RE: Back-yard speed record attempt aims for 2,000mph

It's not clear either if he intends to use one or two X15 engines, two of them would be well over twice the rated thrust of the Bloodhound, and I'm assuming with much higher gas velocity/combustion pressure too!
If you read the article it says that he has two engines, one for the car and one as a spare. AyBee said:

Question 1.
What does a Home Built rocket car + 57,000 lbs of thrust make?
Is the answer A. 2000MPH land speed record, or B. Rather rapid end to a mans life?
Perhaps he would be happy with A + B? At least it could be on his gravestone? What does a Home Built rocket car + 57,000 lbs of thrust make?
Is the answer A. 2000MPH land speed record, or B. Rather rapid end to a mans life?
How far from the ground does a landspeed record become a rocket?
Watching the Thrust SSC video really demonstrates the ferocity of driving a vehicle at that speed - I have watched it dozens of times and I still shocked!
Given the amount of money and highly skilled professionals that went into building it, I doubt it could be replicated or beaten by anyone who couldn't match their resources.
Having said that I love a trier and shed engineering, this is the perfect combo - good luck to him!

Those landspeed.com guys have got a flippin' good idea there! Take the worlds most unsuccessful tactical fighter (Grumman Starfighter) remove wings, add wheels and presto-a-rooty! A perfectly good landspeed record car. Wow, gotta hand it to them yanks, wonder if it's got leaf springs and a live axle?
As for the other guy. Dind't he have the rocket engines left over from the Cadillac he had a run in the Mojave desert with??

I wonder how the commentary of his attempt will go?
Somthing like this maybe......
"and there he goes, increasing speed rapidly in order to enter the measure mile"
"oh, wait, he's now changed his mind, and has decided to aim for the upper atmosphere in lots of small firey pieces"
"His wife, looking on with the same dissaproving look as the day he suggested he'd this feat, is currently flicking through a copy of his life insurance policy, shaking her head mouthing "i f***ing told you so!".

I hope he his life insurance and an ejector seat!
I wouldn't want to eject from the ground (or close to it!) at any speed, let alone 2000mph!Even if you survived the initial ejection, the parachute wouldnt be able to survive the wind forces, and because you wouldnt be at high enough altitude, you'd just end up hitting the ground and bouncing half way across the united states, again in bits.
I think it's fairly safe to assume that no ejection system will be built into either the home-built car, or the Bloodhound.

This is the sort of fighting engineering spirit we had here.
Frank Whittle, Christopher Cockerell, Malcolm Campbell etc. NO computer CAD and yet they got built and worked.
Maybe he IS mad but being a 'garden shed' builder I say good luck to him.
Computer/CAD were not available for Whittle et al. Had they been, are you sure they wouldn't have used them? Did they deliberately ignore the best information/resources that were available to them in their time?Frank Whittle, Christopher Cockerell, Malcolm Campbell etc. NO computer CAD and yet they got built and worked.

I support the spirit behind the idea but assume chances of success are pretty minimal. Actual, I assume chance of him trying are pretty minimal and think this is just a way of drumming up publicity for himself.

All this information about the size of the rocket engines - my interest would be focussed on the size of the brakes and parachutes! :-)
I wonder if this potential victim of his own enthusiasm has done any stress calculations on the wheels?
He's probably done his research, and decided on some chrome 17" rims, with Kuhmo tyres.I wonder if this potential victim of his own enthusiasm has done any stress calculations on the wheels?
I hope he's got the correct offset, and that they are balanced, otherwise he might get some vibration between 1100mph and 1200mph by my calculations.
