitable until all the development costs have been recovered. Operating costs are a matter for the buyer, not the manufacturer.
I know the costs were covered by the governments and that was what I was really asking, what was the break even quantity for the manufacturers.
Obviously the benefits to the existance and technological advance of Airbus is a seperate and unquantifyable matter

Yes Its all a terrible terrible waste.
So you have to ask why nobody foresaw the problems of supersonic flight over populated areas, If it hadnt been for that maybe concorde would have been a commercial success as distinct from a technological one.

Hi Landroger
But for those of us who were brought up as engineers in an analog world its not so scary.
remember by the late 60s chopper stabilised amps were well established and drift was much better controlled,
Is it an analog world out there? I think so

Channel 4 video
Just managed to locate and download a copy of the Channel 4 program "Last flight of Concorde"
Well worth watching if you havent already seen it with lots of good archive footage.
Just one question for our resident experts, why were the Olympus 593 s so smoky to start with, did they use excess fuel to help with cooling as some petrol engines do or was there some design feature which caused the smoke. It seeems to have been cured in later engines

M2 Dude
I think TSR2 is probably my favorite ever, I once got a job interview at Cranfield not long after it was cancelled just so that I could go and look at it in their museum.
I remember being amazed at how large it was
cheers
