let's see it in full complete car first, and see what forces it can handle, and whether drivers dont get dizzy.
Mate, that's made out of the same material as Jet fighter canopies (Opticor), they would be bothering if it couldn't do the job.
mate, a jet fighter windscreen is a full canopy, enclosed and added with steel frame reinforcement, something totally absent here. let's see some crash tests (like the way the FIA propelled wheels at prototypes) and see that first.
yeah sure it is, at the very back.
The real Jet Fighter canopy was fine, but their bodge-up wasn't. The Jet Fighter canopy was obviously properly engineered.
The goal is not to stay intact. The goal is to take enough energy out of an object to cause no or less harm. That is hard to judge from a video. So the screen may or may not have performed, but eithout careful analysis of the footage and access to shock data you wouldn’t be able to tell.
Agreed, the canopy shattering is no bad thing if it protects the driver first - better a retirement than a casualty. The main issues I see are soiling and visual distortion. This screen already has an advantage over the FIA shield in that it has 1 plane of curvature rather than 2, but being thick plastic you can already see some distortion in the head-on view. We'll have to wait for Dixon's report after the test to know how severe it is.Edax wrote: ↑03 Feb 2018, 11:37The goal is not to stay intact.

E.K. for a 2lb (0.91kg) bird at 460km/hr is 7.4kJ - an 11kg (25lb) wheel and tyre at 240km/hr is 24.4kJ.
missing the point completely again. a full closed canopy has a completely different structural integrity, especially with a hoop at it. offcourse it's completely closed, it's a jet fighter. but that is what gives it it's strenght.djos wrote: ↑03 Feb 2018, 01:46yeah sure it is, at the very back.

The F-16 is designed to withstand 2 pound bird strikes at ~460 kph without damage:

PS, I have seen mention they are rated for birdstrikes @ up to 550kts (1,000 kph) but I cant find a solid source atm.
ignorant response for the win. with such clueless responses, i don't even know why i took the effort to reply to you.
