If "debris puncturing through the floor is overlooked is simple." is aimed at me, then I think you have misread my post, or just missed the point i was putting across. I was referring to the Floor being damaged on the Halo as it enters the cockpit.
Just out of interest, how many examples of serious injury because of head debry has their been in open wheel racing ? and of those how much will the Halo help, just as an example the Halo probably did nothing for Massa in 09.
I have Justin Wilson, Henry Surtees saved by the Halo, and WIlson would have been saved by the canopy. So only Surtees would have been saved by the Halo alone.
I dont know about Dan Wheldon could he have been saved, the forces involved were mesmerising. So thats a debate not worth getting in to.
Serious injuries where the Halo would do nothing,
Massa 09, Schumacher 99, Hakkinen 95, Billy Monger 17, Jules Bianchi 16, Sergio Perez 11, Robert Kubica 07.
These were just examples i could think of , of the top of my head. Im struggling to see how you can call Big debry to the head as the biggest contributer to serious injury?
I don't think it would have necessarily have helped Maria de Villotta either as the tail-lift could quite easily have gone in the gap under the halo.
please, don't bring up totally untruthful arguments like that.
the halo can resist the force of a london bus.
maria's case, the car itself would have 'dived' under the truck's loading platform / rear door. the rear door of the truck itself also is 'flexible' to a degree that the arm will move up or down depending on the load is pressured on it. the speed and force maria's car would have carried, paired with the strenght of the halo, would make maria's car both 'dive' and push it downwards by the marussia's own suspension, and would similarly 'push' the loading platform 'upwards'. there would not be the full entire force of the truck's weight put on the halo.
the front of the halo is forward enough from the helmet. maria's car would have to hit the loading platform diagonally on it's most extended corners to have it be able to penetrate - in other words, the car would have to be sliding in a 45 degree angle - without slowing down and without changing direction - for the corners of the loading platform to have a chance of passing through the opening at the halo.
come on, be realistic.
again, as for Bianchi's accident - the abrubtness of the stop would not have been changed whether the halo did or did not exist, so that G-force itself would have remained the same and that specific damage to bianchi would have been the same.
however bianchi's helmet had hit the caterpillar loader, causing additional shock and damage. that would NOT have happened with the halo - also, the halo is able to withstand the weight of a london bus, so it's reasonable to believe that also in this case, bianch's car would have 'dived' downward, which would have meant his helmet would not have hit the caterpillar, and the car itself would have had further damage, perhaps even taking some minor extra energy out of the equation and thus the total force inflicted. the top of the car was already taken off bianchi's car, the halo would simply have protected the driver's head from ever getting an impact. the shape itself - again - makes it possible the halo doesn't get the full (exponential) damage from the collision , it would have taken damage and deflected it by 'lifting' the truck upwards (the force itself already moved the caterpillar) even further, aswell as further 'diving' the car downwards.
whether that would have saved bianchi's life is another question alltogether
but you can be guaranteed that it would have inflicted
less total damage and thus, his chances - as remote as they were - would have been ever so slightly bigger, and
that might have meant the difference between life and death. if it would have finally resulted in the possibility of recovery or being permanently braindamaged and confined to a wheelchair ala stephen hawking-style is another story alltogether.
but if we're looking at increasing chances for survival, the halo
does work for even bianchi's crash.
there is simply
no way that the indyscreen would have had any difference on bianchi's crash, and i am doubtfull whether it would have in devillota's case. the RedBull aeroscreen
might have, as it essentially is a halo with a screen attached to it. however, if i'm not mistaken, the aeroscreen like the indyscreen slopes down on the sides and exposes part of the driver's helmet, whereas the halo itself 'tops off' at the helmet. a flat object [unlike a wheel] will thus not be able to hit the driver's helmet top-side.
i agree though that there is still a chance that the top of the helmet, in the centre of the halo, might still be hit by a wheel since it's shape allows it to enter the opening inside the halo - if it hits it under that 'perfect' angle. just a few cm's to the side and it bounces off the bar of the halo.
in case of the indyscreen and the aeroscreen, both protect much less than the halo in that case, aswell as bianchi and devillota's case - ALSO in schumacher-liuzzi crash.
hence, the halo
remains the safest solution.
it's really not that hard.
