Bloodhound goes green eh!
That's only the case for the mono rocket, the moment it goes hybrid it's burning many kilos of HTPB (basically rubber)First it was going to be a V8 racing engine and a gearbox, (clumsy I thought) now an electric motor (better) to drive the rocket fuel pump. But I have never understood why Bloodhound wasn't designed from the outset with a pressurised tank system as used on Aussie Invader R and several other rocket-propelled vehicles. Simple construction, minimal moving parts, presumably quite cheap. Seems like a no-brainer - can anyone enlighten me?

I get the feeling that 1000mph is not really in anyones minds at the moment.
I get the impression we are unlikely to ever see that speed, on their website all reference has been removed (I believe from a cursory glance) of hitting 1,000mph and the fact it’s now got land speed record in the title which suggests they aren’t trying to push the boundary further. A shame as that’s what had me interested in the project.

The driver behind this was the safety aspect of having 1000L of HTP being maintained at around 1000psi (from memory).A decomposing HTP turbo pump would be the obvious solution, if the budget were available to develop.A readily available on board supply of HTP is already there. A 1000bhp (ish) pump would fit on a footprint the size of a piece of A3 paper

I see, thanks Marc. I hadn't considered it a serious safety issue since pressurised HTP tanks have been used in other manned vehicles and rocket jetpacks. But re your hypothesis wouldn't the initial HTP supply still need to be pressurised by some other means in order to drive the decomposing HTP-driven pump?

Yes, you'd have a small (5L or so) vessel pressurised to stary the pump, once that's done it's job the pressure is basically atmospheric inside, so you only have a pressure vessel for a short period of time & it's much smaller.Once the pump is doing it's job you bleed a very small amount of HTP pach into the pumps catalyst t sustain it's operation.
Bloodhound Diary: Planning the next steps
https://www.bbc.co.uk/news/science-environment-514...
"Now that Bloodhound is back in the UK, we are busy planning for the next step of the adventure.
With last year's hugely successful High Speed Test programme completed, we've got lots of data to work through."
Where are the companies and organisations who'd like to back a bit of British success?
How about a big display at this year's UK F1 race at Silverstone? They could even tow it around the track !! With lots of collection buckets everywhere !!

Here we go again apparently only 1 months left to save the project looks like the new owner is true to his word and will not find it to the end. So much hard work went into it to get it ready in such a short time for desert runs.

£8m is a bit chunky for crowdfunding I'd have thought, plus the best time for launching that appeal would have been while they were in SA getting wide coverage from BBC etc. rather than right now when we're all about to die from lurgy.
Agreed, the timing given the current global situation could be be worse.He stated at the time that his plan was to rescue the project and fund it long enough to perform high speed test runs. The idea was that those runs would prove the viability of the project and rekindle public interest, which could then be used to bring on big name sponsors. Those sponsors had been hard to come by before because they were't confident the project could be completed.
It seems the first half of that plan, proving viability and getting media and public interest, has been completed. The second half, using that to attract sponsors, has not worked. Looks like this could be the last straw, which makes me a little sad.

I just don't see what businesses would want to spend money to be associated with it when most marketing seems to be around how green something is. They even tried playing that card when they had social media posts about the "zero emissions" rocket they want to use. Erm... what about the whopping great jet engine underneath it?
Most people I have spoken to about Bloodhound just respond with "what's the point? if you want to go that fast get in a plane" It's a niche appeal and while the STEM stuff was great, that can be done without the car. My 5 year old son has been enjoying learning about engineering at school based around the 3 little pigs houses of all things!
It's a real shame after all the effort but the world seems to have moved on.

If Eco warriorism creeps in, all hope is lost. This is a case of ‘get a man in a car, over 1000mph, on the ground’ not really about giving a stuff how many fluffy bunnies die in the attempt. The world has changed, collective tiles have been lost, stones have been removed ( not just in the F.O.D ing sense). Having projects like this are like King Canute trying to stop the tides. Unfortunately now there are too many ‘King Canutes and not enough King Canutes left.

1,000mph is no longer on the cards hence the name change to bloodhound LSRGassing Station | General Gassing | Top of Page | What's New | My Stuff
