This video shows a simulation of the SLS (Space Launch System) rocket using NASA’s Launch Ascent and Vehicle Aerodynamics solver. For the Artemis II test flight, a pair of six-foot-long strakes were added to the core stage of SLS that will smooth vibrations induced by airflow during ascent. The green and yellow colors on the rocket’s surface show how the airflow scrapes against the rocket’s skin. The white and gray areas show changes in air density between the boosters and core stage, with the brightest regions marking shock waves. The strakes reduce vibrations and improve the safety of the integrated vehicle.
