Problems solved by technology

However, since this type of balloon itself has good stretching performance, a slight pressure difference between the inside and outside of the ball can make the balloon skin stretch outward (ie expand), so it is difficult to achieve flat drift at a certain height.

Embodiment 1

[0035] This embodiment provides a method for launching latex sounding balloons at night by Linhe Meteorological Bureau in Inner Mongolia, specifically:

[0036] (1) Determine the mass m of the latex sounding balloon itself 球 0.78kg, load mass m 载 It is 0.65kg; determine that the target level drift height h of the latex sounding balloon is 25km, and inquire about the temperature T of the atmosphere at a height of 25km h About 224.5K, pressure P h About 27.2hPa, density ρ hAbout 0.0421kg / m 3 ; At the same time, query the temperature T of the ground atmosphere in the release area 地 About 293K, pressure P 地 About 1000hPa and atmospheric density ρ 地 About 1.293kg / m 3 ;

[0037] (2) Calculate the ground net lifting force F when the latex sounding balloon is released according to the following formula 举 :

[0038]

[0039] Where: when the balloon is on the ground, the gas pressure inside the ball is P' 地 Equal to the surface atmospheric pressure P 地 , which is 1000hPa,...

Embodiment 2

[0047] This embodiment provides a method for launching latex sounding balloons by Linhe Meteorological Bureau of Inner Mongolia during the day.

[0048] On the basis of Example 1, consider the temperature change inside the ball caused by solar radiation, and add solar radiation correction; according to the correction, the temperature inside the ball is about 28°C higher than the atmospheric temperature, and the net lifting force F on the ground during the day is calculated. 举 It is -0.12kg*g, that is, 1.2N; fill hydrogen into the latex sounding balloon, stop inflating when the net lifting force on the ground of the balloon reaches 1.2N, and release the balloon.

[0049] After the actual release operation, the latex sounding balloon released according to the above scheme can float at a height of 25km for 5 hours.

Abstract

The invention provides a releasing method for an expanded type horizontal floating sounding balloon. According to the method, parameters such as preset horizontal floating height atmosphere pressure,temperatures and densities are checked, assisted by balloon skin pressure differences and temperature radiation modification, a net ground lifting force of a released expanded balloon is calculated, the balloon is released when meeting a specific net ground lifting force, and a function of fixed-height horizontal floating of the expanded balloon can be achieved. Aiming at an expanded balloon whichis small in manufacturing technique difficulty, high in cost performance ratio and very convenient and rapid to release, the invention provides a method for releasing the balloon by confirming the net ground lifting force, the result that balloon skin is expanded outwards because of pressure differences inside and outside the balloon can be avoided, and thus long-term horizontal floating of the expanded type horizontal floating sounding balloon at a certain height can be achieved.

Description

technical field [0001] The invention relates to the field of high-altitude meteorological detection, in particular to a launching method of an inflatable flat-drift sounding balloon. Background technique [0002] The sounding balloon is made of rubber or polyester film material, filled with hydrogen or helium, which is less dense than air, and carries the sounding instrument into the sky. Density, wind direction, wind speed, temperature, humidity, electric field strength, electron density, ion density, etc.) for in-situ detection. According to the different materials of the balloon skin, it is mainly divided into two categories: inflatable and non-expandable. The inflatable type mainly refers to the use of natural rubber latex as the main material to make the ball skin, and the buoyancy generated by the gas whose inner filling density is lower than that of air is used as the lift-off power. Stretchability The continuous expansion provides more and more volume to maintain t...
