Stuart Galbraith Posted October 14 Posted October 14 Is there any explanation what the fire on the side was, APU perhaps? Very impressive.

DB Posted October 14 Posted October 14 Looks like there is still a bit too much heat coming through the aft wing hinge to be entirely comfortable, but it looks like they landed softly enough that if there hadn't been a post-landing explosion they might have been able to bring it in in one piece. The first stage recovery was awesome, but the quick disconnect arm took a bit of a roasting.
rmgill Posted October 15 Posted October 15 They're not doing any regenerative cooling during re-entry. The fact it's all made of steel (stainless I think) helps for the durability. Composites would not handle that level of repeated heating.
TrustMe Posted October 15 Posted October 15 Would Titanium do better than steel it has better heat resistence?

B-58 and XB-70 were made mainly in stainless steel, so SS heat resistance should be enough. Seems engines are made of copper and a nickel-copper alloy, a SpaceX-proprietary type of Inconel. https://forum.nasaspaceflight.com/index.php?topic=53555.2320
