During enforcement, meet with hail weather swallow hail for simulating aero-engine, hail physical attribute requires respectively as follows: proportion is 0.8 to 0.9,1 diameter be 51mm and 2 diameter is the hail of 25.4mm, and the temperature of hail is between-2.2 DEG C ~ 0 DEG C.For making the hail and the borneol that meet above-mentioned requirements, the present invention mainly comprises the preservation of ice making Mold Making, ice making method, ice.
Hail ice making mould
Ice making mould comprises ice mould 1 and lower ice mould 2, and upper ice mould 1 spherical tips (episphere mould 3) is provided with water filling spout hole 5, can inject ice making water by water filling spout hole 5 to mould inside.Meanwhile, due to water volumetric expansion in the process of build-uping ice, water filling spout hole 5 also can ensure that unnecessary water is flowed out by water filling overfall in guarantee ice type condensation process, thus ensure that ice type shape and size.As shown in Figure 2, large ice pellet structural dimensions is in table 1 for ice making mould structural dimensions.
In order to ensure the integrality of ice hockey, preventing upper/lower die junction from seeping water causes ice type to lack, upper ice mould 1 mould height and lower ice mould 2 mould high size, slightly larger than radius of ice sphere (episphere mould 3 inwall radius size or lower semisphere mould 4 inwall radius size), ensure that ice hockey inside liquid level is in expanded state all the time.
After ensureing that ice making completes, facilitate ice to take out, upper and lower ice mould all adopts silica gel material, utilizes 3D printing technique shaping.Because silica gel is soft, and good springiness, model needs shape can be ensured, facilitate shaping ice hockey to take out simultaneously.
Table 1 hail mould structural dimensions
Hail preparation method: first lower ice mould 2 is placed in horizontal level, respectively to water filling in two ice hockeys in lower ice hockey (lower semisphere mould 4), until be full of water in hemisphere.Buckle ice mould 1, ensure that upper and lower ice mould faying face is adjacent to, utilize syringe to inject ice making water afterwards in water filling spout hole, till water overflows in spout hole, in refrigerator inside mould being placed in-2 DEG C ~-1 DEG C or freezer, take out after 24 hours, pull down ice making mould.
The preservation of ice
The borneol of taking-up or ice hockey are placed in refrigerator-freezer or the freezer of-2 DEG C ~-1 DEG C, take out before treating to carry out gulping down ice test.
The invention provides and can be used for the concrete grammar that aero-engine complete machine gulps down ice test ice, the making gulping down ice test ice of great convenience.The present invention Successful utilization gulps down the making of ice test ice in certain turboshaft engine complete machine, result proves that the method is feasible.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
