Abstract

The deformation properties of a radiosonde inflatable latex shell (RILS) that provide its necessary performance characteristics are considered. A model of the RILS surface area is proposed and relations between the value of two-dimensional deformation of a thin-walled spherical shell and the deformation properties of a latex sample under uniaxial deformation are obtained. On the example of nine samples of RILS, it is shown that the actual ratio differs from the calculated one due to the influence of external factors. In addition to the geometric coefficient, K₁ ≈ 1,41, which takes into account the transition from one-dimensional to two-dimensional deformations, based on the presented model, it is necessary to introduce an additional coefficient K_m ≈ 1,40, which takes into account the heterogeneity of the material and the difference in test conditions. This allowed us to formulate requirements for the deformation and strength characteristics of the shell material, based on the specified lifting height. The conditions for lifting the RILS to a height of 30 km or more are considered.
