  2. Cost Modifiers • Balloon Cost Modifiers • Balloon – Price quote from Aerostar International • Helium – Priced at $4.87 per cubic meter • Gondola • Cost Modifier • Tubing – Based on given pricing and scaled per stage • Handling – Personnel required for handling of fuels, toxic materials, etc • Ground Support – Based on estimation of salaries of necessary personnel AAE 450 Spring 2008 Group Name (i.e.Trajectory Optimization)

  3. Table of Costs Future Work • Finish CAD Modeling • Report Write Up on Balloon and Cost Modifiers AAE 450 Spring 2008 Group Name (i.e.Trajectory Optimization)

  4. Gondola (Backup) Mass 288.4 kg of Aluminum Cost $1205.3 Provided by Sarah Shoemaker and Structures Group Credited to Sarah Shoemaker AAE 450 Spring 2008 Group Name (i.e.Trajectory Optimization)

  5. Structures Gondola Code (Backup) • function stress = gondola_strength(GLOW, area, gond_weight) • g = 9.80655; • GLOW = 6290.6899; • area = .787; • gond_weight = 84.533; • force = (GLOW + gond_weight)*g; • stress = force/area; Credit to Structures Group

  6. Structures Gondola Cost Code (Backup) • function cost = gond_cost(gond_weight, length) • length = 2*.04*4; • gond_weight = 84.533; • time_weld = 1/.6*length; • num_rivet = length/.1524; • cost_rivet = .73; • labor_cost = .049; • cost_labor = 52; • rivet_cost = cost_rivet*num_rivet; • labor_hr = labor_cost*num_rivet; • Labor_cost = cost_labor*labor_hr; • mat_cost = 13.23*84.533; • weld_cost = 150*time_weld; • riv_cost = rivet_cost + Labor_cost; • cost = mat_cost + weld_cost + riv_cost; Credit to Structures Group
