So they dont test with new planes then? So when the boeing 767 was released it wouldn't have been tested with a lightning strike simulation?
They test it with maths and physics. No need to actually test it physically when they can do simulations e.t.c.. on computer.

:lol: yeah id much rather be burnt to a crisp :o

What does it matter, the plane gets hit by lightning the charge normally dispurses straight thru it, the plane has a earth line over it for purposes of keeping the charge outside of the plane, plus the pane is in air, not on the ground, so you cant really be electrocuted, just burnt

Pretty sure alot of the flight controls systems have anti-lightening strike circuits built into them, so they can cope with the spikes created. The Aeroplane itself also acts as a Faraday's Cage so does help alot with "rejecting" the energy created by the strike :look:.

i think because the lightning passed through the aircraft, but the skin picked up enough charge, and the second flash was the discharge


Skinz

posted on 17th Aug 05 at 15:26

why did the lightening hit, then go then reappear again when the body flashed?


Cybermonkey

discharge into the air from the aluminum skin


Skinz

what caused that imense flash?


Cybermonkey

posted on 17th Aug 05 at 15:19

none at all, aircraft are hit everyday by lightning. just a bright flash outside is all you would see.
last aircraft to crash from a lightning strike was 40years ago, a 707 got hit and vapours ignited in fuel tank

fook about what effect on the people inside do you think that had


Cybermonkey

as you can see in this link, the aluminum aircraft airframe is a very good conductor

i am not sure, but i highly doubt it. would be a pointless and costly simulation

Yes they do, its called the sparksim2004EGH7ES

ww.google.com will tell you that much :|

But do they simulate on a new plane before its released?


richard_syko

posted on 17th Aug 05 at 14:41

There is a place in Germany where the can make lightening, was on top gear years ago.

Its okay to be hit by lightening.

Just knocks a few instruments out.

This is probably mainly for Cybermonkey, but do they have some sort of simulation for testing lighting strikes on new planes. I am in debate with my boss and I need to know this/
