Abstract
The atmospheric flights of the supersonic combustion (scramjet) demonstrators carried out by Russia (Hypersonic Flying Laboratory, HFL scramjet, 1993, 1994 and 1998), by Australia (HyShot, 2002), by USA (X-43 2002, and X-51, from 2010 to 2014), gave a new revival for a new design of the advanced aerospace vehicles using airbreathing propulsion systems. Currently, one of the most important issues to be dealt with is how to improve the fuel (hydrogen) injection and hydrogen-air mixing and burning efficiency and make the flame stable in supersonic flows, and, evidently to generate thrust for the scramjet vehicle. The ongoing research efforts on fuel injection techniques in the scramjet combustion chamber have been reviewed. Single and double cavity-based supersonic combustors, the oblique shock-induced combustion, the combination of oblique shock-induced combustion and a single cavity-based supersonic combustor, the backward-facing step, the strut injection will be discussed. The flow field characteristics and research efforts related to these fuel injection techniques are summarized and compared. Finally, a promising fuel injection technique will be discussed.
