Although generally ignorant about aircraft, I have been absolutely rivetted by this thread, and can only sit in awe at the complexity and perfection that has been revealed here.
I've pretty much managed to keep up with the principals and technicalities involved, but there is one thing I don't understand. Could you explain to a complete novice the relationship between IAS, TAS ,GS and Mach no.? Apologies if this is obvious to most here, but you can't get away with writing such a brilliant account of such a wonderful aircraft without attracting the odd ignorant byestander!

Thankyou guys for your lucid explanations. Things are now a great deal clearer, and I now understand how you can be doing 550 knots at Mach 2, which previously seemed impossible!
Now, more about that beautiful machine, please... Subjects: None |

This just goes on getting better. Welcome Clive!
After all the high tech stuff I have a much more prosaic question. Looking out of my Devon window this morning I could see aircraft streaming up the channel, and by checking their positions on Flightradar 24 (sad, I know) I know that I can see craft at fl350+ nearly the whole way across the channel, so it occurs to me that I should have been able to see AF Concordes on their way into CDG, but never did (although I certainly heard them). Would Concorde have been visible from the ground at cruising height, and would it have left contrails?

I saw her only once, around '73 - '75 (?) when she did a low-level tour around the UK. I was driving down a Devon lane in an open car when she went over at around 3000' completely unexpectedly. In Devon, you see a few helis and the odd military jet. The rest is just contrails with dots on the front. I shall never, ever, forget it.

It seems to have gone a bit quiet on here, so here's another question from an ignorant bystander. Having just got hold of the ITVV DVD, I noticed reference during the FE's walk-round to areas of unpainted aluminium below the front door referred to as Static Ports. What are these?

That brings a question to mind. Under service conditions, how long would it have taken to remove and replace an engine, and how often would it have been done? Also, would the same engines have stayed with each airframe, or would they have "circulated" around the fleet?

Down here in Devon, the only contact we had with Concorde was the spine-tingling "whomp-bomp" every evening as flights out of CDG lit up down the channel. Replaying that sound in my memory, I would say that the time between the two thumps was between 1/3 and 1/2 sec, and yet a bit of maths tells me that at 1300 MPH, Concorde travelled her own length in less than 1/10 sec. This always puzzled me at the time, and I still can't explain it. Any ideas, anyone?

.25 seconds for Concorde sound about right.

Someone's done the same sort of thing, albeit on a smaller scale, for the Bugatti Type 35. Is this the sort of thing you're contemplating?

If you succeed, it will be the most fantastic resource, but I don't envy you the task. The Bugatti took 4000 hours to complete and has around 3000 components. Anyone care to hazard a guess at how many components Concorde contained?

One would hope not! I suppose you just have to make a decision about what sort of level of detail to co to. Brilliant idea though, if it's feasible.

Not crazy at all. If it's in any way feasible, it's a brilliant project. Best of luck, and keep us posted!

Several times I've seen mention of the cockpit crown mods. What were these, and what was the reason for them? Were they applied to all the airframes?

Main gear stresses
I just watched a video of Concorde turning onto a runway prior to takeoff. The turn was sufficiently sharp for the aircraft to be virtually rotating around the main gear. This is the equivalent of a vehicle the size of a small truck being dragged around in a circle whilst at the same time carrying a load of around 90 tonnes. Howcome it didn't screw the main gear straight out of the wing?

I have a query about the thrust of Concorde's engines. The quoted static thrust of the Olympus 593 is 32,000lb, but it has been frequently stated that in supercruise, the majority of the thrust was provided by the intakes. That being so, how much thrust was actually produced overall at Mach 2, and how was this measured (if indeed it ever was)?
