A New Manner for Energy Reintroduction in AJAX

Much attention has been focused on a revolutionary hypersonic propulsion system named AJAX, and the poor performance of MHD accelerator has been demonstrated by computational and experimental efforts, which is the key component for energy reintroduction in AJAX. The reason for the poor performance of MHD accelerator is investigated in this paper, and the explorative work about a new manner for energy reintroduction is carried out, in which arc technology is supposed to displace MHD accelerator. Some discussions for the above two cases are investigated qualitatively and quantitatively based on thermodynamic principal, and the comparative analysis results show that the engine specific thrust for the case of arc technology is equivalent to that for the case of MHD accelerator under ideal and undeal computational condition respectively
