ABSTRACT: This paper presents a detailed comparison of the optimization results for distinctive rocket
interstage design concepts. The complex cylindrical grid structure has to withstand the mission loads while
being as light as possible. For the efficient use of the superior material properties, carbon fiber reinforced
plastics are combined with a foam core to form a sandwich ...
