Abstract: In order to regulate the thrust of solid fuel ramjet,a new inner bypass structure was presented,and the flow field characteristic of the structure was numerically studied.It was concluded that the thrust can be regulated with regulated bypass air mass flow rate.A symmetrical vortex was found in the head of afterburning chamber which could enhance the combustion.The inner bypass structure is attractive because it does not require the aft bypass supersonic inlet and the mass and drag of the missile can be reduced.
