Flow disturbing device for solid rocket fuel gas supersonic combustion ramjet engine

The invention discloses a flow disturbing device for a solid rocket fuel gas supersonic combustion ramjet engine. The flow disturbing device comprises a flow disturbing device body used for being placed in an isolating section of the solid rocket fuel gas supersonic combustion ramjet engine and dividing the interior of the gas inlet channel isolating section into two gas flow channels on the leftside and the right side of the flow disturbing device. The flow disturbing device body comprises a wedge section, an equal straight section and a staggered section which are sequentially connected from front to back, and the upper, lower, left and right side faces of the staggered section and the corresponding side faces of the equal straight section are located on the same planes correspondingly.The staggered section is internally provided with one or a plurality of primary fuel gas channels from front to back, and when the multiple primary fuel gas channels are arranged, and the primary fuel gas channels are arrange
