Impetus DEFENSE: Ballistics Simulation for Aerospace & Defense
Impetus DEFENSE is a software modeling system that provides accurate, 3D simulations of the extreme physics of combat ballistics. Used by vehicle and armor manufacturers, munitions, missile, and drone designers, and structural engineers, Impetus offers a full suite of GPU-accelerated analytical tools for a wide range of modeling applications and simulation methods.
Impetus DEFENSE provides four physics-based, computational engines including Finite Element Analysis, Discrete Particle Dynamics, Smoothed Particle Hydrodynamics, and Computational Fluid Dynamics. Impetus DEFENSE also includes two additional tools, Vulnerable Area Assessments and Vulnerability/Lethality, plus Impetus MARKET, a comprehensive library of digital twins of inert and energetic materials, munitions, and other objects to accelerate analyses.
Impetus is ISO 27001 certified, and the software is available for on-premises deployments to desktop workstations and large networks including GPU clusters. Licensing is managed per entity and project, not per user, so organizations and engineering teams can work collaboratively and effectively.
Modeling Drone Attacks
FPV drones have changed the game in modern warfare. With Impetus, armored vehicle manufacturers and field adaptation engineers are now able to simulate drone-carried shaped charge and high-explosive attacks with accuracies previously available only at national laboratories and major prime contractors. For both UAS and counter-UAS design and simulations, Impetus DEFENSE can reduce the significant financial costs and challenges of physical testing and evaluation.
Shaped Charges & Target Interactions
Impetus DEFENSE provides processor-efficient simulations by combining Smooth Particle Hydrodynamics for shaped charge munition liners and casings along with Finite Elements or Computational Fluid Dynamics to simulate explosive materials. Shaped charge jet length, shape, and velocity profiles and particulation data are produced automatically, and effects are rendered visually in Impetus' smart user interface. Impetus DEFENSE includes built-in templates for common shaped charges and explosively-formed penetrators.
Fragmentation Modeling
Impetus specializes in fragmentation modeling with advanced finite element analysis tools. Impetus DEFENSE calculates high-order finite elements for large deformations, provides stochastic distributions of initial damage from varied fragments, and node-splitting algorithms to prevent material loss in simulated fractures. Impetus ensures accurate, physics-based simulations of explosive and reactive fragmentation processes that are crucial for modeling in defense and civilian engineering. In addition, engineers can import fragmentation distributions directly into the Impetus user interface for subsequent Vulnerability / Lethality analysis, along with interactions of user-defined ground targets.
Blasts & Structural Interactions
Impetus DEFENSE's GPU-accelerated, ultra-fast Computational Fluid Dynamics tool is ideally suited for air-blast simulations, particularly contact detonations and urban blast scenarios. Impetus also excels in calculating intricate fluid-structure interactions, such as mine blasts and effects on geometrically complex vehicle models. This combination enables deep insights and the ability to mitigate IED and other blast effects on a variety of stationary and mobile structures and their protections.
Simulating IED Effects
It's well known that the detonation of mines and buried improvised explosive devices (IEDs) can heavily damage armored and other vehicles, and also cause severe harm to personnel inside. Digital Twin modeling of this process can be used to evaluate the vulnerability of a vehicle and its personnel and optimize its protection against such threats. Impetus DEFENSE includes accurate, comprehensive software tools to assess the effects of kinetic energy projectiles, artillery, and blasts from IEDs to STANAG 4569 protection standards (ie MIL-STD).
