Did i touch a nerve?
Can you sensibly answer why using pressurised oxidiser tanks is "dangerous" or really, anymore more riksy than the risks already inherent with doing 1000 mph on wheels? Pressure vessel design is not difficult, or risky, and it's used across a massive range of industries, from oil/gas to rocketry, chemical processing and many, many more (got a welder in your garage? Then you've got a high pressure vessel on that etc!
It's only used on rockets because it's the only way of getting thrust when there's no oxygen around to burn. If NASA etal didn't need to they wouldn't use liquid rockets.Can you sensibly answer why using pressurised oxidiser tanks is "dangerous" or really, anymore more riksy than the risks already inherent with doing 1000 mph on wheels?

Conversely conventional solid rockets are a pain due to being light and go with no stop. Hence the nammo one being a bit special.
The difference between rockets and most other pressure tanks is that in most cases the liquid/gas being contained generally isn't horribly corrosive. In this case the support infrastructure and getting it from one end of the track to the other would be as much of a pain as the car itself.
From memory there only been one serious rocket only lsr car and that didn't get the crown.
The reasons for not pressurising the HTP tank(or using HTP decomp to pressurise itself) have already been discussed earlier in the thread.
It's about time we pursued the USSR or its successor states for Nene royalties, China too for that matter, they built plenty of Nene rip-offs; between them something of the order of 40-50,000 unlicenced engines.

Rotate 90 degrees so it's standing on its tail.
Sell the idea to Donald as "Trump desert tower"
Or request 80 years worth of royalties on jet engine design.Rotate 90 degrees so it's standing on its tail.

No you did not touch a nerve. The reason for not using a pressurised tank has been covered previously in this thread and at some length by myself I suggest you go back and do some reading.Can you sensibly answer why using pressurised oxidiser tanks is "dangerous" or really, anymore more riksy than the risks already inherent with doing 1000 mph on wheels?

I would think that at this stage they should be sticking with whatever is simplest, cheapest and quickest to take forward. That might mean sticking with the Jaguar engine driven pump. That might be less than optimal, but if most of the problems in getting it to work have already been sorted then it may be the cheapest option - they need to be looking to save money everywhere now.

Didn't the Jag engine get dropped a while back?mcdjl said:

Didn't the Jag engine get dropped a while back?Why don't you just rip something out of a crashed tesla and stick that in? You'be got the pump already, and £10K would see you the parts (battery & motor/inverter unit) from a tesla. It's all been reverse engineered and open sourced so you can drive it directly over CAN. Peak power on typical traction eMachine is going to be around 6 to 8krpm, but with field weakening you'll be able to run a lot of power to over 10krpm.

) category but I hope it does get back on track one day to take the record & break 1000mph Alxxx said:
I've seen that there will be a programme on channel 4 about the testing last year. A last ditch attempt to drum up some funds?
I would have thought they would have been saving all the footage up for one big doc if they broke the record.
It’s never going to happen so I guess the difficulties in producing new programmes due to covid means put something together with footage you’ve got. I would have thought they would have been saving all the footage up for one big doc if they broke the record.

Pretty much, this was posted on their Facebook page a couple of days ago:I would have thought they would have been saving all the footage up for one big doc if they broke the record.
Bloodhound Is Back!
Following a seven-month period of hibernation while the pandemic caused the global uncertainty, the Bloodhound Land Speed Record project is back in business. The team has resumed the hunt for the final financial package needed to compete the development of the car, including the rocket system, and reasserted its intention to return to the Hakskeenpan desert racetrack, and set a new World Land Speed Record in excess of 800 mph.
Ian Warhurst, Bloodhound LSR CEO, enthused: “Now a global audience can see just what the car and this unique team is capable of. We’re seeking sponsors and high-net-worth individuals to help us move to the next phase and break some records!” He continued, “The project is at a stage where it either raises enough funds to carry out the record attempts, or it doesn’t, and will need to close down. There is no middle ground left. There is also a crucial timeline – the project needs to be in a position to continue by having funds in place by early 2021. This will allow the car to be developed further and completed in time for the weather window in July – September 2022. However, starting the project’s next phase will only be done once sufficient funds are held in an escrow account, and we have 100% confidence we are ready to move into the final record-breaking phase.” Read the full press release: https://www.bloodhoundlsr.com/bloodhound-lsr-prime...

I guess they’re oblivious to the current pandemic and financial implications of that. Bloodhound Is Back!
