Micro aero-engine fuel manifold nozzle and oil mixing test method thereof

The invention discloses a micro aero-engine fuel manifold nozzle. The micro aero-engine fuel manifold nozzle comprises a nozzle base, a rotational flow core, an auxiliary nozzle and a main nozzle. The auxiliary nozzle is arranged in the main nozzle; after the main nozzle is installed on the nozzle base, the left end face of the auxiliary nozzle is pushed to be tightly pressed on the right end face of the nozzle base. The left end of the rotational flow core is arranged in the nozzle base, and the right end of the rotational flow core is arranged in the auxiliary nozzle. A base auxiliary oil duct and a base main oil duct are arranged on the nozzle base; a blind hole with an open left end is formed in the rotational flow core, and a radial hole communicated with the blind hole is formed in the right end of the rotational flow core; the base auxiliary oil duct, the blind hole, the radial hole and the inner molded surface of the auxiliary nozzle jointly form an auxiliary oil way; the base main oil duct, the outer
