摘要
A thermal characteristics model of the airship was established and the main thermal influence factors were analyzed by taking stratosphere airship as the research object. A complete thermal model of the stratospheric airship was established with the finite split method. The shape was modeled and the surface was discretized in order to make the established thermal model applicable to different types of airships. The distribution parameter method and the lumped parameter method were used to calculate the thermal characteristics of the skin cell and the internal filling gas. The reliability and effectiveness of the established model and its solution method were verified by relevant experimental data. The changes in the surface temperature of the airship and the temperature of the internal filling gas under the influence of 8 different thermal influence factors were calculated, and the qualitative and quantitative effects of each factor were analyzed. The conditions for extreme temperature of the airship skin were summarized. The effects and laws of different heat sources on the thermal characteristics of airships were compared, and a simplified part of the thermal characteristics model of airships was given. © 2020, Zhejiang University Press.
