Jet injection into a supersonic cross flow is a basic way of introducing fuel into a supersonic combustor. Engines with supersonic combustors are needed for hypersonic vehicles with airbreathing propulsion. Shown here are some pictures of gaseous injection tests conducted at UCI a few years ago. It is hoped that these experiments will continue with liquid injection into a supersonic cross flow using our special mixing enhancement methods to distribute fuel evenly inside the combustor.
