A size comparison of the SLS booster and RS-25 engine nozzles (two-percent scale models) to a quarter.
Two-percent scale models of the Space Launch System (SLS) solid rocket boosters and core stage RS-25 engines, which will power the vehicle to deep space missions, have been designed and built ahead of base heating testing scheduled this summer. The current model RS-25 engine clocking configuration, different from the SLS configuration, is used to adequately visualize plumes during the Pathfinder Test Program. The work was a collaborative effort between Marshall Center engineers and Calspan-University of Buffalo Research Center Inc. in Buffalo, N.Y.
This image shows a size comparison of the booster and engine nozzles to a quarter.
