Case Study: Agency for Defense Development advances airframe survivability research with MSC Software Dytran

Agency for Defense Development - Customer Case Study

The Korean Agency for Defense Development (ADD) needed a way to better understand airframe survivability for future military aircraft, especially the damage caused by hydrodynamic ram in fuel tanks. As the first step in survivability design, ADD faced the challenge of simulating complex projectile penetration and fluid-structure interactions that are difficult to model with traditional methods.

MSC Software addressed the challenge with its Dytran explicit FEA solution, using multi-material Euler solvers, adaptive master-slave contact, adaptive Euler meshing, and a multi-porosity algorithm to model flow between tank bays. The approach enabled ADD to simulate hydrodynamic ram effects more accurately in both a single wing bay and a real fighter wing model, reducing uncertainty and improving confidence in survivability analysis.
