Outdoor crosswind test equipment for aero-engine

The invention provides open-air crosswind test equipment for an aero-engine, and relates to the technical field of crosswind tests.The open-air crosswind test equipment comprises a wind tunnel structure, and the wind tunnel structure comprises an air inlet pipe section, a fan pipe section, a diffusion pipe section, a stabilizing pipe section, a contraction pipe section and a spray pipe section which are sequentially communicated in the airflow direction; fan equipment is arranged in the fan pipe section; the diameter of the diffusion pipe section is gradually increased in the flowing direction of air flow; a plurality of rectification nets are sequentially arranged in the stable pipe section in the flowing direction of air flow; the crosswind test equipment can adapt to an open-air test environment, the on-way resistance loss is reduced through pneumatic and overall layout design, the air outlet flow of the wind tunnel structure is large, the dynamic pressure uniformity is good, and it is guaranteed that the
