The Impact of Fluid-Thermal-Structural Interactions on Hypersonic Vehicle Performance.

Aerothermodynamic heating is an unavoidable consequence of high-speed flight. This presents design challenges for hypersonic vehicles that must be understood and addressed. Even at moderate hypersonic Mach numbers, elevated structural temperatures can distort the airframe of a vehicle, its control surfaces, and propulsion flow paths, degrading performance and reducing life. Multifidelity simulation approaches must be optimized for an appropriate balance between efficiency and accuracy, depending upon their application in the design cycle. Detailed validation cases are required to build confidence in these approaches but these data sets, whether from ground-based or flight experiments continue to be limited. This webinar will explore these challenges and discuss recent experimental approaches developed at UNSW Canberra to build confidence in numerical design tools.

Challenges and of Hypersonic Flight Experiments using Sounding Rockets

In this webinar Ali Gülhan, German Aerospace Center (DLR), will discuss how high-quality validation data that is representative of the real flight environment is necessary for the simulation-based design of flight hardware. Since ground testing facilities have limitations to duplicate the flight environment and numerical tools still have shortcomings in modelling high temperature gas phenomena and gas-surface interaction in such environments, availability of flight data is essential. A complementary validation approach using ground and flight testing for gathering reliable data and validation of numerical tools also is required. Gülhan will explain how simulation of the hot hypersonic flight environment in ground facilities is limited and requires data from further flight experiments. Hypersonic flight experiments by means of multistage sounding rocket configurations are seen as the most cost-efficient options to gather valuable flight data.
