Aerospace & Defense Webinar Series
The aerospace and defense (A&D) industry has been at the leading edge of the development and adoption of simulation technology since the introduction of computerized tools. The reason is simple: It works in a high-reward/high-risk design space, in which the cost of failure is too high. An engineering success like the Space Shuttle’s first manned flight would have been impossible without the extensive use of reliable and accurate computer simulations that guaranteed all systems and components were working correctly.
In this webinar series, we will explore how ANSYS simulation technology is used by the A&D industry to design and analyze a wide number of cutting-edge applications, and how simulation can help make these products better and safer.

Thermal FSI of a Sounding Rocket Through Atmosphere
Sounding rockets frequently contain scientific equipment that needs to survive the thermal consequences of re-entering the Earth’s atmosphere at hypersonic velocities. Traditional thermal protection systems have been designed using uncoupled simulation methods that consider the exterior aerodynamic heating and the interior thermal behavior separately, but this may cause simulation results to be incomplete and even misleading.
Join us for our upcoming webinar to discover how fluid–structure interaction (FSI) can provide a better understanding of thermal performance in aerospace and defense engineering
This webinar will consider a typical sounding rocket with simplified internal components subjected to atmospheric re-entry aerodynamic conditions. It will illustrate the capabilities and workflow approaches that can be used to evaluate the thermal performance using ANSYS structural and CFD simulation tools connected via the Ansys Systems Coupling environment.

The New Fluent Experience with Mosaic Meshing for the Aerospace and Defense Industries
We will explore how the aerospace and defense industries can optimize their current workflow and increase productivity with exciting new enhancements in the 19.2 release of ANSYS Fluent.
Through live demonstrations and success stories from early users, learn how Fluent reduces hands-on time and raises efficiency with a single-window, task-based workflow and Mosaic-enabled meshing technology:
- Watertight geometries can be prepped and meshed in a single-window Fluent interface.
- Task-based workflow guides you through the simulation process by presenting best practices in an organized interface.
- New users learn faster, while experienced analysts gain efficiency.
- Mosaic uses high-quality polyhedra to combine any type of boundary layer mesh with autogenerated hex mesh

Addressing the Challenges of the Design of Hypersonic Vehicles with Simulations
The recent surge in the interest in hypersonic technology has highlighted the need to accurately and efficiently simulate these complex flowfields using CFD tools. Computer simulations for the design and analysis of hypersonic vehicles is critical since it is often impossible to reproduce the high-Mach number, high-enthalpy conditions in a wind tunnel.
Simulating the hypersonic flow regime with CFD tools presents several challenges, ranging from the accurate modeling of the complex physical phenomena, such as compressibility effects, shock-boundary layer interaction, high temperatures, dissociation and ionization of air, ablation of solid surfaces and, ultimately, magnetohydrodynamics effects, to the stabilization of the numerical algorithms used to solve the governing equations.
In this seminar we will show how ANSYS CFD tools are used to simulate high speed flows and to design hypersonic vehicles, by touching on the capabilities of the CFD tools and describing case studies.

Multiphysics Simulation For The Aerospace Industry
Modern trends in the development of aircraft and defense vehicles, such as increased power density, miniaturization, lightweighting, advanced materials and environmental sustainability are driving the need for Pervasive Engineering Simulation. Upfront digital exploration and building of digital twins require a comprehensive simulation platform that enables the modeling of complex physical and physics-based interaction of systems. Robust, fast, scalable and versatile workflows for multiphysics simulations offer tremendous value to companies in their product development and operation cycles.
This webinar presents the ANSYS multiphysics solution specifically for the A&D engineer. We will highlight how the ANSYS solution works and showcase fluid-structure interaction (FSI) case studies and examples from the A&D industry.

Addressing Challenges of High-Speed Vehicle Design Using Physics-Based Simulation Technology
In this webinar, we focus on the numerical study of the external aerodynamics of two cruise missile geometries. The first is a generic high-supersonic/low-hypersonic geometry. The study analyzes the main flow features to better understand the physical phenomena that govern the behavior of canard geometries at different angles of attack.
The second geometry is an aerospike. It uses an aerodynamic spike on the nose of the missile to offset the shockwave in front of the main body and effectively reduce pressure and temperature loads on the radome. The study explores the complex flow field around the missile and includes a sensitivity analysis.

Designing Safer Ships Using Simulation: Ship-Hull Stability Prediction by ANSYS CFD
As part of the certification process, marine surface vessels and industrial floating structures undergo rigorous stability tests to insure the maximum safety and operability under extreme weather conditions.
In this webinar, we will demonstrate how CFD analysis can be used to gain insight into the stability performance of a representative Navy vessel using ANSYS Fluent. The free surface effects on the vessel were simulated using the Volume of Fluid Method, while the vessel motion was resolved using the 6-DOF solver.

Improving the Design of Fuel Cells for the Aerospace and Defense Industry
Fuel cells can produce electricity from an external source of fuel and oxidizer. They are clean, quiet and highly efficient. Polymer electrolyte membrane (PEM) fuel cells (FCs) operate at lower temperatures than other types of fuel cells and are frequently employed in vehicles and personal mobility applications in the aerospace and defense industry. This webinar will focus on the application of the PEMFC module in ANSYS Fluent to both simple and complex fuel cell geometries to help understand the effects of geometric and operating parameters on device performance and thermal management.
