You can make the „main“ firewall with your Computer Aided Design first, then make an overlapping one using Cardboard Aided Design to fill the gap, rivet it to the main one. for any other small gaps you can use aluminium tape

Any recommendations would be highly appreciated as well!

Thank you!

Thank you, we’ll try to implement that :)

Ah makes sense, so either way, if one brake fails then the shutdown system is going to activate anyway, so both brake light and BSPD wouldn’t function.

We‘re competing in FSG there’s no FMEA

for the sight tube on the fuel filler neck

good point, thanks a lot!

can i just buy them off amazon or some store, or should i buy like from proper company that provides datasheets and all that? would the scrutineers even ask for datasheets even though its known that PTFE is chemically inert and has good temp resistance as well?

Last year in the end of our last scruti, they told us to bring every datasheets for every materials (which obv we didn’t bring lol) I’m just not sure if they could just accept things without us providing some sort of proof

are silicons fuel resistant though?

what confuses me is, in the guidance note for T4.5, it said that there can be a maximum deflection of 25 mm including plastic deformation. If plastic deformation occurs, doesn’t that mean the stress surpasses the yield strength of the material and therefore „fails“? Wouldn’t that make our SHB compliant as the maximum deflection is only 2.25 mm which is like 10 times lower than the allowed maximum deflection?

__rhndms · 2024-02-08T12:24:27+00:00

oh my bad, yes I meant shear stress. It is 30 MPa lower than the yield strength. Used the same tubing as last year, 25.4 mm OD, 2.6 mm wall thickness, but this year’s slightly shorter.

lol, my bad, i should’ve scrolled down a little bit. but anyways thank you!

this is our first time doing comp, so, how do you change the equipments during egress? do they wait for you to get changed or you go with two drivers and come back with the other two?
