I don't think that shunt anchors are probably a workable idea, but I love the thought and the discussion!

Makes a very refreshing change from some of the other threads.

I think it would be potentially problematic to have something which deploys automatically in the event of an impact or lateral motion. Surely it would be going off at unintended moments.

Would some sort of airbag(s) system in the cockpit all round the driver to shield them from an impact be in any way feasible?

Looking at Max accedent, and a few that come to mind, the car was 'skimming' over the gravel so scoops would not have filled up. If the 'device' wad long enough and powerful enough to be of use in those case, would it not be powerful and long enough to cause a flip on cases where the car is on the ground or it is tarmac or concrete?

I think gravel traps is a shrinking market.

For asphalt the best friction comes from the 4 rubber round things. A stabby grappling hook will never get deep enough to scrub speed because the impulse at the instant of grab needed to get deep enough into the surface will just rip the hook or asphalt out.

Sunday was sort of a good advert for the much maligned tarmac run off areas. I think somewhere like Bahrain or Paul Ricard, especially with the ultra abrasive red stripes, there's a chance the car slows significantly or even stops travelling before it hits the tyres. Then of course you're back to track limits. But which is the lesser of two evils? Tarmac plus better track limit management may be the way.

You think they could rubber coat the 'plank'? :mrgreen: stop em kerbing anyway.

Shallow trench with chamfered edges. Fill trench with water or water and astroturf. Tyres get wet / cooled. Slows driver directly and by affecting grip until those tyres are warmed up again. If the car goes past the trench, e.g. spinning, then it's back on to high grip asphalt to slow it down. Go too far and you get wet tyres. Your choice.

Something like this ripper is an option for gravel but obviously for F1 it would be smaller, lighter and underneath the car. Think of something compact like the DRS mechanism.

The device won't rip into asphalt because the car doesn't have enough weight to make it do so. So that's where some sort of rubber device. As Big Tea said, a rubber surfaced plank would be supplimentary to the anchors. The plank could be lowered to the ground, in addition to the anchors,l mlike a big friction pad.

You're almost there..... but put the airbags on the exterior of the car. Just joking! Re the post above, seems to me having some device extend from below the car will just lift the car reduce the stopping power of tires/brakes and allow the car to slide further, especially on asphalt. Steel hooks (or whatever) would act like ice skates....... with sparks.

Sounds like the jump-jacks from Speed Racer (2008)...

So with that thought, integrating something like a pressurized spike deployment system could become a "secondary" function of an onboard jack like other categories currently use. It would be something like it operates as a wheel jack when under air pressure in the pits, but can also behave like a grapple hook launcher under an explosive charge.

Also, deceleration lanyards should be used between the grapple and the chassis(1-2m). A 51g stop is pretty much the same on the driver if hitting the wall, or becoming instantly stapled to the ground. I'd be interested to see if it could react in a way that it would always tip the car on its side, towards the impact vector, and let the driver ride the shoulder harness vertically instead of horizontally, and study that as well.

I'm kinda down to see it tried. I'm sure a full drive-by-wire test chassis controlled via sim from the pits wouldn't be terribly expensive now adays as it would really just be adding a force feedback motor to the steering shaft with today's "by-wire" control over acceleration and braking, and their Sims all have it already.

The other problem is probably, that although it looks at first you will have a good grip in the gravel, the surface area must be quite large to have any real effect. And If you make it to large, you will have a car floating on a scoop of gravel sliding over gravel.

Although it looks cool, gravel is quite bad at stopping cars, especially at high speed.

That would be great! Like a load of high speed hovercrafts.
