Abstract: A fuel - air composite structure taking advantage of a cavity inside supersonic wave flow field prevents the crescent form impulse wave generated in the fuel injection part neighboring. A fuel - air composite structure taking advantage of a cavity inside supersonic wave flow field comprises a fuel injection part(110) which is formed in an intake passage taking in the hypersonic air; and a cavity(120) perpendicularly pitted in the rear side of the fuel injection part from the lower surface of propellant in relation to the intake passage. The cavity includes a parallel section which is parallel formed with the intake passage, and an inclined section which is connected to the rear side of the parallel section and angled with the intake passage.
