Structures Group

Material Selection / CAD

Transfer Vehicle, Mars Crawler,

Construction Crane, Ares V, ISPP


Material selection

Material Selection

  • Traditional Spacecraft (S/C) Materials

    • Al Alloys, Ti Alloys

  • Current S/C Material

    • Al-Li Alloys

  • Future S/C Materials

    • Metal-Matrix

      Composites (MMC)

    • Carbon Reinforced

      Composites (CRFC)


Material application pressure vessels

Material Application: Pressure Vessels

  • Pressure vessels include:

    • -Fuel Tanks, Habitat, Transfer Vehicle (Crew Compartment)

Al- Li Alloys currently used in External Tank

(Code partially generated

by Brandon Anderson)

Preliminary Analysis: Only considered internal pressure as design criteria, future results can result in larger values.

Pressure vessel design

Pressure Vessel Design

Radius = 4 m

-Based on cargo dimension of Ares V

Length of Habitat / TV = 6 m

- Based on Project Legend

Length of Fuel Tank = 25 m

-Based on cargo dimension of Ares V

Fuel Tank

Habitat/ TV
