Keynote: Using COMSOL Multiphysics® for Rapid Prototyping
Duration: 11:28
In her keynote talk from the COMSOL Conference 2020 North America, Lauren Lagua shares how Northrop Grumman Corporation (NGC) performs rapid prototype design phases for sonar systems using multiphysics modeling. This approach has been especially beneficial at NGC for determining unknown material properties and manufacturing defects during production. In addition, Lagua discusses how this rapid prototyping method was used to design a synthetic aperture sonar for unmanned undersea vehicles (UUVs).
Lauren Lagua is an acoustics engineer at NGC in the Undersea Systems Division, where she focuses on sonar transducer design, manufacturing, and acoustic testing.
