Embodiment Construction

[0031] The technical solutions of the present invention will be further described below in conjunction with the drawings and specific implementations.

[0032] Such as figure 1 As shown, the method for preparing controllable density hail of the present invention is characterized in that it comprises the following steps:

[0033] S1, ice making;

[0034] S2. Break the ice cubes into crushed ice with an ice crusher;

[0035] S3. Weigh the above-mentioned crushed ice with a mass of M (unit: g) into the squeezing device;

[0036] S4. The crushed ice is squeezed by the squeezing device to compress its volume to L (unit: cm 3 ), where M: L=0.6~0.9 (unit g / cm 3 );

[0037] S5. Take out the crushed ice and spray at least one layer of water mist on the surface;

[0038] S6. Store the crushed ice in a frozen state.

[0039] According to the present invention, crushed ice is extruded to form hail with a density of 0.6-0.9, and the hail produced by this method will not crack or break during high-spee...

Abstract

The invention discloses a density-controllable hail preparation method and an extrusion device for hail manufacturing. The density-controllable hail preparation method comprises the following steps: S1, manufacturing ice; S2, crushing the manufactured ice into crushed ice by using an ice crusher; S3, weighing M (unit: g) of the above crushed ice by mass and putting the crushed ice into the extrusion device; S4, extruding the above crushed ice through the extrusion device till the volume of the crushed ice is compressed to L (unit: cm<3>), wherein the ratio of M to L reaches 0.6-0.9 (unit: g/cm<3>); S5, taking out the above crushed ice and spraying at least one layer of water mist onto the surface of the crushed ice; and S6, storing the above crushed ice in a frozen state. According to themethod, the crushed ice can be extruded to form hail with a set density as required; the hail manufactured through the density-controllable hail preparation method can be prevented from cracking or breaking during the high-speed flight process; the simulation of hail in nature can be effectively achieved; and then the problems encountered in the prior art can be solved.

Description

Technical field [0001] The invention relates to a device and method for making artificial hail with a controllable density, and belongs to the field of air cannons. Background technique [0002] The mechanism of hail formation in nature is complex, and its specific gravity is generally between 0.8-0.9. Aeroengines often encounter hail impacts during operation, causing mechanical damage to components and the entire machine. In order to ensure the engine's anti-hail impact performance, a large number of hail impact tests and analysis work need to be carried out in the design stage. Artificial hail is frozen in a mold by pure water, and its specific gravity is about 1, which cannot meet the density requirements of natural hail. At present, there is no method for preparing artificial hail with controllable density. Summary of the invention [0003] The purpose of the present invention is to provide a device and method for making artificial hail with a controllable density. [0004] To...
