ATA Engineering, Inc. (ATA) is an engineering consulting firm that provides innovative solutions through test- and analysis-driven design by focusing on the engineering needs of manufacturers in addressing their cost, quality, and time-to-market challenges for mechanical and aerospace systems.

The Challenge

ATA was tasked with fine-tune the existing design of the Space Shuttle Main Engine rocket nozzles for use in NASA’s next generation vehicles and needed to understand the full scope of fluid-structure interaction in the components. Cost-control was critical and field test data was incomplete for full understanding of all parameters. 

Dassault Systèmes Response

ATA employed the SIMULIA Co-Simulation Engine (CSE) capability to link Abaqus Finite Element Analysis (FEA) with a flow solver into a fully coupled structural and fluid dynamic analysis.

Benefits

ATA now has the first-ever, time-accurate, 3-D FSI simulation of a rocket engine nozzle during liftoff; the company was selected to continue their work within NASA’s SLS program.
