The durability of the
product is influenced by
the severity index:
-
with reference to Tab. 3.1,
-
according to the type of
10
piston, the weight and
20
the length of the wing
30
and the use conditions,
10
different corrective fac-
20
tors were estimated, the
sum of which influence
the operator durability
(see Tab. 3.2).
