AAE 450 Spring 2008 Danielle Yaple 7 February 2008 Avionics Group, GC, CAD, MAT Model Analysis Trios Combined Code 1

AAE 450 Spring 2008 MAT Code User Inputs  Delta V (vary case to case, 7000,9000,12000,15000,18000 m/s)  Payload Mass (.2, 1, 5 kg)  Stages (2 or 3)  Propellant Type (Cryogenic, Storable, Hybrid, or Solid)  Tank Material (Steel, Aluminum, Composite, Titanium)  Launch Type (Ground, Balloon,Aircraft) Outputs Model Name, GLOW (kg), Total Cost*, Propellant Costs per Stage, Tank Cost per Stage, Inert Mass Fractions per Stage and Stage Lengths 4 min Run Time Avionics 2

AAE 450 Spring 2008 Sample Data Avionics Future Work  Costs, Trajectory  Make Graphs of Information for Vechicle Decisions 3
