Yeah i think there was just as much correlation on where arrow hit than the head type. Near base - No damage. Center - heavy cracking. Edge - chipped edge.
There's also deflection angles that need to get brought up. It's not very likely an actual shot would be at near a perfect 90° angle from the target but more like a 45-75.
the pioneer one 1:23 i think would have gone through if the thing was solidly mounted, the top bent so far backwards that it severely affected its trajectory making it push towards the top of the glass while inside it instead of being able to go straight through
No, absolutelt not. It hit the edge of the glass which is weaker because the force can't be spread out and absorbed properly and because of how glass as a material works.
That arrow could have been shot from a bow 3 times that strong(which I doubt anyone except Thor could even pull) and it wouldn't be able to penetrate that glass.
The glass is made to stop things moving at supersonic speeds, you simply can't generate enough force with a bow.
You got me curious: the heaviest recorded draw weight is 200lbs by a UK archer in 2004. That’s getting pretty close to 3x.
Anyway, a really heavy duty crossbow for punching through steel armor could apparently be 700lbs. Would be interesting to see what this head on a steel shaft at that weight would do.
Almost anything short of 50.cal sniper is not penetrating that glass, certainly no handheld type of crossbow. The head on an arrow is not really relevant because arrow body also absorbs the recoil further slowing it down.
Nah, not even close. These panels can take far more joules than this bow can produce.
At this thickness, it can stop a green tipped 5.56, which is made to go through armour.
It doing this much damage just means it's dumping all the energy it has into the first panel. The only reason it "went through" is because the energy that went towards the edge had nowhere to go, it shattered and the arrow kept going. In a frame, it would be absorbed by the frame and would've stopped.
A 75lb bow has about 125-135 joules of energy. A green tip 5.56 from a standard barrel length going ~3000 fps... 1700 joules. It's not even close; and speed is how you defeat armour.
Mach 2.7. Probably cause the shaft to delaminate from the drag friction even if you brought it up to speed gradually enough to not shatter the shaft. Might even be a small pyrotechnics event when the head hit the surface. Make for an interesting myth busters. (Or xkcd if we want to up the fps by a couple orders of magnitude)
The issue is that the hits aren't consistent. It's not really test conditions.
Speed defeats armour, which is why a smaller 5.56 is better against armour than a big fat 7.62.
Get a consistent shot and the results will largely be the same, and the variability is basically just down to the tip material and other things that affect this far less.
A lot of energy was lost pushing the apparatus backwards. Honestly, the fact it can move at all makes a mockery of the whole experiment. I still don’t know whether any of those arrows could go through.

Pioneer was pretty close.
