Description
技术领域Technical Field
本发明涉及防雹火箭相关技术领域，具体为一种防雹火箭用焰剂炉。The invention relates to the technical field related to hail-proof rockets, and in particular to a flame furnace for hail-proof rockets.
背景技术Background technique
防雹火箭是一种人工影响天气、预防冰雹形成以减少其危害的高空作业工具，火箭从地面点火发射，由固体燃料发动机提供推力，将火箭送达到云中预定的高度，点燃催化剂焰剂，随着火箭的飞行，沿途播撒催化剂，改变云层的微物理结构，从而达到减弱和消除冰雹的目的。增雨防雹火箭上焰剂炉是防雹火箭的关键部件，它是防雹火箭有效载荷，为防雹火箭提供催化剂焰剂燃烧室并喷出含气溶胶烟雾，实现播云作业，其性能的优劣关系到防雹火箭作业效率、催化剂有效撒播效率等问题。The hail-prevention rocket is a high-altitude tool for artificially influencing the weather and preventing hail from forming to reduce its harm. The rocket is ignited and launched from the ground. The solid fuel engine provides thrust to send the rocket to a predetermined height in the cloud and ignite the catalyst flame. As the rocket flies, the catalyst is spread along the way to change the microphysical structure of the cloud layer, thereby achieving the purpose of weakening and eliminating hail. The flame furnace of the rain-enhancing and hail-prevention rocket is a key component of the hail-prevention rocket. It is the payload of the hail-prevention rocket. It provides the hail-prevention rocket with a catalyst flame combustion chamber and sprays aerosol-containing smoke to achieve cloud seeding operations. The quality of its performance is related to the operating efficiency of the hail-prevention rocket and the effective spreading efficiency of the catalyst.
现有的焰剂炉存在以下不足：The existing flame furnace has the following shortcomings:
1.焰剂药柱端面或内孔圆柱表面燃烧方式，药柱内孔直径小，药量较小，燃烧面积小，催化剂燃烧烟雾量有限，影响催化剂播撒效率；1. The flame charge column end face or inner cylindrical surface combustion mode, the inner hole diameter of the charge column is small, the charge amount is small, the combustion area is small, the catalyst combustion smoke volume is limited, which affects the catalyst spreading efficiency;
2.焰剂炉外壳体多采用酚醛树脂布棒材料，为保证飞行中其壳体强度及刚度，壳体壁厚很厚，减少了催化剂药柱直径，即减少了催化剂药量，从而降低来火箭作业播撒效率，提高作业成本。2. The outer shell of the flame furnace is mostly made of phenolic resin cloth rod material. In order to ensure the strength and rigidity of the shell during flight, the shell wall thickness is very thick, which reduces the diameter of the catalyst column, that is, reduces the amount of catalyst, thereby reducing the rocket operation spreading efficiency and increasing the operation cost.
