This utility model discloses a rapid curing gas circulation drying chamber for aircraft coatings, including a drying chamber. A circulating air drying mechanism is installed at the upper end of the drying chamber. The drying mechanism includes a slide rod, a screw, a fixed frame, a mounting frame, an axial impeller, a first motor, an air outlet, and a heating pipe. The slide rod is fixedly installed at the upper end of the drying chamber. A screw is movably installed between the slide rods inside the drying chamber via bearings. The fixed frame is movably fitted onto the surface of the slide rod, and the inner center of the fixed frame is threaded onto the outer surface of the screw. This utility model can perform reciprocating hot air drying and curing, ensuring a consistent drying temperature throughout the entire space of the drying chamber. Simultaneously, the continuously moving airflow effectively prevents direct airflow onto a fixed location on the aircraft parts, effectively preventing blistering of the coating due to high temperatures, thereby improving the drying and curing effect of the device.
