What condition is it in? Unless they've done something more than just shove it into a corner and throw a dust sheet over it, then it's probably just scrap.

It's been inhibited & is in Coventry Transport museum,

False.

What is required is either an oligarch willing to spluff serious money on this as a hobby, or something along the lines of Drive to Survive level of turnaround in interest by a new demographic, such as happened with young people/netflix/F1 recently.

Exactly - needs three things;
1. Someone with serious money,
2. Someone with serious fame to get properly involved (of any sort, but high-profile for a lot of demographics),
3. A TV production company and a service willing to take on the challenge of showing / "making up" the excitement of the endeavour.

1 & 2 could be combined, of course, but without 3 it is pretty much doomed to mediocrity - sadly IMHO, but no less true for my sadness.

3 is relatively easy 1&2 are near on impossible, they haven’t found that sort of individual in the years they’ve been trying to seek funding, the longer time passes the less desirable the project is the less likely it is to attract someone with an appetite for risk.

They should flog it to Rosco McGlashan in Australia for cheap and let him have a go at getting it moving. Although maybe the restriction what they are allowed to do with the EJ200 might stop it from being run by a non-UK concern.

I reckon he'd rather just have the ££ to finish his own one.

What do you guys think of his design - propulsion & aerodynamics? Is it viable?

He's 72. Can't see the car being ready and him being fit at the same time.

As for the car, it needs to cope with a supersonic shock wave travelling under it, so the wheels will be travelling on liquefied ground. It's nontrivial, which is why the bloodhound and thrustssc cars had so much simulation (including physical models on rails at real speeds). Rosco has had involvement from academia in his cfd version of this but I question it.

Tl;dr it's not been done like bloodhound, I'd not trust it.

[blueST]

It does look a lot like Blue Flame and the Budweiser Rocket which are more than a few years old.

[Arnold Cunningham]

I don't get how the fuel & oxidiser delivery works on Rosco's design. It seems the pistons that travel up the cylinders would only need a minor snag to get the ratio off beat?

In control theory terms, that bit looks very open loop, so while it can be monitored, I can't work out how the mixture ratio can be controlled. Or do rockets not require much finesse on the oxidiser & fuel ratio, so as long as it's grossly OK, it'll run?

I agree re. modelling. Feels like you'd want to get it to the "running quite well stage" to attract funding to properly then simulate the supersonic hurdle.
It's decent enough that he's done some CFD, but at least there'd need to be quite a bit of testing to validate the CFD models = reality.

Which is why I like Rosco's design, the round form seems a practical "easy" way to minimise shock waves (compared to the complexity of the modelling required for Thurst SSC and Bloodhound).

Plus a lot of weight included to temper the acceleration to manageable levels.

He's a vastly experienced driver, probably more so even than Breedlove who might have taken the record for a while in 1997 bar some slapdash running procedures.

I don't follow his rocket design either, seems both projects could have done with the long promised off the shelf rockets e.g. Nammo.

Has anyone tried getting Elon Musk onboard with it? Potentially useful link up with Space X and Tesla tech.

They have spoken to him but his interests are only in space travel, not land speed records.

He only owns a car company to finance his space exploration.

Hard to get excited about mach 1 on the deck when you're doing mach 18 routinely.

Don't agree with this at all actually. I think he would have killed himself if he'd gone for Mach 1.
Fortunately some slapdash running procedures and a bit of luck kept him intact.

Also I get the impression that he's quite hands-on with all his projects, and likes to know about it all in great detail. Taking on an almost-finished project of this size isn't the sort of thing he'd have the time, even if he was interested. It's probably going to be the same for any wealthy investor.

I imagine the other issue is that everybody has moved onto other things, and presumably only a fraction will be able to return to it after all this time, so there will be quite a lot of work to recruit the missing skillsets.

[Evanivitch]

There's been an update. Project very much being kept alive. Plans to use net zero fuels.

Given the EJ200 comes with the gift of support from Rolls Royce and the RAF, I don't think it's likely to travel abroad for another company to take control.

I wonder - would it need totally re-designing in order to use a (HTP) rocket as the main propulsion system? I would guess so, but it would open up various options for "green-ness", tie-in with the existing rocket makers etc.

Strictly speaking Mach 1 wasn’t the record, when he started running the car 640mph would have taken the record and he crashed at about 675. It was a year later when SSC put it out of reach.

[Alfa numeric]

There was an article in Car Magazine a couple of years after the record was broken about the two attempts- apparently the Thrust SSC team really wanted Breedlove to break the record before their attempt as they knew they knew it would be out of his reach afterwards. I think some of them even worked with Breedlove’s team in their down time.

Out of interest, how is HTP manufactured in a green process? I know the exhaust gases are clean, but I had zero idea how hydrogen peroxide is made so I googled it... The industrial process I found (which presumably came about during the days when children were encouraged to use asbestos as snuff and to chew on uranium) involves a coal tar derivative and hexavalent chrome

IIRC the main process for producing hydrogen peroxide these days is the Anthraquinone Process which itself is pretty clean. One of the processes for producing the precursor Anthraquinone is what you describe here I think (Anthracene oxidation with a hexavalent chromium catalyst), but it's far from the only way it's produced.
