description The invention relates to the technical field of air suction type hypersonic propulsion devices, and provides an ultra-high-speed ramjet engine which is characterized in that an engine body comprises an air inlet channel, a mixing section, a combustion chamber and an exhaust nozzle which are sequentially connected, a first wedge surface unit is arranged on the air inlet channel, and a second wedge surface unit is arranged on the mixing section; the combustion chamber is provided with a combustion chamber wedge surface used for inducing generation of stationary oblique detonation waves, the exhaust nozzle is provided with an exhaust nozzle wedge surface, the second wedge surface unit is provided with a nozzle hole unit used for spraying out propellant mist, and the edge of the air inlet channel and the edge of the mixing section are non-horizontal straight lines. The resistance of the fuel injector is reduced, the mixing and stability of a propellant and air are enhanced, meanwhile, the fuel injection height is
