Abstract
Intertanks, the structure between tanks of launch vehicles, are prime candidates
for weight reduction of rockets. This paper discusses the optimization and
detailed analysis of a 96" (2.44 m) diameter, 77" (1.85 m) tall intertank. The
structure has composite face sheets and an aluminum honeycomb core. The ends
taper to a thick built-up laminate for a double lap bolted shear joint. It comprises
8 full length panels joined with bonded double lap joints. The nominal line load
is40001b/in(7*10*N/m).
Optimization is by Genetic Algorithm and minimizes weight by varying core
thickness, number and orientation of acreage and build-up plies, and the size,
number and spacing of bolts. A variety of cases were run w
