Definitions
- the invention relates to a turbomachine casing and in particular to a turbomachine exhaust casing.
- stiffeners avoids providing additional thicknesses in the areas concerned and therefore limits the increase in the mass of the structure.
- these internal ribs can take the form of rods 93, 94 provided with complementary heads 93a, 93b, 94a, 94b of circular or square section and of complementary shape (a male part and a female part).
