The invention provides a continuous rotation detonation ramjet engine capable of supplying oil and gas in the radial direction, and belongs to the technical field of aero-engines, the continuous rotation detonation ramjet engine comprises an oxidant injection mandrel used for oxidant inflow, a fuel pressure stabilization cavity used for fuel pressure stabilization and a combustion chamber, and a pressure stabilization space is formed in the oxidant injection mandrel; a plurality of first gaps are evenly distributed in the oxidizing agent injection mandrel, oxidizing agents enter the combustion chamber through the first gaps, and a plurality of second gaps used for introducing fuel into the combustion chamber are evenly distributed in the radial direction of the fuel pressure stabilizing cavity. According to the ramjet engine, the feeding direction of fuel is changed into the radial direction, so that the fuel and an oxidizing agent are subjected to radial hedging in the combustion chamber, and good mixing is
