what all the various performance times and speeds would be for the Bloodhound SSC, the same way you can do with other vehicles?

I know it's more like a plane than a car laugh , but with it ultimately being on land, would your system of performance data put into your calculator be applicable here?

If it is, because it's actually only had a bit of testing yet, is any available data going to be helpful to you?

It's worth having a look! I'll try to find some stats on it and let you know. I've no idea how a jet engine works in terms of power / 'rpms'?! How hard can it be!! laugh

Aerodynamics should be petty straightforward - if they're available...

Weight at 7.5 tonnes.

I really doubt they're be interested in pushing it 100% while accelerating. More likely it will accelerate faster and faster as the speeds rise as the aero kicks in.

All that said though, I should think the primary limiting factors will be keeping it stable and how much the driver wants to go home after work...


F****** b****** thing...

I think that might bring you back to the discussion you had a couple of weeks ago about the weight effect of negative lift.

Bloodhound has - of necessity - shedloads of negative lift to keep the damn thing on the ground. As to how much, and what it does when it goes supersonic... enjoy the calculation.

Since it doesn't drive the wheels, and the jet's going to be pretty much flat out, it should be a straight-forward F=ma calculation for acceleration.
