Isogrid on the interior of the adapter connecting the Orion spacecraft to the Delta IV rocket for Exploration Flight Test 1
Isogrid is a type of partially hollowed-out structure formed usually from a single metal plate (or face sheet) with triangular integral stiffening ribs (often called stringers). It was patented by McDonnell Douglas (now part of Boeing).[1]
It is extremely light and stiff.[2] Compared to other materials, it is expensive to manufacture, and so it is restricted to spaceflight applications and some particularly critical parts of more general aerospace use.
