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.

Prediction and Remediation to Aircraft Icing via Simulations

November 20, 2019
11 AM EDT / 3 PM GMT

Icing on aircraft surfaces, appendages, sensors and engines are safety-critical aspects of aircraft design that impact the whole supply chain. Achieving regulatory certification is a complex and time-consuming process involving simulation models, icing tunnels and flight testing. Recent regulatory changes and industry focus around high-altitude ice crystals and supercooled large droplets (SLD) have further challenged the design process and the time to market for new aircraft and technology.

ANSYS provides a unique combination of advanced computational fluid dynamics and icing simulation expertise in a common working environment. The solution captures real-world behavior in 3D, using the most efficient simulation workflow available and an extensive database of industry validation. In addition, the simulation outputs are designed to comply with the FAA’s Appendices C, D and O.

ANSYS icing simulation enables companies and engineers to develop products faster, test designs earlier in the development cycle, reduce the number of physical prototypes and produce a better solution than would be possible using traditional design methods.

Please join us for this webinar to learn about the capabilities and applications of ANSYS software for in-flight icing.

Aircraft Engine Icing

Recent events of high-altitude turbofan engine malfunctions characterized by sudden power loss and flameouts have been attributed to ice crystal formation in the compressor core. The understanding of ice accretion on rotor/stator blades is paramount and needs to be accounted for and integrated into the gas turbine design process.

Designing optimal anti/de-icing systems requires detailed understanding of complex icing phenomena and their interaction with air flow and ingested particles. Regulatory certification processes are often underpinned with expensive ice tunnel and flight tests with limited data points. High-fidelity CFD/icing models can help engineers develop a better understanding of complex icing processes and design better systems at a fractional cost.

ANSYS icing solutions empower engineers with high fidelity CFD/icing models to account for ice accretion and flow interactions early in the design phase in a seamless manner while harnessing the power of high-performance computing. Attend this webinar to get an overview of ANSYS icing solutions with a focus on ice crystal formation in turbomachinery compressors.

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.

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.

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.

Accurate Prediction of Panel Flutter Applicable to Supersonic or High Lift Flight: Results and Comparison to NASA Wind Tunnel Data

Avoiding flutter of an aircraft's skin is important for safe and robust operation. Traditional panel flutter prediction tools fall short for conditions where the boundary layer thickness varies. ANSYS’ fluid–structure interaction (FSI) capability accurately predicts panel flutter under the most challenging conditions. ANSYS simulation results will be compared to NASA supersonic wind tunnel data. The simple simulation process and surprisingly small computational requirements for accurate results will also be summarized. Prime applications for the ANSYS FSI capability include next generation supersonic transports heralded by NASA's (X-59) low boom demonstrator or high lift flight conditions of subsonic aircraft.

Reduced Order Modeling (ROMs) for Aerospace Industry

Assessing the performance of aircraft components with systems-level models has always been a part of the aircraft design process. A systems simulation is a collection of models, simulations and algorithms that predict how all the parts in a system will work together. The fidelity of the model improves if the detailed physics governing the performance of the components can be closely represented in the system model. However, the very nature of 3D modeling is time-intensive and not practical to incorporate in a full systems-level model you need to simulate a system in real time.

Reduced Order Models (ROMs) are mathematical simplifications of 3D models that preserve the essential information needed for system simulations. Solving a ROM for a given input can be orders of magnitude faster than solving a 3D model. This makes ROMs ideal for many applications, like design of experiments (DOE), systems simulations, digital twins and runtime generations of real-time applications..

This webinar will present an overview of ROM technology available with the ANSYS platform, along with some examples and a demo of the ROM workflow for CFD..
