Acoustic Simulation for Spacecraft Launch

Launching a rocket into the sky is not an easy thing. There are several thousands of unimaginably complex engineering processes occurring in the background, the competition is getting tougher every day, and companies frequently only have one chance to get the launch sequence right. So what is hindering efforts to launch more powerful rockets in order to reach higher lift capacity and go further in space?

During these powerful lift-offs, a rocket is being exposed to many different forces. This means that payload components like satellites or antennas are exposed to intense acoustic excitations that can damage their structures. These excitations may include Turbulent Boundry Layer (TBL) which happens due to the air viscosity and on the surface of the fuselage, Diffuse Sound Field (DSF) applied to the structure which happens because of the engine noise at the lift-off and also structure vibration during the launch. One of the challenges in the space industry is accurately modeling these vibro-acoustic problems and predicting the vibration levels of infrastructure.

With an acoustic simulation software, companies will be able to predict all the damages that can happen and make the improvements in the early development stage. Additionally, fixing these problems early on and in a virtual environment will help companies differentiate themselves from their competitors and avoid launch failures. MSC’s acoustic modeling and simulation toolkit offers a unique solution to accurately and quickly study the influence of the acoustic excitation on the component structure. It can be used to accurately model structural vibrations, fluid-structure interactions, and turbulence noise propagation. It can output all the required quantities to perform a complete analysis of the system response thanks to its wide material library.
