The initiation of oblique detonation waves (ODWs) is a key component the successful application wave engines (ODWEs). This paper numerically investigates ODWs under active control transverse jet by solving two-dimensional multi-species Euler equations, focusing on morphology flow fields as well relationship between structures and propulsive performance using concept thrust potential. Active significantly shortens length ODW. results reveal that jet-induced field shows four typical patterns depending momentum flux ratio wedge angle: shock-induced combustion, type I pattern, II I-II pattern. For ODW field, declines increases when angle certain. larger angle, greater magnitude decline. consists two main components: generated mixture passes first through shock then wave, directly front. Since upstream front has loss higher potential lower. work could guide at low losses.
