  2. Structural Sizing • Matlab function call (Brandon White, CJ Hiu) • Automated Tank Size and Weight Calculations • tank material & propellant type • insulation • Sanity Checks • wall thicknesses • tank aspect ratio • automatic shape control • Interoperability with Prop & master code (Yaple, Bluestone, Wilcox, Lattibeaudaire, Schwing, Rhodes) AAE 450 Spring 2008 Structures

  3. Findings • Cryogenic Tanks problematic • Carbon Fiber attractive? Steel unattractive Future Work • Cost function calls (David Childer) • Advanced Tank Options – Compound/Tandem/Carbon Wound • Tank & Interstage internal structures (Structures Group internal division) • Engine Masses • MAT Teams to crunch through permutations AAE 450 Spring 2008 Structures
