Setting a transverse hydrogen jet in the induction zone is an effective active control scheme to implement the controllable and fast initiation of an oblique detonation wave （ODW） under high altitude flight conditions.In this paper，the flow characteristics of the ODW induced by a transverse hydrogen jet and the effects of the jet dynamic pressure ratio and jet angle are studied by solving the two-dimensional reaction Euler equations.The results show that the accelerated initiation of an ODW can be implemented by setting a transverse hydrogen jet in the induction zone.The jet-induced ODW has two initiation patterns，i.e.，strong coupling and weak coupling.In addition，the height of the ODW at the exit of the combustor is proportional to the jet dynamic pressure ratio and jet angle，and the active control of the ODW can be implemented by changing the jet dynamic pressure ratio and jet angle.Therefore，with proper jet dynamic pressure ratio and jet angle，the stable operation of ODW engine can be achieved.
