Abstract

The invention is applicable to the field of aerospace technology, and provides an airflow pulse shear type single droplet generating device, including a water supply system, an air supply system, a synchronizer, and a water droplet generator; one end of the water supply system and the air supply system are connected In the droplet generator, the other end of the water supply system and the air supply system are connected to the synchronizer; the water supply system provides water to the droplet generator, and the water supply speed can be adjusted; the air supply system provides pulsed airflow to the droplet generator, and the pulsed airflow generates The frequency is adjustable. Further, the water supply system includes a displacement controller, a linear displacement meter, and a microinjector connected in sequence, wherein the displacement controller is connected to the synchronizer, and the microinjector is connected to the droplet generator. The airflow pulse shear type single droplet generating device of the present invention can realize the adjustment of the diameter of the water droplet and the adjustment of the spacing of the water droplet.

Description

Technical field [0001] The invention belongs to the field of aerospace technology, and in particular relates to an air pulse shear type single droplet generator. Background technique [0002] Since the US ATR-72 air crash in 1994, Supercooled Large Droplet (SLD) has become a hot spot in aircraft icing research. Compared with the conventional water droplets specified in Appendix C of FAR 25 (the average effective diameter of the water droplets is less than 50μm), SLD is characterized by a large water droplet diameter (usually greater than 100μm, or even more than 3mm), and significant power will occur during movement and impact. For example, deformation and breakage may occur under the action of strong aerodynamic force, spreading, shrinking and splashing may occur when hitting a solid wall or liquid film; at the same time, SLD usually does not freeze immediately after hitting a solid wall. Most The situation will form a liquid water film and gradually freeze during the process o...
