Hi to All….and thanks so much for your help!
@POPS….I know very well the words of Enzo Ferrari…but I think that aero the work of Colin Chapman is good too! 😉
@Malcom UK.
Malcom…very interesting points. First of all thank you. I will try to give an explanation to your request!
“Is it to be a dream vehicle, or should it be feasible to build it quickly, because the timeline for someone with a current car getting to the target speed might occur within five years or so.”
→ The complexity and ambition of the project make it a “dream vehicle”, but this thread aims to define a Concept with a concrete feasibility….maybe with a 5 or 10+ years of work (es: treit & davemport, carbinite or bloodhound…) …but with what technology allows us.
“Track - what length of asphalt or concrete is available - straight and level. Do we know if it could have traction compound spread along the full acceleration distance? Is it located at altitude or sea level. Where is this track?”
→My idea is to run in track that are used for standing mile: Texas mile, Mojave, ohio mile…I have said that the ½ run could be a distance that in the same time could permit the acceleration to 500mph, a good shut down area, and the engine stay full throttle only fiew seconds. But it is just indicative (sorry…I don’t know if it is correct in English language)…the correct length request for the run could be a little higher or even shorter!
“Power unit(s) - although not being a 'lover' of all things electric should this be the power unit(s) of choice? “
→I am not a lover of electric powertrain too
…but the goal is to hit 500mph…all wheeldriven powertrain could be used. ( i give you a link:
https://insideevs.com/electric-dragster-boasts-1000-volts-5000-hp-17000-pound-feet-of-torque/ - In fact, There is an Australian team that is building a sort of EV-top fuel that could hit 387mph or mach 0.5)
“Acceleration - Can a push truck be used, or is the intention to drive away from rest? Do we need the drag racing g-force launch effort for the chosen length of track?”
→We are not make a NHRA run…there are no FIA/SCTA/NHRA regulations …everything is permitted.
“Tires - must be good for 500 without failing/bursting. (This could be from rotational speed effects or surface stresses caused by spinning up). A tyre maker may need to be part of the 'design' team?”…
→OF COURSE!...I have written in my posts that if a tyre maker could be a part of the team should be fantastic…..without a tyre maker able to develop a specific tyre for this performance, the only idea that I have, is to coupled mickey Thompson tyre…….
“Traction - is it conceivable that a drag racing rear tyre might be constructed to give the required traction over the full acceleration phase (and the distance that involves)? If drive is required to four or more of the wheels/tyres, then the body design will need to take that into account. Enhanced downforce, say from stationary (at rest), would require a dynamic 'fan' system or similar but will this need to be controlled throughout every part of the acceleration phase. The drive motor then needs to be controllable, but perhaps not by the driver”
→I think that the correct calibration/control of active aero or Fan devices is one of the most difficult parts of this kind of project….I agree that the drive motor could not necessary controllable by the driver.
“Measurement of speed - I take it that the rules that those on this list abide-by for timing are to be thrown away and an on board speed GPS measurement system will be used. No fixed position timing beams of any distance interval to be used”
→Ok!
I hope that I help you to clarify my intent….Sorry for my bad English.
I am available for every question!
Thank you
