The present invention relates to a high-speed propellant provided with a three-dimensional (3D) spray injector, which allows the direction of the propellant to be easily switched according to the direction of the injected air. According to the present invention, a high-speed propellant provided with a 3D spray injector to obtain propulsion by injecting compressed air comprises: an air compression unit connected to an air intake port and a motor to suck and compress the outside air; a spray nozzle for obtaining propulsion by injecting the compressed air generated by the air compression unit; and the 3D spray injector having one end connected to the air compression unit and the other end connected to the spray nozzle to atomize air particles injected by the spray nozzle and change a flow path of the injected air. The 3D spray injector is formed of a plurality of flow path pipes separated from one end and concentrated to the other end, and is configured such that the air particles concentrated through the plurality of flow pipes are atomized by collision.
