The highs and lows of land speed racing |

- It’s 04:30 and the sun is just peeking over the horizon in the Kalahari Desert, turning the sky vivid pinks, blues and yellows. It’s a run day and the Bloodhound Land Speed Record Team are preparing the car for a high speed test run: 350mph.
I’m the communications manager for the UK based team who designed and built the ultimate straight-line racing car. A team of 30 of us are here on the Hakskeenpan, in the Northern Cape, South Africa to put the jet powered car through its paces during a rigorous high speed test programme.
We’ve already seen the Eurofighter Typhoon jet powered car reach 501mph during the test programme, but today we’re aiming to test the air brake doors at around 350mph. The air brake doors are like huge carbon fibre elephant ears that stick out either side of the car; these generate drag (like sticking your hand out of the window of a moving vehicle) to bring Bloodhound LSR car to a safe halt.
Following a team briefing the car was towed out onto the Pan, a huge dried out lakebed 12 miles long and two miles across. Once positioned on the white line the Start Team set about plugging in the Air Start Cart (a small gas turbine used to start the car’s jet engine). The Air Start Cart cranked up and started blowing high pressure air but the jet engine refused to ignite.
It’s heartbreaking when, after many hours of meticulous planning and resolving some challenging issues over the last week, the run was cancelled and we had to return to Tech Camp to plug in the Systems Engineers and review the data. Crestfallen the team trudged back to their vehicles and we returned to base.
After several hours the source of the issue was identified (the DECU - Digital Engine Control Unit - failed to send a Start Request to the jet engine) and a software fix resolved it.
It’s now midday and temperatures are reaching the mid 30’s, so it’s a quick lunch and back out to the desert with the aim of making the two planned runs.
Under the searing heat the car was lined up on the line and plugged into the Start Cart. To everyone’s relief she fired up first time. A quick radio check with the Run Controller “Bloodhound is cleared to roll” and she’s off! First easing away under ‘max dry’ the jet engine spools up and Bloodhound rolls to 60mph in about 5 seconds before Andy puts his foot down and engages max reheat (aka afterburner). 20 feet of flame shoots out the back and with a visceral roar Bloodhound is off like a scalded cat, shooting to 200mph in a further 4 seconds and on to 353mph.
Andy then lifted and coasted to 100mph before applying the front wheel brakes to bring the car to a halt 7km down the track. What a great feeling it is when the plan comes together, the car works perfectly and another key Run Profile is crossed off.

These updates are superb. Knowing what is happening and why,makes us all feel like we are on this journey with you. Just keep doing what you do!
One thing is for sure with Bloodhound LSR's record attempt, we are going to get some epic video footage compared to Thrust SSC back in '97
I know right, with this we can see all what's going on and all the data everything and anything. If only it were filmed in 360 degress so we could see it in VR!!!!
@@zerocool6452 Noted!
Apart from the safety aspects, it would be cool to have low flying drones hovering every half mile as the car passes below to give an idea of speed.
@David David Hi David, we've replaced the mic in Andy's breathing mass and the audio is much improved. The flickering screens are simply due to the frame rates. We've tried every variation of screen and GoPro frame rate, and this is as good as it gets. Perhaps w'll have to swap out the camera for a different model in future.
^JT
@@zerocool6452 360 cameras are crap, we just need nice quality normal camera footage nothing to fancy, and 1000mph plus what you gonna see really?
Two steps forward, one step back. T’was ever thus. The sign of commitment is to philosophically shrug off the setbacks, accepting that they’re part of the game of making progress. I admire the commitment and determination of Team Bloodhound LSR. You guys are an inspiration to us all! SO proud of you all!
I believe it took over 60 runs with Thrust SSC to work up to the current record!
Because of the time that has passed and the excitement created at watching the car speed down the course at amazing speeds, we often lose sight of everything it took to first create what the car needed to be then 2) putting it together. So many pieces that were the first of their kind...beyond amazing engineering
I cannot wait for the sonic boom off this beast!!! The 1997 footage of Thrust SSC and the crew reacting to the boom is incredible.
Keep up the great work! Such an amazing project and inspiration
I hope you get some good tv coverage in the UK. You certainly deserve it flying the flag...thx guys ...what a job 👍
I'm loving every minute of this keep pushing Team Bloodhound
Thanks for updates & good luck! :-)
Stick with it guys you've built an incredible vehicle
Awesome work folks, fantastic. My Mrs did about 750 in Lidl car park on Sat when her handbag jammed on the go pedal, I was bricking it!
Hi. I think you may need to look at using a neutral density (ND) filter on the internal cockpit camera. That would allow a slower shutter speed whilst maintaing reasonably correct exposure and may help with the apparent flicker on the display screens, greatly adding to the value of and interest in these videos. BobUK.
Godspeed! 🇬🇧
Great footage well done guys.👍🇬🇧🍺🤘
Dear Bloodhound team, is it possible for you to use a better method of voice capture for both sides of Bloodhound radio please?
Its just a shame the camera framerate makes the dash screens scroll so it hard to read details...amazing footage well done...
I just have to thank you all in your team for listening to your fans about suggestions and stuff, that shows how much you really care. You're the gratest and I wish you all luck and your safety.
The high is the land speed record.
The low is the low speed testing
Fantastic Technology and an awesome machine - well done to all involved - Just a thought what is Bloodhound like in reverse (LOL) - We are all very proud of you - Kind regards Clay.
7 Km... with max speed the track will soon be short. Nice work !
This is some amazing content
Will you be doing any testing in the United states???
Also would a very Interested fan be able to witness such an amazing once in a lifetime spectacle???
Love the videos keep them coming ecstatically the technological ones!!!
