Q: why are the grid fins not evenly spaced out as they are on F9?

@elonmusk
Pitch control requires more force than yaw & much more force than roll. Also, grid fins closer to or in the wake of the booster are less effective.

However, pretty good aero control can technically be achieved with only 2 grid fins, with some effect on accuracy.

je to monstrum...

Very close to real! Arms are able to move during descent to match exact booster position.

Catch point is off to side, in case catch fails – don’t want to hit launch mount.

Booster is transferred back to launch mount for next flight.

Designed to have <1 hour turnaround.

SEJDA: zadnej strongback asi ani nebude, kdyz to nikdy nebude lezet horizontalne, ale budou to vertikalne skladat jerabem primo na rampu

TOXICMAN: no jo, kdyz o tom mluvis, tak jsme jeste nevideli, zadne "strong back". Ale, kdyz stavi Starship tak, aby sla dotankovat na orbite, tim, ze se dve spoji prdelemi k sobe .. nebylo by prakticke, aby se Starship tankovala skrze Booster, kdyz uz na nem stejne sedi?

TOXICMAN: cely dlouhy stack se bude tankovat dlouho :D

KAERO: si myslím že není třeba ne? Tlakováni proběhlo při cryo testu u B3 a u B4 proběhne taky. Tlakováni do výbuchu mělo jen ověřovat co vydrží použitý materiál na stavbu lodi. Pletu se? :)

SEJDA: ehm. norminalni. :D

KAERO: svary uz jsou otestovane ma SNxx nemyslim, ze je kvuli treba testovan Bx extra. Jenom natlakovali na nomalni hodnotu.

Toto nie je render
