Raptor is non-functional without tilting. That is, it's possible to build rocket where all Raptors are fixed, but that defeats some ideas of Raptors. And I haven't seen tilt mechanisms considered parts of the rocket.
So, while engines without tilting have been used - e.g. NK-15 - Raptors aren't from that category.
- modeless 2y agoRaptor is used in a non-tilting configuration on both the booster and ship. You could certainly design a rocket to get to space with only non-tilting raptors, if you wanted. It would be silly to consider it incomplete without tilt, even if Starship does have some tilting ones too. Consider it two variants if you like, both complete on their own.
- timschmidt 2y agoDifferential thrust has been used to steer rockets for decades, and raptor has the sort of deep throttling capability required for it. Tilting is absolutely not required for anything but landing.
- m4rtink 2y agoYeah - you would still need roll-control, but given there are huge potato smashers already bolted on, it should not be an issue while in enough atmosphere. ;-)
- timschmidt 2y agoYup. In addition to the grid fins, there is the warm gas RCS which could perform roll control.
- literalAardvark 2y agoI'd like to suggest the idea that had they been able to operate it "well" without tilting, they wouldn't have added the mass for it. There's clearly a huge advantage somewhere.
- timschmidt 2y agoYeah, landing. As was mentioned. Not necessary for launch.
