Advanced Near Net Shape Technology (ANNST) - Integrally Stiffened Cylinder (ISC)

Machined/welded construction of launch vehicle cryotanks is expensive, heavy, and risky. The current state of the art manufacturing of launch vehicles contributes to high cost of launch operations and is based on 1950's technology. This project will use an innovative metals forming technique to manufacture cryotanks, which are cheaper, lighter, and have fewer welds by utilizing a single-piece stiffened barrel in a one step-processing step. This project partners with DLR, LM Denver, ESA, and MT Aerospace.
