Weather balloon and preparing method thereof

Abstract

The invention provides a weather balloon which comprises a sounding balloon body. The sounding balloon body comprises a balloon base body and a water-based waterproof coating which coats the surface of the balloon base body. The water-based waterproof coating is a macromolecular polyurethane coating. The invention further provides a preparing method of the weather balloon. The weather balloon can be used in the severe weather. The elongation at break, the tensile strength and the stress at definite elongation are good, the difference of the elongation at break and the tensile strength before and after ageing is not huge, and the swelling phenomenon is avoided. According to the launching experiments carried out on the condition of the severe weather, the average lift-off height is more than 29000 meters, the effective rate of the lift-off height of 26000 meters is more than 81.8%, and the requirement for the weather balloon at present is met.

Description

technical field [0001] The invention belongs to the field of meteorological detection, in particular to a weather balloon and a preparation method thereof. Background technique [0002] Meteorological balloons are important and indispensable vehicles for studying the atmosphere, developing meteorology, aviation, space flight technology and conducting space science research. [0003] At present, in order to learn more about the interaction between the upper and lower atmospheres and the disturbance transmission process under severe weather such as rain, snow, freezing, and strong winds, it is beneficial to observe the processes of transmission, absorption, and photochemical reactions of solar ultraviolet radiation in the stratosphere and middle atmosphere. The study of the overall physical process of the atmosphere is beneficial to changes in stratospheric circulation, further improves the detection height and detection level, provides accurate and timely services for meteoro...

AI Technical Summary

Problems solved by technology

[0004] And although the weather balloon in the prior art can reach the altitude of about 30,000 meters under normal weather conditions, under severe weather conditions such as rain, snow, freezing, strong wind, the lift-off height of the balloon is greatly reduced, and unstable, for example The average detection height of a 750-gram balloon is about 18,000 meters, and the minimum detection height is about 12,000 meters. Even if the mass of the balloon is increased, it is difficult to effectively solve the problem of lift-off height, which is far from the detection height of 26,000 meters required by the detection specification. The effective rate of the meter height is less than 50%, resulting in the lack of high-altitude data of the station, affecting the accuracy of weather forecast and meteorological scientific research

Although the weather balloon can solve the problem of the lift-off height of the balloon in bad weather, there are many inconveniences in its use. The biggest disadvantage is that it is inconvenient to store. After a long time, the performance of the balloon will easily decrease, and it will also cause additional troubles to the caster, such as causing greasy pollution to the venue, etc.
