The invention discloses an icing wind tunnel nozzle based on feedback adjustment of different distribution forms, and belongs to the technical field of nozzle structure design, the icing wind tunnel nozzle comprises an inner nozzle body and an outer nozzle body sleeving the outer side of the inner nozzle body, the outer nozzle body and the inner nozzle body are separated to form a conical air guide cavity, a spraying hole is formed in the center of the outer nozzle body, and a nozzle opening is formed in the outer nozzle body. The spraying hole is located in the tail end of the air guide cavity, a liquid inlet channel corresponding to the spraying hole is formed in the center of the inner nozzle body, and a liquid spraying opening with the small diameter is formed in the side, facing the spraying hole, of the liquid inlet channel. A plurality of first air inlet channels are annularly and evenly distributed on the outer side of the liquid inlet channel, a spray pipe is hinged to the interior of the baffle in a