First of all big fan of what you are doing out there.
I’ve been enjoying all the videos you’ve been uploading.
I have a question.
The steering wheel gets moved A lot. i’ve seen it do almost 180° in around a second. (about 37 seconds Into this video)
if you did that in a normal car you might flip it.
How many degrees do the bloodhound wheels move in comparison to the steering wheel
for example
If the steering wheel move 10°
How many degrees do the wheels move
Love these videos. My question is a few videos ago you showed damage being repaired to the underneath part of the car. Although this was not a structural item the car was not travelling anywhere near maximum speed. Is this being redesigned to be more resilient at high speed?
No, the damage has been repaired with a thicker material.
Old engineering saying... hardware seldom works first time... software never does.
Presumably the people giving it the thumbs down... don't understand !
May I humbly enquire what the actual run date will be? The progress has been outstanding, but the actual effort will be THE most exciting. Your efforts are not without effect!
Andrew Turnbull - Late next year hopefully.
Many more years yet...they have dragged this out longer than Coronation street 🙄
@@James-oo1yq Or Project Binky 😀
I thought for moment they was using a giant elastic band to stop Bloodhound 😂
SUGGESTION: Dust cover for the intake when Bloodhound is being towed by the truck. That dust has to be very abrasive and it will get into everything..
There is a dust cover - see 0:17
@@triestelondon Thank you! You're right. The black cover was hiding from my old eyes.
Getting squirrelly there eh 😄
I was thinking about the steering wheel, in that if there was a accident will it spin out of control and harm the driver because it looks very sharp and jagged. Does it break of or does he just hold on too something else?
That Ford Ranger though...
I love everything about this project but the Soundsystem is 1960s
Quick Question.... Could you reverse the thrust from the jet to help the car slow down, (like in a plane)?
dataxtractor - No. Thrust reversers on planes are huge and heavy metal buckets attached to the rear of the engines.
@@AtheistOrphan Thank you very much for your response. I understand. I have seen slots opening in the sides of the jets on planes in the opposite direction to the air brakes which deflect the thrust forward. Obviously they have to be capable of withstanding great heat and stress from the braking operation and weight is also a big consideration. Progressive parachute breaking i.e. more than one deployed at strategic points on the braking curve is (I guess) how you are stopping the car. Simple and effective. Thanks very much. Good luck and Godspeed from Newport:)
It might create a dust cloud and then enter the engine. Airlines are using reverse thrust at 160mph. This car is going 300-400-500mph.
@@sanfranciscobay Very good Point! Thanks very much indeed. Best Regards.
dataxtractor - I think the weight penalties would be too much. No jet car has ever had them and every gram in weight saved means more speed.
Do you have to repair the track after every run? Or is it just as & when?
They are using a fresh parallel track each run. I'm assuming they have enough tracks to not use each one more than once, but I'm not sure. Then during the off-season the pan will flood and create a nice new track for next year
Still curious as to the diameter of the drag chutes.
0:18 that’s the only time that truck can says it’s gone faster than bloodhound 😊🥴
Hey what was that? Is there a switch at full left turn of the yoke that signals crew or computer of an event?
If that isn't the case, I'll assume it's just so Andy has room to get his legs out.
Who was the designer of this vehicle?
Reason that I ask is because if there would be some sort of hard hit that would cause this vehicle to break up, where do you think the driver would go?
what's the difference between the first couple versus the last majority
Sound fixed!!!
the track is so narrow that I can't convince myself that it's stable...
Ladies and gentlemen, WE HAVE RADIO!!😃
Where are they going to attempt the 1000mph run? Black Rock?
Same place.
Take my energy guys! \😣/
When you're driving along and realise the handbrake is half on. 0:29
I bet Craig breedlove is laughing his ass off watching all this fumbling around.
Ahhh fix the shutter speed on the cam XD i want to see the screens !
Another idea is to record each screen and then edit the final run video after with screen in screen for a total of 3 screens plus the cockpit view. Should be doable.
What sort of G- force is Andy likely to experience during the run?
I would guess 4G under acceleration. Piece of cake for Sir Andy Green though.
Time to do the big one 1.000
Dan Peltier - Next year when the rocket is fitted.
@@AtheistOrphan Actually not then - that will be the Land Speed Record attempt - around 800mph. If they get the finance to kepp going, then I've read that the 1,000 mph attempt will be the following year.
Martin Ayton - Fingers crossed they get the necessary finance.
Steering issues?🤔
its not as dramatic as you think. The steering is geared differently, nothing like a road car. You don't want to have sensitive steering when going at high speeds as a slight adjustment could be costly.
Sam Kershaw Oh of course, I understand that Sam, I know the steering system on such vehicles is completely different to a normal road car etc. I just wondered in regards to the title of the video and some of the footage seeming to concentrate on the steering.
@@Simonize41 Ah, my bad. I thought the title was just in relation to the day they've had with technical issues and it not being smooth.
The design will have big problems on the underside at speed. Its already requiring repairs.
The repairs have held up pretty well actually. But of course there may be further damage at higher speeds. Nothing that some gaffer tape can't fix though!
Where will the rockets go???
Below the jet engine.
@@anglosaxon1622 are there any videos showing the full design?
This is the strangest looking car in the history of racing. It looks like a 60s fighter plane ran into the back of a 90s bonneville salt flats car....yikes....
3rd
Worst video description ever.
Great description, just need to read the blurb on the description for it to actually make and sense. I felt the same as the video itself didn't seem to describe either feeling.
I assume you're joking, it's a fantastic description!
Oh great. I'm washing my marmite jars out to try to save the planet and that thing is burning aviation fuel !!! Hope it's got a catalytic converter fitted!!!
