ESI’s vibro-acoustic simulation software VA was used to successfully complete a European Space Agency (ESA) contract. German space application provider Space Structures, a customer of ESI, completed a carbon-fiber composite panel project for the ESA, using VA One to virtually test designs in various acoustic noise environments.

Space Structures was commissioned by the ESA to develop a multi-functional panel for large satellites, and used ESI’s simulation model to ensure the integrity of vital launch equipment subject to high-intensity acoustic field during launch. Building on the company’s experience in building carbon-fiber composite structures for large spacecraft, Space Structures used a new methodology to reduce uncertainties related to the ability of the structures to withstand the launch acoustic environment.

Space Structures intends to continue their use of VA One to improve structural design for all acoustic noise environments.
