equipped with specialised armour to protect them against impacts
from micrometeoroids or fragments of space junk. Modern aircraft
powered by turbine engines usually have them fitted with a sort
of armour in the form of an aramid composite kevlar bandage
around the fan casing or of debris containment walls built into
the casing of their gas turbine e
