A rough approximation of a liquid-vapor methane cooling. Same reentry conditions as the previews post. Up to 30 tons methane required for cooling. In this simulation I am injecting the cooling fluid from a single collector "pipe" directly over the bottom part through the entire length of the double bottom shield space. The methane vapor vents through channels on the upper horizontal part of the shield. I am working to refine the cooling system.

Surface temperature plot of Starship /tile protection/ top and bottom part with very mild reentry conditions - only 5000m/s speed, AOA=70 degree and  atm. pressure only 10 Pascals. As it is seen the shield temperature well exceeds 3000K in about 40-50% of the surface.

 Starship shield upgrade which would decrease the thermal load in critical areas as flap hinges. As well this design makes the Starship aerodynamically stable during the reentry, which allows to replace the rear driven flaps with fixed wings as a part of the shield. The forward flaps would be enough to keep the angle of attack and perform the belly flop maneuver.
