Description
Summary:In order to analyze the thermal behavior of the stratospheric airship more accurately, a thermal model, which takes account the effect of the diaphragm on the thermal behavior of the double-gasbag stratospheric airship is investigated. The calculation method of the internal radiative heat flux of the double-gasbag stratospheric airship is proposed based on the net heat method. And the thermal model of the double-gasbag stratospheric airship is studied. A numerical simulation for the double-gasbag stratospheric airship at high-altitude station-keeping condition is conducted. The results show that the diaphragm has a great influence on the thermal behavior of the stratospheric airship, which lays the foundation for further research on the thermal model of the stratospheric airship in multi-gasbag case.
