@SmileSimplify @SpaceX We tried to design a way to save B1046, but not possible 😞

@annerajb Hard gothic

@d1rtydan Haha

We are trapped in a prison of fonts

@flcnhvy @Erdayastronaut @BocaChicaGal @NASASpaceflight Yes

@RQuiddich Every tank under pressure is a balloon tank — it’s just question of degree. Starship tanks are not balloon tanks like Atlas in sense that they don’t collapse when depressurized on the ground.

@Erdayastronaut @BocaChicaGal @NASASpaceflight Everything is compressible, but liquid compression at these pressures is not significant. However, the tanks do expand under pressure, creating a bit more volume. Keeping propellant super cold has a big effect on density of ~10% in case of CH4.

@Erdayastronaut @BocaChicaGal @NASASpaceflight A given tank pressure is needed to feed the engine turbopumps & pressure-stabilize/relieve compression load on the cylinder walls

@Erdayastronaut @BocaChicaGal @NASASpaceflight Dome to barrel weld made it to 7.1 bar, which is pretty good as ~6 bar is needed for orbital flight. With more precise parts & better welding conditions, we should reach ~8.5 bar, which is the 1.4 factor of safety needed for crewed flight.

@rainnwilson Great idea
