Simulating Aerothermal Shape Distortion of Hypersonic Vehicles

How can designers of hypersonic aircraft overcome the ‘heat barrier’ using simulation to better understand aerothermal shape distortion (aka aerothermoelasticity, or fluid-structural-thermal interaction - FTSI)? This guest blog by ADFA explains how multiphysics simulation helps designers of hypersonic vehicles account for aerothermal shape distortion (which can compromise a hypersonic vehicle’s aerodynamic performance) through to the risk of catastrophic material failures, using tools that can simulate both the aerodynamics as well as the thermal and structural response.

Guest Blog by Prof. David Fletcher: Importance of following Best Practices for Scale Resolving Turbulence Modelling

Guest Blog explaining the significance of the new Stress-Blended Eddy Simulation (SBES) turbulence approach which makes use of the best available models for both near-wall and far field accuracy, within one single scale-resolving CFD simulation, including a recording of highlights from our recent webinar.

Helping EO/IR Sensors to accurately detect & track hypersonic vehicles

Learn how recent developments in Ansys provide a new “optical CFD” workflow to help more accurately simulate the complex interactions between the flowfield and electromagnetic fields in the Electro-Optics / Infra-Red (EO/IR) range. This helps engineers to improve their simulations of flow field phenomena around fast-moving vehicles and improve the performance of EOIR sensor signals for tracking hypersonic vehicles.

Guest Blog by USYD Rocketry Team (URT) who use simulation in their development of high-power sounding rockets to compete in the Australian Universities Rocketry Competition (AURC) and Spaceport America Cup. URT was the first Australian team to compete and took first place in the 10,000 ft COTS category with their Silvereye rocket.

Join LEAP at the 2013 Australian International Airshow

We know that many of our CFD customers are also very passionate about aerodynamics and aircraft design, so it stands to reason that the 2013 Australian International Airshow will be a magnet for both aircraft enthusiasts and CFD practitioners alike.  The Australian International Airshow starts today (Feb 26th 2013) and LEAP Australia staff will be attending as...
