The invention belongs to the technical field of aircraft icing testing, and particularly relates to a supercooled water droplet generating device. The supercooled water droplet generating device comprises a water droplet generation module, a water droplet pre-cooling module, a test chamber and a data acquisition module. The water droplet generating module is used for generating water droplets in different diameters and temperatures; the water droplet pre-cooling module is located on the lower side of the water droplet generating module, and the water droplet pre-cooling module is provided with a cooling channel, and used for cooling the water droplets generated by the water droplet generating module to form supercooled water droplets; the test chamber is arranged at the lower end of the water droplet pre-cooling module, and used for providing a solid surface for the supercooled water droplets passing through the cooling channel of the water droplet pre-cooling module to impact for icing; and the data acquisition module is used for acquiring the temperature of the water droplets in the water droplet generating module, the temperature in the cooling channel of the water droplet pre-cooling module and the temperature of the solid surface in the test chamber. According to the supercooled water droplet generating device, the supercooled water droplets in different water droplet diameters, water droplet temperatures, water droplet supercooling degrees and water droplet impact speeds can be generated in the ground normal-temperature environment.
