| Abstract: | The prediction of the thermal behavior of stratospheric balloons under varying environmental conditions is one of the key issues in the design and flight test of balloons. In this paper, a three-dimensional transient thermal model is developed to predict the thermal behavior of spherical stratospheric balloons. The diurnal variations of the skin and lifting gas temperatures at float conditions are discussed in detail. The further studies on the thermal behavior of stratospheric balloons are presented also. |
