In 2017 Colorado based company Ursa Major Technologies put together an expert team of designers and engineers to realize its vision of providing the microsatellite industry with the best rocket engines in the business. Utilizing Ansys simulation software, additive manufacturing, and modernizing staged combustion, the company successfully designed and built two liquid oxygen and kerosene engines and has a third engine in development. With Ansys, Ursa Major Technologies is accomplishing design goals faster and more efficiently than ever before. Using Finite Element Analysis (FEA), the company can run models with 30-40 unique parts to analyze entire turbo pumps in one simulation. Thrust analysis, which the company had previously done with 2D models, can now be done all in the Ansys CFX tool more cost-effectively. Join PADT and Ursa Major Technologies for a brief overview of applications for Ansys in the aerospace industry, followed by an exploration of how they are using these simulation tools to better design and optimize the next generation of rocket engines.
