CONT

La vitesse maximale des statoréacteurs à combustion supersonique (nommés scramjet) reste à déterminer, mais elle semble être supérieure à la vitesse de satellisation (Mach 20 à 25). [...] Dans un véhicule propulsé par un statoréacteur à combustion supersonique, la distinction entre moteur et véhicule est floue : l'air est principalement dévié - et comprimé - par la partie inférieure du véhicule.
