NASA Simulations Improve Artemis II Launch Environment
To better understand the Artemis Space Launch System (SLS) rocket’s flight environment, engineers turned to a NASA-developed tool called the Launch, Ascent, and Vehicle Aerodynamics (LAVA) framework. Using data from the 2022 Artemis I launch, researchers at NASA’s Ames Research Center in California’s Silicon Valley used LAVA to simulate complex interactions between the rocket plume and a system that pumps water to suppress sound during launch. The system protects the rocket and other equipment from potentially damaging sound waves. The LAVA simulations improved NASA’s understanding of the plume interaction with the Artemis mobile launcher platform. Using this knowledge, aerospace engineers at NASA’s Kennedy Space Center in Florida refined the design plume pressures and adapted the launch platform to endure those pressures for Artemis II, NASA’s first mission with crew aboard the SLS and Orion spacecraft.
