­Abstract

Hypersonic air-breathing propulsion systems, such as supersonic combustion ramjets (scramjets), are a key technology for the future of high-speed civil transportation, low-cost access to space and national defense. However, the development of these engines requires a better understanding of the combustion process in supersonic/hypersonic regime. Due to the high costs of real-flight testing at the relevant speed (Mach > 5) and altitude (> 50,000 ft), scramjet development strongly relies on ground-based facilities. ACT-II (Arc-heated Combustion Tunnel II) is a novel pulsed arc-heated hypersonic wind tunnel built at the University of Illinois and aiming to provide a suitable test bench for experimental studies on supersonic and hypersonic turbulent combustion phenomena.

 

This presentation will introduce ACT-II and its capabilities and it will discuss the experimental activities currently in progress, in particular: (1) Turbulent combustion in hypersonic reacting-flows, (2) Flow choking and inlet unstart in a circular model scramjet and (3) Laser breakdown ignition in a supersonic hydrogen/oxygen mixture.

 

About the Speaker

Damiano Baccarella is a PhD candidate in the Department of Mechanical Science and Engineering at the University of Illinois at Urbana-Champaign, working in the group of Prof. Tonghun Lee. His current research is focused on high-speed propulsion systems, supersonic reacting flows and laser diagnostics. Mr. Baccarella graduated with a Master Degree in Aerospace Engineering at the University of Pisa (Italy) in 2006. Later, he spent 7 years as a research engineer at Alta-Space working on experimental aerothermodynamics and electrothermal propulsion. He started his PhD in 2013 at the University of Notre Dame before moving to UIUC in 2015.
