| 21. | One of its three main engines has a new fuel turbopump that is making its launch debut.
|
| 22. | A static firing test on the pad would expose the sustainer turbopump to the failure mode in question.
|
| 23. | Compared to a turbopump the pistonless pump is a much simpler design and has less stringent design tolerances.
|
| 24. | Composed of twin motors with separate combustion chambers and turbopump machinery, it is considered a single unit.
|
| 25. | But in a hybrid, the fuel is solid and cannot be fed to a turbopump's engine.
|
| 26. | The turbopump was used to transport fuel and oxidizer liquids under pressure to the rocket engine of the V2.
|
| 27. | During orbital injection, the GATV engine experienced a drop in turbopump speed lasting about 2.5 seconds.
|
| 28. | Technology lessons from the Low Cost Pintle Engine project were used in the development of the SpaceX FASTRAC turbopump.
|
| 29. | One of the three main engines has a new high-pressure fuel turbopump that is built without any welds.
|
| 30. | The high-pressure fuel turbopump in each engine was built without welds, making it more reliable and safer.
