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 ANU Rocketry: Democratisation of Space starts with university student teams

      Founded in 2018 to participate in the Australian Universities Rocket Competition (AURC), students from the Australian National University’s (ANU) Rocketry team are striving to develop a rocket capable of passing the boundary of outer space and being safely recovered by parachute upon re-entry. This lofty goal has led the team to move away from commercially available solid-fuel propelled rockets to develop their own in-house designed bipropellant liquid-fuel engine, with the help of Ansys aerothermal analysis to predict the heat flux at the space rocket’s leading edges during its hypersonic ascent phase.

          Ansys 2022 R1 is now available – watch our recent update session with Prof. David Fletcher who discussed the new features of greatest interest to our customer base, including improvements in performance, usability, speed and model physics.

          How to Benefit from Decades of Experience in Turbulence Modelling

          David Fletcher from LEAP discusses the importance of the 3rd Turbulence Best Practices guide recently released by Florian Menter and his team at Ansys.
          This latest BPG documents the key best practices in RANS turbulence modelling, with comprehensive coverage of all widely-used 1-equation, 2-equation and Reynolds stress models.

          Guest Blog by ECU-R: Analysing F-SAE Aerodynamic Flow Fields Using CFD

            Guest blog by ECU-Racing on how the team uses CFD simulation to drive aerodynamic design improvements, explaining how CFD simulation results provide help identify problematic aspects such as flow separation, undesirable flow structures, and poor use of flow energy which can then lead to new ideas which can be tested in CFD to improve the overall flow around the car.

            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.
