The stratospheric airship non-forming descent path simulation and analysis

Abstract

In recent years, with the development of aviation technology, the airship has many advantages compared to conventional aircraft by the concern in many countries. United States, Germany, Russia, China and many other countries show great interests in the potential applications of the airship. Because the airships volume is very huge, so the landing process will inevitably cause a threat to the security of airline and ground facilities, especially the use of non-forming recovery method of stratospheric airship, the landing of security control is more important. This paper analyzes the forces on airship, modeling the airship non-forming decline model, and establishing a drop in direct sunlight, ground reflection, infrared radiation, convection exchange thermal model. According to the parameters of a test platform, the paper simulates the airship track of non-forming declining. Use the experiment data to analyze the simulation results and verify the validity of the model. © Springer-Verlag Berlin Heidelberg 2013.
