Optimizing Performance, Stability & Robustness in Defense Aviation with Advanced CFD Simulation

CFD technologies based on LBM solve complex flow problems in the defense sector. While many believe LBM tools like SIMULIA's PowerFLOW only handle low-speed flows, we have expanded this technology over the past decade to manage transonic and supersonic flows up to Mach 2.

PowerFLOW simulates highly unsteady flows much faster than the competing Navier-Stokes tools. It resolves geometric details critical for flow separations and provides superior accuracy through low dissipation. We pair this with SIMULIA's Navier-Stokes based 3DEXPERIENCE Fluids solver to handle traditional steady-state simulations.

This replay explores workflows customized to the requirement of different types of defense aircrafts: large defense aircraft (including fighter jets, bombers, large UAV/UCAS and ISR aircraft), tactical drones, missiles and space launch vehicles.

• Unsteady aerodynamics simulations at the flight envelope edges
• Vibrations of sensitive payloads in fighter jets, missiles and launch vehicles
• Mission-specific ground noise predictions for drones
• Complex aerodynamic, aeroacoustic and thermal workflows for turbomachinery

We close by introducing MODSIM, our solution that unifies modeling and simulation on a common data model within a single user experience on 3DEXPERIENCE® platform.
