The present invention provides a mixer structure for an air-turbine rocket engine, which includes a jet annulus, a swirl vane, and a center cone. Along the gas flow direction, the front end of the center cone is a hemisphere, which serves to reduce the total pressure loss. The rear part of the center cone is a circumferential groove, and the circumferential groove is covered by an annular partition to form an internal flow passage. The annular partition smoothly transitions with the outer wall surface of the center cone, and the overall shape is a frustum of a cone. A jet annulus is formed between the annular partition and the outer wall surface of the center cone, and the jet annulus connects the internal flow passage with the external flow passage outside the annular partition and the center cone. The internal flow passage is a gas flow passage, and the external flow passage is an air flow passage. The gas in the internal flow passage can enter the air flow passage from the jet annulus and mix with the air. The present invention is a passive mixing structure. Compared with the active mixing structure, this type of structure is simple, reliable, and has a good mixing effect. In addition, compared with other passive mixing structures, this structure can achieve full fuel mixing within a shorter distance while ensuring a lower total pressure loss.

Blades are installed on the shaft. The tank inlet is an inlet nozzle located in the cover, and the outlet is an outlet nozzle located in the conical bottom. Mixing device is made in the form of a vertical shaft with horizontally installed blades with an angle of attack of 0°, at the ends of which conical impellers are installed. Radial part of the blades can be made in the form of a rod. The execution of horizontally installed blades with an angle of attack of 0° prevents active mixing and foaming around them.EFFECT: invention can be used both in the production of new tanks and in the reconstruction of those in operation at oil and gas industry enterprises in installations for introducing drag-reducing additives into an oil pipeline.2 cl, 3 dwg
