Composite launch canisters, boasting unparalleled mechanical prowess, design versatility, and exceptional thermal insulation capabilities, have garnered widespread adoption in the realm of launch vehicles. As the commercialization of space launches intensifies and launch frequencies escalate, the imperative for low-cost launches and low-cost launch canisters has become increasingly pressing. Two distinct strategies for cost reduction emerge: reinforcing launch canisters to amortize costs over multiple usages and developing cost-effective single-use launch canisters. This paper, with a focus on the latter approach, delves into the intricate relationships and variations between the stiffness of launch canisters and pivotal design factors, including wall thickness, layup schemes, and material composition. The objective is to furnish insights that facilitate the cost-effective design of launch canisters.
