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.

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.

Addressing Challenges of High-Speed Vehicle Design Using Physics-Based Simulation Technology

In this on-demand 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.

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.

View this on-demand 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 interest in hypersonic technology has highlighted the need to accurately and efficiently simulate these complex flow-fields using simulation tools. Computer simulations for the design and analysis of hypersonic vehicles are critical as it is often impossible to reproduce the high-Mach number, high-enthalpy conditions experienced at the high speeds of these vehicles in a wind tunnel.

Simulating the hypersonic flow regime with CFD tools presents several challenges, ranging from the accurate modeling of 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 on-demand webinar we will show how ANSYS tools are used to simulate high speed flows and to design hypersonic vehicles, by highlighting the capabilities of the CFD and multiphysics tools and by showing select case studies.
