The invention provides a scramjet engine flow channel structure adopting center combustion and a scramjet engine. The flow channel structure design comprises a support plate injector, a gas inlet flowchannel and a combustion chamber flow channel, wherein the gas inlet flow channel and the combustion chamber flow channel are connected in a smooth transition manner in the flow incoming direction. The support plate ejector is arranged in the combustion chamber flow channel. The axis of the support plate injector coincides with the axis of the combustion chamber flow channel. In the direction ofthe axis of the support plate injector, the cross section of the support plate injector is in an annular shape. By means of the scheme, the technical problem that the low heat protection difficulty and the high air utilization rate cannot be considered at the same time in an existing scramjet engine flow channel scheme can be solved.
