  1. TPS Methods Report

  2. Goals • 1) Meet Boundary Condition • 477.95O K • 2) Minimize TPS Mass

  3. Convection hA(Tinf – TWall) (Type 3) ChA(ir-iwall) (Type 1) Time Dependant Heat Flux awAqrad Reradiation ewA(T4wall – T4rad) TPS Material #1 X TPS Material #2 TPS Material #j Heat Conduction Problem

  4. SODDIT

  5. MATLAB & SODDIT number_of_materials = 3; materials(1) = struct('name','SLA-561V.m', 'thickness',.04,'nodes',15,'ablator',1,'mult',1); materials(2) = struct('name','AETB.m', 'thickness',.01,'nodes',15,'ablator',0,'mult',1); materials(3) = struct('name','Graphite.m', 'thickness',.01,'nodes',15,'ablator',0,'mult',0);

  6. SODDIT & MATLAB Material Data Sweep of scale .qw file Soddit_between.m Soddit_control.m Material Data Single value of scale .qw file Mysoddit.m SODDIT _plt.txt .inp File Get_plt_data.m Temp History Thickness History Maximum Time

  7. Teflon SLA-561V AETB Graphite-Epoxy Code Validation TPS 1 TPS 2 5cm 2cm 1cm

  8. Heat Flux

  9. Temp History

  10. Ablation Comparison

  11. SLA-561V AETB 5cm Graphite-Epoxy 2cm 1cm Test Case • Completed 600s Mission Duration • Inner Wall Temp meets 477.95O K Boundary Condition

  12. TPS Minimization Scale = -.42

  13. SLA-561V AETB 2.32 cm Graphite-Epoxy .58 cm 1 cm Weight Savings Original Density  37.83 kg/m2 Minimized Density 29.2 kg/m2 23% Savings over Reference!!!
