The application discloses a sea-air amphibious fuel injection system and method based on a methanol-activated aluminum-water system fuel, the fuel injection system comprising a needle injection device, the needle injection device having coaxially arranged inner and outer flow channels and a flow regulating unit; the inner wall of the inner flow channel and the inner wall of the outer flow channel have a plurality of inner flow channel bosses and a plurality of outer flow channel bosses arranged alternately along the axial direction, which are used for generating local vortex when the fuel flows; the method comprises: a magnetic stirring device stirring the fuel in a high-concentration Al / MeOH fuel storage tank; a mixing device proportionally mixing the fuel output by the high-concentration Al / MeOH fuel storage tank and a methanol MeOH fuel storage tank; a fuel injection system receiving and injecting the mixed methanol-activated aluminum fuel and introducing seawater or air as an oxidant; the application can enhance mixing through vortex, adapt to seawater / air dual oxidants, adjust the fuel ratio to improve the combustion efficiency, and realize sea-air amphibious high-efficiency power.

This invention discloses a radial flame stabilizer with airflow-assisted jet, comprising an outer wall and an inner wall. Both the outer and inner wall surfaces have V-shaped cross-sections, including a pointed tip and two tail ends. The two corresponding tail ends of the outer and inner wall surfaces are connected by a flow-rectifying wall. An air-guiding groove is provided at the pointed tip of the outer wall, and several injection holes are provided near the tail ends. The air-guiding groove, the interlayer between the outer and inner wall surfaces, and the injection holes form an airflow channel. A fuel injection extension pipe is provided near the tail ends of the inner wall, extending from the inner wall towards the injection holes. The fuel injection extension pipe guides the fuel injection from the injection holes. By introducing a portion of the incoming flow through the air-guiding groove at the stabilizer head, and utilizing the method of coaxial injection of the introduced incoming gas and fuel, the problem of shallow fuel jet depth and difficult evaporation under high-speed, large-flow conditions is improved, resulting in better fuel evaporation and mixing performance compared to conventional radial flame stabilizers.
