This is the radome on jet after a bird strike. I kind of imagined it would be constructed like the hull of a fibreglass boat, but it's nothing like it.
Can anyone explain why it's built this way?
MadTux:
These are directional fibers, not undirectional fleeces like on fibreglass boats.
Undirectional fleece is cheaper, but directional fibers, like on that radome has much better strength to weight ratio, because fibers can be orientated so that the load is applied along the fibers.
Can also made thinner this way, so less radar absorbtion/reflection.
coppice:
A boat is not a complete circular structure. When you have a complete circular structure and plenty of money to spend on the strongest possible construction you end up with something like that aircraft's nose. I've seen structures like this being assembled. They put a huge number of hours of labour into getting the fibres set up just right in UV curable resin, and when everything has been inspected and accepted the UV light goes on.
coppercone2:
can you buy an old radome as military surplus to put on a home roof to guard an antenna?
German_EE:
I built a radome once after we lost satellite reception due to snow on the dish. Nothing sophisticated, just a wooden frame covered by a layer of polythene but it was still there when I left six years later.
