i'm not sure about apaches, but the pumas have MPAIs and it's
not meant to filter out moisture or salts. The only way to protect
the aircraft from all that salt is daily structural and compressor
wash.
Once the aircraft comes back to land, there's is still some major
washing to do.
Foldable blades, it should be possible if they use 2 pins to hold
each blade.
But if the aircraft is to be left there for some time, exposing the
pins will result in faster corrosion due to the environment. The
pins need to be lubricated... and for it to be lubricated, u need
to raise the rotor blades which needs a mechanical hoist, which is
available only indoors.
Deployment on the LST is not as easy as most think, just putting
the aircraft on the ship and activating it as and when. Most don't
see the logistics that go through behind it, they don't see the
extra equipment that needs to be brought on board, they don't see
the manpower a squadron sacrifices on land, they don't know that
the navy supplies only a certain type of fuel which is not the
"best" fuel for that aircraft.
As most of you know that SAF is pretty ngiao... so when a
detachment leaves the squadron they take along tools with them. And
sometimes those remaining in the squadron can't work on the
aircraft because the tools are not available.
Anyway this is referring to those ideas about leaving the aircraft
on the LST on patrol and standby
