Part 7/8:
The evolution of Raptor engines also brings structural improvements, such as reduced reliance on bolted joints, shifting towards more welded connections. While this approach enhances durability, it introduces more complexity concerning maintenance. Servicing the new integrated components may demand more intricate procedures, as technicians can no longer simply unbolt sections but will need to cut and reseal welded parts.
Yet, this trade-off positions SpaceX to achieve a robust engine design that minimizes downtime between launches—critical for their ambitious goals of frequent and reliable space missions. As the company focuses on improving the overall reliability of the engine, the advantages of such a design philosophy might outweigh the challenges of serviceability.
