VKI Travel to AvMC and Materials conference
Abstract
The von Karman Institute (VKI) plans to send two researchers to the DEVCOM Aviation & Missile Center as part of the currently ongoing collaboration between the US Army and VKI on high-temperature material research in plasma facilities. Several related research topics have been identified as of interested to both partners, they are (but not restricted to): 1) Ongoing research on passive/active oxidation of ceramic materials: The research project between VKI and the US Army includes a limited number of test samples and experimental runs that may serve to pave the way towards a larger, more comprehensive follow-up investigation. In this research approach we will revise the available experimental and numerical tools at VKI for CMC material characterization, investigate new flow regimes, and possibly extend to new materials (pending material procurement, for example, oxide ceramics). We plan to discuss the following specific research objectives: ¥ Presentation of the plasma wind-tunnel capabilities and the testing strategy ¥ Definition and conduction of experiments in passive and active oxidation regimes ¥ Extension of experiments to supersonic operation regime ¥ Post-test analysis, numerical rebuilding (of the applicable cases), and interpretation of test results including a preview on possible uncertainty quantification (UQ) techniques 2) Morphing structures and surfaces (high interest at VKI and also ARL) Main interest by ARL about any VKI activities related to actuators and controls for adaptive systems, flexible TPS, and discuss possible ablation testing for validation of their CFD models. 3) Supersonic plasma testing and nozzles (more of interest to ARL than to AvMC), another possible visit is foreseen at ARL in January 2022 in parallel to the AIAA SciTech conference. Discussions on conversion of ARLÕs jet burner rig facility and the possibility of establishing a CRADA framework to enable further collaboration. 4) US3D discussion with our numerical specialist Alessandro Turchi and AvMC scientists James Lusk, and Peter Cross 5) Visit and discussion at the 12th ablation workshop in Kentucky Lexington: ¥ foster improved communication across national boundaries; ¥ expose the aerothermodynamic ablation modeling community to new ideas and techniques from adjacent disciplines; ¥ bring new experimental techniques to bear on the problem; ¥ discuss challenges faced in adapting existing techniques to address new applications.
