How do you stop a 1,000 mph car?

Getting to 1,000 mph is relatively easy, slowing down safely before you run out of desert is much more of a challenge.

At 1,000 mph there will be 15 tonnes of drag pushing against the car.
When the jet and rocket engines are switched off BLOODHOUND will rapidly decelerate to 800 mph at which point the air brakes will start to be deployed. They will open out into the airflow and maintain 3G deceleration (the equivalent of you going from 60 mph - 0 in one second - for 20 seconds).

Once the car slows to below 200 mph, driver, Andy Green will use the more conventional wheel brakes to bring the car to a halt.

This video shows the brake disc testing at AP Racing.

the engineering that's gone into every single piece of this car is unbelievable. I know quite a bit from prepping race cars but this is on another planet.
british engineering at its best. good luck

I assume you're not going to be able to pick these break kits up at Auto Zone.

I saddened when I heard a kiloWatt being used as a unit of energy.

We're told the energy dumped was 4.6kW over a period of 19 seconds.
Clearly nonsensical.
Perhaps they meant 4.6kJ, or, that the peak or average braking power was 4.6kW.

Putting brakes on a bullet? A bloody crazy idea but a radical one !

Maybe a clutch system that disengages the rotor over 170mph. One that's quick change like a multi plate set up in top fuel drag racing. Or embedded magnets within the wheel slowed by electric stator? I have been following this since the beginning and remember watching thrust ssc when I was a kid. Love what you guys are doing. Keep it going- please!!!

I came here through a yahoo.com article.  I wanted to say that this is amazing, and it always impresses me when I see advances like this that can have future trickle-down impact on daily living.  Thank you for your work!

1:40 Guys, getting your units wrong? WTF

I expect greater things from a project that involves such impressive engineering.

[alexw]

was genuinely thinking click bait here I was wrong. kudos sir. liked/ subbed

Burger Van Dreamz by your definition is is a car, bloodhound has 4 wheels, has an internal combustion engine, and carries a small number of people (1). and if not for those reasons, "typically" means that there will be a small number of exceptions. sooo... also its not a plane meant to stay on the ground. if you ever look up the american eagle, they literally take a f104, pull the wings off and put metal wheels on it.

Spit, grit, and a whole lot of duct tape.

[DAIadvisor]

If you just let go of the gas, the air resistance alone will slow the car drastically in just couple of seconds. After that, the chute should do the trick

[foxtrotcamp]

so Just build a tough wall at the end of the runway... the car may look different then, but I guarantee it will stop
Braking the car to a stop is another story... since we're going hardcore, why don't we fit reverse thrust like airplanes do? maybe we'll add a chute or two... the car might get jerked all over the place but once again, I guarantee it will brake
Now for braking the car to a SAFE STOP, I suggest you build an around the world runway and just fucking let it spin Round & round & round... according to newtons' law of motion it will eventually FUCKING stop SAFELY... btw if we spin the car around the world - at the earths spinning speed- in the other rotational sens we may go back to the past, get stuck in a time-space village or something...
that was my contribution for the day...

[Nozerone]

At first I thought it was a typo.

Ooops, they said 1000mph. I think they meant hp.

After watching though... I now know. 1000 mph.... in a car.... on the ground... holy shit!

[dedasdude]

what happened to the magnetic braking system that was used decades ago?

[nikolaiownz]

man i would love to work on something like that.. this project is so impressive!

[markpeters]

Only a thought, but have you considered the prospect of having inboard brakes that were only engaged, via a clutch mechanism at relatively low RPM? That way you could have very powerful carbon fibre or ceramic braking without the risk of having them disintegrate.

[edj]

What were ThrustSSCs discs made of? Surely the new ones would be similar?

[jaytate]

Why not run a engine braking system like on a turbine based plane? Force the thrust to do the stopping.

[timmygunz]

2 sets brakes on each wheel is what you guys are saying. 1 is air brakes the other hydraulic?

[theonlyari]

Why not use a magnet / the Lorenz effect?
